All the PDF Tools
you need

Three tools that read the document instead of moving its pages. Chat PDF answers questions about it, Summarise returns points each ending in a literal quote you can check, and Translate rebuilds the layout in another language. All three send the extracted text to DeepSeek, outside the European Economic Area, and each says so on screen before it sends anything. Three questions a day without an account, five with a free one.

Into PDF from Word, Excel, PowerPoint, images, HTML or a phone photo; out of PDF into Word, Excel, PowerPoint, images, text or Markdown. Going in is usually faithful. Coming out is where expectations need managing: a PDF has no paragraphs inside, only positioned glyphs, so a conversion rebuilds structure by inference. Text-heavy documents come back well; complex layouts come back approximately.

Write on the page, sign it, stamp a watermark, number the pages, crop the margins or black out what should not be read. Redaction here removes the underlying text, it does not draw a rectangle over it. Nothing in this family leaves your browser.

Merge, split, reorder, rotate, extract or delete pages. This is the family that works on the document as a stack of sheets, and it is the fastest: pdf-lib rewrites the page tree in your browser without re-encoding anything, so a 400-page file takes about as long as a 4-page one. One document at a time, except Merge.

Compression with one lever, a quality slider, and repair for a file that will not open. Compression runs on our server with Ghostscript because a browser cannot re-encode images at that level; repair runs there too, with pikepdf, qpdf and mutool taking turns. Both upload over HTTPS and both delete the file within the hour.

Put a password on a document or take one off a document you can already open. Protection encrypts with AES-256 and denies editing, annotating, form filling and copying, while leaving printing allowed; you do not choose those permissions, and the open password and owner password are the same one, so a determined reader can work around them. Unlocking needs the password: nothing here breaks encryption.
