All 74 PDF tools — free, private, no sign-up
Everything happens on your device. Nothing goes outside. Tools marked On-device run in your browser; tools marked API · MCP run free on our servers under the same privacy rules — files deleted within an hour, content never logged.
Organize PDF
Merge, split, rotate, reorder and reshape PDF pages — the everyday page surgery, done in your browser.
Merge PDFs On-deviceCombine multiple PDF files into one, in upload order.Split PDF On-deviceSplit a PDF by page ranges (ZIP of PDFs) or one PDF per page.Rotate pages On-deviceRotate pages by 90, 180 or 270 degrees.Delete pages On-deviceRemove the selected pages from a PDF.Extract pages On-deviceCreate a new PDF containing only the selected pages.Reorder pages On-deviceRearrange pages into the given 1-based order (a permutation of all pages).Split PDF by file size API · MCPSplit a PDF into parts that each stay under a byte limit (ZIP of PDFs).Insert blank page On-deviceInsert one or more blank pages at a position (default: at the end).Crop pages On-deviceCrop pages to an absolute rect [x0, y0, x1, y1] in points, or by margins from each edge.Resize / scale pages On-deviceReformat every page to a paper size (or explicit dimensions), scaling content to fit, centred.Overlay PDF On-deviceStamp the pages of a second PDF ON TOP of the first (files: base PDF, stamp PDF; stamp pages cycle).Underlay PDF On-devicePlace the pages of a second PDF UNDERNEATH the first (files: base PDF, background PDF; background pages cycle).Reverse page order On-deviceReverse the order of all pages in the PDF.N-up imposition On-deviceTile multiple source pages onto each output sheet in a cols x rows grid.Split by bookmarks On-deviceSplit a PDF into one file per bookmark/outline section (ZIP).Split by text On-deviceStart a new output file at every page whose text contains the given string or matches the given regex (ZIP).Interleave two PDFs On-deviceAlternate pages from two PDFs (e.g. merging separately scanned odd/even pages). Optionally reverse the second file's page order first.Remove blank pages On-deviceDrop pages that carry no text and (nearly) no ink. If every page is blank, page 1 is kept.
Convert to PDF
Turn images, documents and web content into clean PDFs.
Images to PDF On-deviceCombine images (JPG/PNG/WebP/TIFF/GIF) into a single PDF.HTML to PDF API · MCPRender an HTML document to PDF. Fully offline: external resources (images, stylesheets, scripts) are never fetched — inline everything you need.Markdown to PDF API · MCPRender a Markdown document (GitHub-flavoured) to a typeset PDF.Text to PDF On-deviceRender a plain-text file to a PDF (monospaced, line-wrapped).Office document to PDF API · MCPConvert Word/Excel/PowerPoint/OpenDocument files (docx, xlsx, pptx, odt, ods, odp, doc, xls, ppt, rtf) to PDF via the LibreOffice backend.EPUB to PDF API · MCPConvert an EPUB ebook to a typeset PDF (text-focused: chapter text and headings in spine order; embedded images are not rendered).HEIC to PDF On-deviceConvert HEIC/HEIF photos (and other images) to a PDF, one page per image frame. Requires the libheif decode backend; without it the op reports backend_unavailable.
Convert from PDF
Turn PDFs into Word, HTML, text, Markdown, images and structured data your tools and agents can use.
PDF to Word (DOCX) API · MCPConvert a PDF to an editable Word document. Text-based conversion: paragraphs and headings are reconstructed from the text layer; exact layout, tables and images are not preserved.PDF to text On-deviceExtract plain text, one form-feed separated section per page.PDF to images On-deviceRender each page to an image (ZIP).PDF to Markdown On-deviceExtract text as Markdown, with headings inferred from font sizes.Extract text as JSON On-devicePer-page structured text: blocks with bounding boxes, ready for agents/LLMs.PDF to HTML On-deviceConvert a PDF to a single HTML document, one section per page, preserving positioned text.PDF tables to CSV API · MCPExtract every detected table in the PDF as a CSV file (ZIP when there are several).PDF to TIFF API · MCPRender all pages into a single multi-page TIFF file.PDF to WebP On-deviceRender each page to a WebP image (ZIP).PDF to EPUB On-deviceConvert a PDF's text into an EPUB 3 ebook, chaptered by level-1 bookmarks when present. Honest scope: text-based conversion — original layout, fonts and images are not preserved.PDF to XML On-deviceMachine-readable XML dump: metadata, per-page text and per-word bounding boxes.
Optimize PDF
Compress, repair, archive and slim down PDFs without wrecking them.
Compress PDF On-deviceReduce file size with Ghostscript. Presets: light (printer quality), medium (ebook), heavy (screen, smallest).Repair PDF API · MCPRewrite and repair a damaged PDF with qpdf.Flatten PDF On-deviceBake form fields and annotations into the page content.Convert to PDF/A API · MCPConvert a PDF to the PDF/A archival standard with Ghostscript.Linearize PDF API · MCPRewrite a PDF linearized ('Fast Web View') so first pages display before the whole file downloads.Optimize images in PDF API · MCPDownscale and recompress oversized embedded images, and drop duplicate image data.Deskew pages API · MCPDetect and correct small scan skew (up to ±5°) on each page using a projection-profile search.Convert to grayscale API · MCPConvert all colors in the PDF to grayscale with Ghostscript.
