Parse a PDF's fillable form fields — lists every fillable field's name, type (text, checkbox, dropdown, radio, optionlist), current value and options so you know what to fill

Fill a PDF form's fields — sets text, checkbox, dropdown, radio and option-list values and returns the filled PDF as base64 in the first text item, optionally flattened so it can no longer be edited. Only the fields you name are changed; every other field keeps its value. To clear a field send null (or an empty string). The second text item is a JSON report: fieldsSet, fieldsNotSet (name and reason) and fieldsUntouched

Permanently redact areas of a PDF. Boxes are fractions (0 to 1) of the page as displayed, measured from the top-left corner, pages numbered from 0. Text characters, picture pixels, vector art and annotations under a box are removed from the file itself and an opaque black bar is drawn; everything outside the boxes stays real, selectable text in its original fonts. A page that cannot be edited exactly (for example a curved drawing partly under a box) is turned into a picture with the boxes painted black instead. Pages without boxes are not touched

Attempt to recover a damaged or corrupted PDF

Shrink a PDF from freedailypro. Default aims for about 50% smaller: tidies structure first (text untouched), then shrinks pictures only as much as needed. level: auto (default), medium, strong. targetFileSize (such as 2MB or 500KB) is the size to end at, for auto; default is half the original.

Shrink a scanned PDF from freedailypro by turning pages into pure black-and-white JBIG2 pictures, each page coded exactly as read (no letter is ever swapped; safe for contracts and numbers). Colour and shading are lost and text on converted pages is no longer selectable. A page is converted only when that makes it at least 10% smaller; other pages (for example real-text pages) are copied untouched. Errors if the PDF is unreadable, password-protected, over 100 pages, or if no smaller file results.

Shrink a scanned PDF from freedailypro to the smallest black-and-white file: JBIG2 symbol mode stores each letter shape once and reuses it across pages, typically 3x smaller than the lossless black-and-white file. Very rarely a letter can be swapped for a look-alike one (for example a 6 and a 8 in tiny print), so check important numbers in the original. Colour and shading are lost and text on converted pages is no longer selectable. A page is converted only when that makes it at least 10% smaller; other pages are copied untouched. Errors if the PDF is unreadable, password-protected, over 100 pages, or if no smaller file results.

Shrink a scanned PDF from freedailypro by turning pages into 100 dpi greyscale JPEG pictures: shading and photos are kept, colour is dropped, text on converted pages is no longer selectable. Larger than the black-and-white files but nothing is thresholded to pure black and white. A page is converted only when that makes it at least 10% smaller. Errors (nothing is returned) if the result would not be smaller than the original, or if the PDF is unreadable, password-protected or over 100 pages.

Shrink a PDF from freedailypro the gentle way (the site's Balanced mode): tidy the file, empty blank pages, and re-save the pictures inside at about 140 dpi. Text stays selectable; links, bookmarks, form fields and page sizes are kept. Returns the smaller file plus the levels applied. Errors if the PDF is unreadable, password-protected, over 100 pages, or if nothing gets smaller (for example a PDF that is already mostly text); in that case try pdf_compress_aggressive.

Shrink a PDF from freedailypro harder (the site's Aggressive mode): everything Balanced does, then pages become pictures in finer and finer steps (empty areas dropped, flat areas as plain fills, photos, text and small print at lower resolutions); a page is converted only when that is clearly smaller. Text on converted pages is no longer selectable and links and form fields on them are gone (textSelectable says which). Heavier than Balanced: it can take several seconds per page, and returns the best level finished so far (truncated: true) if the time budget runs out. Errors if the PDF is unreadable, password-protected, over 100 pages, or if nothing gets smaller.

Shrink a PDF from freedailypro as far as it will go (the site's Extreme mode): everything Aggressive does, then every page as 70 dpi greyscale and as pure black-and-white JBIG2 (exact, then with shared letter shapes), keeping the smallest. Colour and shading are lost and text is no longer selectable; very rarely a letter in tiny print can be swapped for a look-alike one in the symbol-mode result, so check important numbers in the original. Heavy: several seconds per page; returns the best level finished so far (truncated: true) if the time budget runs out. Errors if the PDF is unreadable, password-protected, over 100 pages, or if nothing gets smaller.

