About these PDF tools

A PDF is a container, so most jobs here move parts of the document rather than draw it again. Pages are copied from one file to another with their text, vector art and fonts intact. That keeps the result sharp and selectable, and it is far quicker than turning pages into pictures.

Two kinds of job are harder in a browser. Turning a PDF into a Word or Excel file means rebuilding a layout the format never recorded, so the result depends on how the document was made. A scan holds no text at all until it has been read by OCR. Both are possible, and each tool says what it can and cannot do on its own page.

Reading happens with pdf.js and writing with pdf-lib, both compiled for the browser. Where a page turns out to be a picture, the text is recovered with OCR, and that model is fetched only when a scan actually turns up.

Engine
pdf-lib and pdf.js in the page, with OCR where it is needed.
File size
No cap. A 1,000-page document works; it just takes longer.
Encryption
A password-protected file must be unlocked before anything reads it.
Signatures
Editing a signed PDF breaks the signature. That is the format, not us.

Frequently asked questions

Are my PDFs uploaded?
No. They are read and rewritten in this tab, so contracts, medical letters and bank statements never leave your device. There is no copy on a server to expire or leak.
Is there a page or size limit?
None that we set. Your browser holds the document in memory, so a very large file can run a tab out of room. A phone gives up sooner than a laptop.
Can I merge password-protected files?
Not while they are locked. Unlock them first with the password you already have, then merge. We cannot open a file you do not have the password for.
Does converting to Word keep the layout?
It gets close on a simple document. A PDF does not record columns, tables or headings as such, so the converter works them out, and a complicated page needs tidying afterwards.
Can I get the text out of a scan?
Yes. If a page holds no text, it is rendered and read by OCR in the page. The model downloads once, and only when a scan turns up.
Do you add a watermark?
No. Nothing is stamped on your document, at any size or count.