Protect & sign
Passwords, permissions, redaction, sanitizing, signatures — and stripping the metadata that tracks you.
Encrypt PDF API · MCPProtect a PDF with a user password (AES-256).Unlock PDF API · MCPRemove password protection (the current password is required).Strip AI metadata & provenance On-deviceRemove AI-generation provenance and identifying metadata from a PDF or image (JPEG/PNG/WebP): C2PA Content Credentials, XMP/EXIF/IPTC AI markers (incl. IPTC DigitalSourceType trainedAlgorithmicMedia), generator Software/Creator tags, EXIF GPS and device data. Metadata only — content and pixels are never modified, image pixels are not re-encoded, and pixel-embedded invisible watermarks (e.g. SynthID) are NOT removed: they live in the image data itself, not in metadata. The result reports exactly what was found and removed, by category.Sanitize PDF On-deviceStrip metadata (incl. XMP), JavaScript, embedded files/attachments, document actions and link/file actions — the safe-to-share version of a PDF.Sign PDF (visual signature) On-devicePlace a visual signature on a PDF: upload the signature image as the SECOND file, or let the signer name be typeset. A self-signed certificate (SHA-256 fingerprint) is generated and recorded in the document metadata. This is an electronic signature stamp + certificate record — not a qualified/PKI document signature.Set PDF permissions API · MCPEncrypt a PDF with an owner password and fine-grained permissions (print, copy, modify, annotate, ...).Redact PDF API · MCPTRUE redaction: content under the regions is removed from the file (not just covered). Modes: explicit regions, literal texts, and/or PII patterns (emails, SSNs, payment-card numbers — Luhn-checked).Sign with certificate (PAdES) API · MCPApply a real cryptographic PAdES signature with your PKCS#12 certificate (.p12/.pfx, uploaded as the second file). Verifiable in any conforming PDF reader. Note: the certificate password is a job parameter, handled exactly like the encrypt/decrypt passwords.
Edit & mark up
Watermarks, page numbers, headers, Bates stamps, form filling and annotations.
Watermark PDF On-deviceStamp diagonal text across every page.Add page numbers On-deviceStamp page numbers, format 'Page {n} of {total}'.Add header & footer On-deviceStamp a header and/or footer line on every page. {page} and {total} placeholders are substituted per page.Bates numbering On-deviceStamp sequential Bates numbers (prefix + zero-padded counter) on every page.Fill PDF form On-deviceFill AcroForm fields by name. Values: strings for text fields, true/false for checkboxes, numbers are stringified.Read form fields On-deviceList all AcroForm fields with names, types, current values and locations (JSON).Add text to PDF On-deviceWrite text at an exact position (points, top-left origin) on one page.Add image to PDF On-devicePlace an uploaded image (SECOND file) onto a page of the PDF (FIRST file) at an exact position.Highlight text / regions API · MCPAdd highlight annotations: every occurrence of a search text, and/or explicit rects per page.Remove annotations On-deviceDelete annotations (highlights, notes, stamps, links, …). Form field widgets are kept unless requested.Create bookmarks API · MCPAdd a PDF outline from a supplied list of {level, title, page} entries, or auto-detect headings from larger-than-body text.Edit metadata On-deviceSet document information fields (title, author, subject, keywords, creator, producer). Pass an empty string to clear a field.Create form fields On-deviceAdd fillable form fields (text, checkbox, dropdown) at given pages and rectangles. Pairs with fill_form and read_form_fields.
Extract & OCR
Pull text, tables, images, bookmarks and attachments out of PDFs — the agent-first toolbox.
OCR — searchable PDF API · MCPMake a scanned PDF searchable: pages without a text layer are OCR'd with Tesseract and gain an invisible text layer; pages that already have text are passed through and reported as skipped.PDF info & metadata On-devicePage count, page sizes, metadata, encryption status as JSON.Extract images API · MCPPull all embedded images out of a PDF (ZIP, original formats).Extract tables (JSON + CSV) API · MCPDetect tables and return them as tables.json plus one CSV per table (ZIP).Extract bookmarks / TOC On-deviceReturn the document outline as JSON: level, title, target page.Extract attachments On-devicePull all embedded file attachments out of the PDF (ZIP).Extract words with bounding boxes On-devicePer-word text extraction with exact bounding boxes (points), grouped by page — agent/LLM ready.OCR to text On-deviceOCR a scanned PDF to plain text. Pages that already carry a text layer contribute that text directly (no OCR needed).Compare PDFs API · MCPPage-level diff of two PDFs: which pages are identical, modified (with a unified text diff and similarity score), added or removed. Returns report.json, optionally with rendered diff images highlighting changed pixels.
