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.
01Organize PDF
Merge, split, rotate, reorder and reshape PDF pages — the everyday page surgery, done in your browser.
On-deviceMerge PDFsCombine multiple PDF files into one, in upload order.On-deviceSplit PDFSplit a PDF by page ranges (ZIP of PDFs) or one PDF per page.On-deviceRotate pagesRotate pages by 90, 180 or 270 degrees.On-deviceDelete pagesRemove the selected pages from a PDF.On-deviceExtract pagesCreate a new PDF containing only the selected pages.On-deviceReorder pagesRearrange pages into the given 1-based order (a permutation of all pages).API · MCPSplit PDF by file sizeSplit a PDF into parts that each stay under a byte limit (ZIP of PDFs).On-deviceInsert blank pageInsert one or more blank pages at a position (default: at the end).On-deviceCrop pagesCrop pages to an absolute rect [x0, y0, x1, y1] in points, or by margins from each edge.On-deviceResize / scale pagesReformat every page to a paper size (or explicit dimensions), scaling content to fit, centred.On-deviceOverlay PDFStamp the pages of a second PDF ON TOP of the first (files: base PDF, stamp PDF; stamp pages cycle).On-deviceUnderlay PDFPlace the pages of a second PDF UNDERNEATH the first (files: base PDF, background PDF; background pages cycle).On-deviceReverse page orderReverse the order of all pages in the PDF.On-deviceN-up impositionTile multiple source pages onto each output sheet in a cols x rows grid.On-deviceSplit by bookmarksSplit a PDF into one file per bookmark/outline section (ZIP).On-deviceSplit by textStart a new output file at every page whose text contains the given string or matches the given regex (ZIP).On-deviceInterleave two PDFsAlternate pages from two PDFs (e.g. merging separately scanned odd/even pages). Optionally reverse the second file's page order first.On-deviceRemove blank pagesDrop pages that carry no text and (nearly) no ink. If every page is blank, page 1 is kept.
02Convert to PDF
Turn images, documents and web content into clean PDFs.
On-deviceImages to PDFCombine images (JPG/PNG/WebP/TIFF/GIF) into a single PDF.API · MCPHTML to PDFRender an HTML document to PDF. Fully offline: external resources (images, stylesheets, scripts) are never fetched — inline everything you need.API · MCPMarkdown to PDFRender a Markdown document (GitHub-flavoured) to a typeset PDF.On-deviceText to PDFRender a plain-text file to a PDF (monospaced, line-wrapped).API · MCPOffice document to PDFConvert Word/Excel/PowerPoint/OpenDocument files (docx, xlsx, pptx, odt, ods, odp, doc, xls, ppt, rtf) to PDF via the LibreOffice backend.API · MCPEPUB to PDFConvert an EPUB ebook to a typeset PDF (text-focused: chapter text and headings in spine order; embedded images are not rendered).On-deviceHEIC to PDFConvert 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.
03Convert from PDF
Turn PDFs into Word, HTML, text, Markdown, images and structured data your tools and agents can use.
API · MCPPDF to Word (DOCX)Convert 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.On-devicePDF to textExtract plain text, one form-feed separated section per page.On-devicePDF to imagesRender each page to an image (ZIP).On-devicePDF to MarkdownExtract text as Markdown, with headings inferred from font sizes.On-deviceExtract text as JSONPer-page structured text: blocks with bounding boxes, ready for agents/LLMs.On-devicePDF to HTMLConvert a PDF to a single HTML document, one section per page, preserving positioned text.API · MCPPDF tables to CSVExtract every detected table in the PDF as a CSV file (ZIP when there are several).API · MCPPDF to TIFFRender all pages into a single multi-page TIFF file.On-devicePDF to WebPRender each page to a WebP image (ZIP).On-devicePDF to EPUBConvert 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.On-devicePDF to XMLMachine-readable XML dump: metadata, per-page text and per-word bounding boxes.
04Optimize PDF
Compress, repair, archive and slim down PDFs without wrecking them.