Shrink a PDF from freedailypro to a size you need, such as under 2 MB for an email or a portal (the site's File size mode). The same steps as Balanced, Aggressive and Extreme, gentlest first, stopping at the first one that fits. If the goal cannot be reached it finishes every allowed step and returns the smallest file with targetMet: false and limitReason. `limit` caps how far it may go (balanced keeps text selectable). Heavy at the stronger limits; returns the best level so far (truncated: true) if the time budget runs out. A PDF already under the goal is returned unchanged.

Resize an image from freedailypro with a width, a height or both (one alone keeps the aspect ratio). fit: fill (default, stretches to exactly width x height), contain (fits inside and pads with backgroundColor), cover (fills the box and crops the overflow around the centre), inside (fits within, keeps the ratio), outside (at least as large, keeps the ratio). withoutEnlargement never makes it bigger. Reads and writes JPEG, PNG, WebP, AVIF, GIF (animation kept), TIFF; the first text item is the picture as base64, the second a JSON note with its size

Crop an image to a region from freedailypro. unit fraction (default): x, y, w, h are 0 to 1 of the image; unit px: pixels. Reads and writes JPEG, PNG, WebP, AVIF, GIF (first frame), TIFF

Flip an image horizontally (mirror left to right) or vertically from freedailypro. Reads and writes JPEG, PNG, WebP, AVIF, GIF (first frame), TIFF

Rotate an image clockwise by 90, 180 or 270 degrees from freedailypro (no other angles). Reads and writes JPEG, PNG, WebP, AVIF, GIF (first frame), TIFF

Make an image file smaller from freedailypro: same format unless format is given (png, jpeg, webp, avif, gif, tiff), quality 1-100 for JPEG/WebP/AVIF (default 80), PNG stays lossless unless quality is below 100 (then a smaller 256-colour palette), metadata removed unless stripMetadata is false, optional maxWidth/maxHeight (never enlarges). If the file cannot be made smaller in its own format the original bytes come back unchanged and the note says so

Put a watermark on an image from freedailypro: text (drawn in Roboto, Latin/Greek/Cyrillic) or a watermark picture (watermarkBase64), at a position (center, top-left, top, top-right, left, right, bottom-left, bottom, bottom-right or tile), with opacity 0-1, size, margin and rotation. Reads and writes JPEG, PNG, WebP, AVIF, GIF (first frame), TIFF

Convert an image to PNG, JPEG, WebP, AVIF, GIF, TIFF, BMP or ICO from freedailypro, with optional quality, background colour, resize (fit modes), rotate/flip, grayscale, DPI and metadata controls. Inputs: JPEG, PNG, WebP, GIF (animated kept for GIF/WebP output), AVIF, TIFF, SVG, BMP. HEIC is not supported. Returns the converted file as base64 text.

Convert a video between formats (mp4/mp4-web/webm/mov)

Trim a video to a time range -- stream-copy, cuts snap to the nearest keyframe

Merge multiple videos into one -- requires matching codec/resolution/frame rate across inputs

Extract a video frame as a JPEG thumbnail

Convert a video to an animated GIF -- two-pass palette encoding

Burn SRT subtitles permanently into a video

Compress a video toward a target file size (targetFileSize such as 25MB; default half the original) -- two-pass encode, a floor bitrate is enforced below which quality degrades too much to be worth watching

Convert audio between formats (mp3/wav/ogg/m4a/flac)

Trim audio to a time range

Merge multiple audio files into one

Compress audio toward a target file size (targetFileSize such as "2MB"; default half the original)

Remove silence throughout an audio file

Get the text of every slide in a PowerPoint (.pptx) from freedailypro: titles, bullets (with their level) and tables, optionally with the speaker notes. format: txt (default), md or json (json returns slides with title, paragraphs, tables and notes, easiest to process). Hidden slides are skipped unless includeHidden is true. Charts and diagrams are not read (counted in the output instead). Errors when the deck has no text at all (a deck made only of pictures).

