All PDF tools
17 tools and a full editor that work on the file in this browser tab. You don’t need an account or an install.
Edit & review
Edit & annotateHighlight, underline or strike through text, add sticky notes with replies, stamps, drawings, text boxes, shapes and images, and fill in form fields. Downloads keep comments editable as standard PDF comments, or flatten them. Undo anything.Fill & signDraw, type or upload a signature or initials, and add dates, text, checkmarks and stamps. On a form without fields, Find fields looks for blanks, boxes and signature lines in this tab; review them, then make the PDF fillable. Fill in my details fills matching fields from details saved in this browser, and you can flatten the form when you download.Compare PDFsPut two versions side by side. Inserted, deleted and changed words are highlighted on both, with a change list you can click through and a pixel overlay for scans and drawings.
Organize
Merge PDFCombine two or more PDFs into one. Drag files to set the order, or sort by name.Split PDFPick pages, type ranges like 1-3, 8-, or split every N pages or into single pages. Several files download as one ZIP.Organize pagesDrag pages into order, rotate, duplicate or delete them, add blank pages, and insert pages from another PDF.Add page numbersAdd 1, Page 1, 1 / N or Page 1 of N at any of six positions. Choose the start number and skip the cover page.Bates numberingNumber every page of several files in one sequence, with a prefix, start number, digits and suffix. Add header and footer text on the left, center or right, with the page number, page count, date or file name. Files download as one ZIP with a CSV of each file’s first and last number.Batch processBuild a recipe from steps such as remove hidden data, redact, compress, watermark, page numbers, Bates numbers, headers and footers, rotate, flatten form fields and protect, then run it on many PDFs. Files are processed one at a time, and one that fails doesn’t stop the rest. Recipes are saved in this browser. Results download as one ZIP.
Convert & compress
Compress PDFRe-encodes large embedded images as JPEG at one of three levels. Text and vector graphics are copied unchanged, and if the result isn’t smaller you get the original back.PDF to WordRebuilds paragraphs and headings from the PDF’s text and saves a Word file, Markdown or plain text, in your browser. Scanned pages need OCR, which you can turn on here. Tables and complex layouts may need tidying by hand.OCR PDFAdds an invisible text layer to scanned PDFs and photos so you can search, select and copy the text. 26 languages. The page images aren’t changed.Images to PDFTurn photos and scans into one PDF on A4, Letter or image-sized pages. Phone photos are rotated using their EXIF orientation.PDF to imagesExport every page, or a range, as PNG, JPG or WebP at 72, 150 or 300 dpi. Several images download as one ZIP.
Security
Redact PDFMark text by search, by pattern (emails, phone numbers, card numbers and more) or by drawing boxes. What’s under each box is deleted from the file, not covered up. Then the new file is checked: its text is re-read, and the area under each box is drawn again without the box and checked to be blank. A page where something still shows is redrawn as an image with the boxes burned in.Sanitize PDFRemoves what a PDF carries besides its pages: metadata, JavaScript and automatic actions, attached files, hidden layers, page thumbnails and data that editing apps keep for themselves. Invisible text is removed too, except the text OCR adds to make scans searchable. Links, form fields and comments stay unless you choose to remove them. A report lists what was removed and what wasn’t found.Protect PDFEncrypt with AES-256 so the PDF needs a password to open. Optionally block printing, copying or editing with a second password.Unlock PDFRemove the open password from a PDF you have the password for. Printing, copying and editing restrictions stay unless you also have the permissions password.WatermarkStamp text or an image on every page or a range. Set opacity, rotation from −90° to 90°, and a centered or tiled layout.
What runs where
Many PDF websites upload your file to their servers before they work on it. Here, the PDF engine runs in your browser instead: pdf.js renders pages, pdf-lib edits and encrypts, and Tesseract reads scans. Only My documents sends files out, and only the ones you choose to save.