On-deviceCompress PDFReduce file size with Ghostscript. Presets: light (printer quality), medium (ebook), heavy (screen, smallest).API · MCPRepair PDFRewrite and repair a damaged PDF with qpdf.On-deviceFlatten PDFBake form fields and annotations into the page content.API · MCPConvert to PDF/AConvert a PDF to the PDF/A archival standard with Ghostscript.API · MCPLinearize PDFRewrite a PDF linearized ('Fast Web View') so first pages display before the whole file downloads.API · MCPOptimize images in PDFDownscale and recompress oversized embedded images, and drop duplicate image data.API · MCPDeskew pagesDetect and correct small scan skew (up to ±5°) on each page using a projection-profile search.API · MCPConvert to grayscaleConvert all colors in the PDF to grayscale with Ghostscript.
05Protect & sign
Passwords, permissions, redaction, sanitizing, signatures — and stripping the metadata that tracks you.
API · MCPEncrypt PDFProtect a PDF with a user password (AES-256).API · MCPUnlock PDFRemove password protection (the current password is required).On-deviceStrip AI metadata & provenanceRemove 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.On-deviceSanitize PDFStrip metadata (incl. XMP), JavaScript, embedded files/attachments, document actions and link/file actions — the safe-to-share version of a PDF.On-deviceSign PDF (visual signature)Place 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.API · MCPSet PDF permissionsEncrypt a PDF with an owner password and fine-grained permissions (print, copy, modify, annotate, ...).API · MCPRedact PDFTRUE 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).API · MCPSign with certificate (PAdES)Apply 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.
06Edit & mark up
Watermarks, page numbers, headers, Bates stamps, form filling and annotations.
On-deviceWatermark PDFStamp diagonal text across every page.On-deviceAdd page numbersStamp page numbers, format 'Page {n} of {total}'.On-deviceAdd header & footerStamp a header and/or footer line on every page. {page} and {total} placeholders are substituted per page.On-deviceBates numberingStamp sequential Bates numbers (prefix + zero-padded counter) on every page.On-deviceFill PDF formFill AcroForm fields by name. Values: strings for text fields, true/false for checkboxes, numbers are stringified.On-deviceRead form fieldsList all AcroForm fields with names, types, current values and locations (JSON).On-deviceAdd text to PDFWrite text at an exact position (points, top-left origin) on one page.On-deviceAdd image to PDFPlace an uploaded image (SECOND file) onto a page of the PDF (FIRST file) at an exact position.API · MCPHighlight text / regionsAdd highlight annotations: every occurrence of a search text, and/or explicit rects per page.On-deviceRemove annotationsDelete annotations (highlights, notes, stamps, links, …). Form field widgets are kept unless requested.API · MCPCreate bookmarksAdd a PDF outline from a supplied list of {level, title, page} entries, or auto-detect headings from larger-than-body text.On-deviceEdit metadataSet document information fields (title, author, subject, keywords, creator, producer). Pass an empty string to clear a field.On-deviceCreate form fieldsAdd fillable form fields (text, checkbox, dropdown) at given pages and rectangles. Pairs with fill_form and read_form_fields.
07Extract & OCR
Pull text, tables, images, bookmarks and attachments out of PDFs — the agent-first toolbox.
API · MCPOCR — searchable PDFMake 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.On-devicePDF info & metadataPage count, page sizes, metadata, encryption status as JSON.API · MCPExtract imagesPull all embedded images out of a PDF (ZIP, original formats).API · MCPExtract tables (JSON + CSV)Detect tables and return them as tables.json plus one CSV per table (ZIP).On-deviceExtract bookmarks / TOCReturn the document outline as JSON: level, title, target page.On-deviceExtract attachmentsPull all embedded file attachments out of the PDF (ZIP).On-deviceExtract words with bounding boxesPer-word text extraction with exact bounding boxes (points), grouped by page — agent/LLM ready.On-deviceOCR to textOCR a scanned PDF to plain text. Pages that already carry a text layer contribute that text directly (no OCR needed).API · MCPCompare PDFsPage-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.
