Bates Numbering
Apply one continuous, padded identifier sequence across a batch of PDFs. Files stay in your browser.
Stamp a continuous, zero-padded Bates identifier sequence (like ABC000001, ABC000002...) across every page of a batch of PDFs, the numbering convention required for legal document production and litigation review. Set a prefix, starting number, and digit padding, then upload your files in the order they should be numbered - the sequence continues seamlessly from one document into the next. Everything runs locally with pdf-lib.
Runs on your device. This tool processes your file inside this browser tab. Nothing is uploaded, so it also works offline once the page has loaded, and closing the tab discards the file from memory.

Common questions
How are multiple documents numbered?
Files are processed in the order shown, and numbering continues across document boundaries.
What happens with multiple files?
The numbered PDFs are returned together in a ZIP.
Can I customize the prefix and digit padding?
Yes - set any prefix text and choose how many digits the number is padded to, matching your firm or organization's convention.
Are my documents uploaded anywhere?
No - numbering is applied entirely in your browser using pdf-lib.
