FAQ

Are my PDFs uploaded?

No. PDFPocket edits PDFs with the open-source pdf-lib and PDF.js libraries running inside your browser. Files never leave your device — ideal for contracts, bank statements and IDs.

Is there a file size or page limit?

No fixed limit. Very large files (hundreds of MB) depend on your device’s memory, but typical documents process in a second or two.

Does it work with password-protected PDFs?

Files that only restrict editing usually work. Files that need a password to open must be unlocked first.