Get the speaker notes of a PowerPoint (.pptx) from freedailypro, slide by slide. format: txt (default), md, or docx (a Word file, returned as base64). Hidden slides' notes are skipped unless includeHidden is true. Errors when the deck has no speaker notes.

Pull the pictures out of a PowerPoint (.pptx) from freedailypro as a ZIP (returned as base64), each file exactly as stored in the deck and named by slide, for example slide02_image-2-1.jpeg. Pictures that only the slide design uses (a logo on the master) are left out unless includeTemplatePictures is true; pictures on hidden slides are left out unless includeHidden is true. Errors when there are none.

Strip what you do not want to share from a PowerPoint (.pptx) from freedailypro, and get a clean .pptx back (base64): speaker notes, comments, hidden slides, author and company details with the revision list, and the stored preview picture. All of those are on by default; documentProperties (title, subject, keywords) and customProperties (labels and tags) are off by default. Slide content, layout and formatting are untouched, and parts only the removed slides used are dropped. Errors if every slide is hidden and hiddenSlides is on.

Compress a PowerPoint (.pptx) from freedailypro at the Default level, the sharpest: pictures are kept up to 220 dpi at JPEG quality 82, large photos get smaller, and nothing is converted from PNG to JPEG. Only pictures are re-saved (JPEG, PNG, BMP); text, layouts, charts, animations, audio and video are left exactly as they are, so the deck stays fully editable. Returns the smaller .pptx as base64 plus originalBytes, outputBytes, reductionPercent and the pictures changed. Errors with a plain reason (422) when nothing can get smaller, for example a deck with no pictures.

Compress a PowerPoint (.pptx) from freedailypro at the Medium level: pictures up to 150 dpi at JPEG quality 72, and opaque PNG photos are re-saved as JPEG when that is under half the size. Good for email. Only pictures are re-saved (JPEG, PNG, BMP); text, layouts, charts, animations, audio and video are left exactly as they are, so the deck stays fully editable. Returns the smaller .pptx as base64 plus originalBytes, outputBytes, reductionPercent and the pictures changed. Errors with a plain reason (422) when nothing can get smaller, for example a deck with no pictures.

Compress a PowerPoint (.pptx) from freedailypro at the Strong level, the smallest of the three: pictures up to 110 dpi at JPEG quality 58. Fine on screen, soft in print. Only pictures are re-saved (JPEG, PNG, BMP); text, layouts, charts, animations, audio and video are left exactly as they are, so the deck stays fully editable. Returns the smaller .pptx as base64 plus originalBytes, outputBytes, reductionPercent and the pictures changed. Errors with a plain reason (422) when nothing can get smaller, for example a deck with no pictures.

Compress a PowerPoint (.pptx) from freedailypro to a size you need, such as under 10 MB for an email or an upload form. Runs from the sharpest picture setting to the coarsest and returns the sharpest result that fits targetSize, with targetMet: true. If it cannot fit, you get the smallest file it can make with targetMet: false and a note. A deck already at or under the target is returned unchanged. Only pictures are re-saved (JPEG, PNG, BMP); text, layouts, charts, animations, audio and video are left exactly as they are, so the deck stays fully editable. Returns the smaller .pptx as base64 plus originalBytes, outputBytes, reductionPercent and the pictures changed. Errors with a plain reason (422) when nothing can get smaller, for example a deck with no pictures.

Split a PowerPoint (.pptx) from freedailypro into several presentations, returned as ONE ZIP (base64) of .pptx files, each a complete editable deck keeping its own slides' notes, pictures, charts and tables. mode: each (one file per slide; default), every (every N slides, give every), or range (ranges such as '1-3,5,8-': one file per range, or one file with all of them when rangesAsFiles is false). At most 100 files. Errors name the slide numbers that do not exist.

