About these PDF tools

A PDF is a container, so most jobs here move parts of the document without drawing 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.

Scans are the harder case. A scanned page holds no text until OCR reads it, and OCR makes a good guess, not a copy. PDF to Text reads scanned pages in English and marks which pages it read that way.

pdf.js reads the documents and pdf-lib writes them, both running in your browser. The OCR model downloads only when a scanned page turns up.

Engine
pdf-lib and pdf.js in the page, with OCR where it is needed.
File size
No fixed cap. The document has to fit in memory.
Encryption
A password-protected file must be unlocked before anything reads it.
Signatures
Changing a signed PDF breaks its signature, because the signed bytes change.

Frequently asked questions

Are my PDFs uploaded?
No. The tools read and rewrite them 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.
Can I sign or redact a PDF?
Yes, in the PDF Editor. Its redaction deletes the text underneath instead of only covering it.
Can I get the text out of a scan?
Yes, in English. PDF to Text draws each page that has no text and reads it with OCR in this tab. The OCR model downloads only when a scan turns up.
Do you add a watermark?
No. Nothing is stamped on your document, at any size or count.