Reorder, delete and duplicate the slides of a PowerPoint (.pptx) from freedailypro, returning a new editable .pptx (base64); the slide master, layouts and theme stay as they were and every slide keeps its notes, pictures, charts and tables. order: the final order as 1-based slide numbers, for example [3,1,2] (a number twice makes a copy). remove: slides to delete. duplicate: slides to copy, the copy placed right after the original. removeHidden: delete every hidden slide. Slide numbers always refer to the ORIGINAL deck. Errors when a number does not exist or every slide would be removed.

Merge two or more PowerPoint (.pptx) files from freedailypro into one editable presentation (base64), slides in the order the files are given. Each deck keeps its own master, layouts and theme (several masters in one file), so slides keep the look they came with; set useFirstDesign true to put later decks on the first deck's layouts when they match by name. All decks must have the SAME slide size: otherwise it errors (422) naming the decks and their sizes, so fix the size first (in PowerPoint: Design, Slide Size). Comments of the second and later decks are left out. Up to 10 decks and 100 MB in all.

Turn Markdown or a plain outline into an editable PowerPoint (.pptx, base64) from freedailypro, with real title and body placeholders (so Outline view, the slide master and accessibility checks work). `# Title` makes the title slide (a short line under it is the subtitle), `## Heading` a new slide, `### Heading` a bold sub-heading, `- item` / `1. item` bullets (indent two spaces for sub-bullets), `| a | b |` tables, `Note: text` speaker notes, `---` ends a slide, **bold**, *italic*, `code` and [links](https://example.com) work. Pictures given by web address are not fetched (reported in warnings); use json_to_pptx to put pictures in. mode outline reads an indented outline instead (first line = deck title). Themes: clean, dark, corporate, warm, minimal, or a brand colour and fonts.

Build an editable PowerPoint (.pptx, base64) from a JSON description of the slides, from freedailypro. Each slide takes title, subtitle, bullets (strings, or {text, bullets:[...]} for sub-bullets; set numbered true for 1. 2. 3.), text (a paragraph or list of paragraphs), table ({header:[...], rows:[[...]]}), image ({data: base64 or data: URI of a PNG, JPEG or GIF, alt: description}) and notes (speaker notes). A slide with only a title (and subtitle) is a cover when it is first or has a subtitle; layout "title" or "content" forces it. With an image the text sits on the left and the picture on the right, keeping its shape; an image alone is centred. Bullets, text and subtitle accept **bold**, *italic*, `code` and [links](https://example.com); titles and table cells are plain text. Pictures are never fetched from a URL: send base64, and give each an alt text (a warning says when it is missing). Limits: 200 slides, 40 bullets per slide, tables of 60 rows and 12 columns (a table over 14 rows will run off the slide: warning), pictures 8 MB each and 24 MB in all. Themes clean, dark, corporate, warm, minimal, or brand {color, headingFont, bodyFont, dark}. Returns fileName, base64, slides and warnings; invalid input errors name the field, for example slides[2].bullets[1] must be text.

Turn a CSV file into an editable PowerPoint (.pptx, base64) of table slides from freedailypro: a cover slide, then the header and up to rowsPerSlide (default 12, max 40) rows on each slide, titled 'Title (1 of 3)'. The first row holds the column names unless header is false. The delimiter (comma, semicolon or tab) is found from the first line. At most 12 columns and 200 slides; cells are kept as plain text. Themes clean, dark, corporate, warm, minimal, or a brand.

Find and replace text across every slide of a PowerPoint (.pptx) from freedailypro, and get the edited .pptx back (base64). Matches inside a paragraph are replaced even when PowerPoint split the words into several runs; the formatting of the first run is kept. Speaker notes are searched too (includeNotes, default true); the slide master and layouts only when includeTemplate is true. Errors with 422 when nothing matches, so a wrong spelling is noticed.

List every font a PowerPoint (.pptx) from freedailypro uses, as JSON: name, how many places use it, which slides, whether the master/layouts/theme use it, whether it is the theme's heading or body font and whether it is embedded. Use it before pptx_replace_fonts.

Swap fonts across a PowerPoint (.pptx) from freedailypro and get the new .pptx (base64): slides, notes, layouts, masters, the theme's heading and body fonts, charts and SmartArt. mapping is {"Old font": "New font"}. Embedded copies of replaced fonts are removed. Errors (422) when none of the named fonts is used. Text is not resized, so a wider font can make a line wrap.

Add slide numbers to a PowerPoint (.pptx) from freedailypro, or remove them, and get the new .pptx (base64). The numbers are real slide-number fields, so they follow when slides move. Slides that already have a number are left alone. 'of-total' writes the total as plain text (PowerPoint has no total field). mode remove takes off the numbers the slides themselves carry (not those on the master).

Stamp a text watermark (such as DRAFT or CONFIDENTIAL) or a picture on the slides of a PowerPoint (.pptx) from freedailypro, or remove the watermarks this tool made, and get the new .pptx (base64). Give text, or pictureBase64 (PNG or JPEG) for a picture. It sits behind the slide content by default.

Change the slide size of a PowerPoint (.pptx) from freedailypro and scale the content to match, returning the new .pptx (base64). preset 16x9, 4x3, 16x10, a4 or letter, or width and height with a unit. mode fit (default) keeps the shape of the content and centres it; fill covers the new area; stretch changes the shape. Fonts, line widths and spacing scale with the content unless scaleText is false. The result lists how many shapes now reach outside the slide. Errors (422) when the slides are already that size.

Get the data behind every chart of a PowerPoint (.pptx) from freedailypro: format xlsx (default; one workbook, a sheet per chart, base64), csv (a ZIP of CSV files, base64; workbooks true also adds each chart's own embedded workbook) or json (each chart's slide, title, type and table). Charts pasted as pictures have no data; errors (422) when the deck has no real charts.

Check a PowerPoint (.pptx) from freedailypro for accessibility problems and get a JSON report (or CSV): pictures and charts without alt text or with a file name as alt text, slides with no title or an empty or duplicate title, text under 12 points, table header rows, merged cells, vague link text and reading-order problems. Each issue has the slide, severity (error, warning, tip) and a plain message. The check reports only; it changes nothing.

Try to repair a damaged PowerPoint (.pptx) from freedailypro that PowerPoint reports as needing repair or will not open, and get a new .pptx (base64) plus what was fixed and what was lost. Mends a missing or wrong file list, a missing or inconsistent slide list, dead links to pictures, charts and layouts, duplicate slide ids and a damaged zip index; pieces that cannot be saved are dropped and listed. A healthy file is returned unchanged with changed false. Cannot open password-protected files or old .ppt files.

Black out sensitive text in a PowerPoint (.pptx) from freedailypro and get the redacted .pptx (base64). Matches are replaced by block characters in the file's own text (not covered), on slides, notes, the master and layouts, charts, SmartArt, comments, alt text and link targets. presets: email, phone, ssn, card, url, ip, money, date; plus terms (exact words), regexes, imageSlides ('all' or slide numbers: pictures replaced by a black stand-in) and imageByAlt. stripNotes, stripComments and stripMetadata remove those entirely. The result is read again and any remaining match is reported (remaining, remainingWhere). Text inside pictures, video and audio cannot be found; warnings say what could not be checked. A deck with no match is returned unchanged with changed false.

Turn a PowerPoint (.pptx) from freedailypro into ONE self-contained HTML file (returned as text): the slides as readable text with their pictures inlined, arrow-key navigation, a grid (G) and optional speaker notes (N). No external files or scripts. Charts, SmartArt, video, audio and animations are not carried over (notCarried lists them). Speaker notes are off unless includeNotes is true; hidden slides are left out unless includeHidden is true.

Turn a PowerPoint (.pptx) from freedailypro into a .potx template (base64) and optionally change its theme: colors is {dk1, lt1, dk2, lt2, accent1..accent6, hlink, folHlink} as six-digit hex, plus headingFont, bodyFont and the theme name. keepSlides all, first or none. format pptx gives a re-themed deck instead. Shapes with their own fixed colour or font do not follow the theme; fixedColorShapes and fixedFontRuns count them. The .potx has been checked in LibreOffice, not in desktop PowerPoint.
