Stamp. Bates numbering and exhibit stamps for discovery, without Acrobat.

Stamp prepares discovery productions in your browser: sequential Bates numbers with your prefix and padding, classic bordered exhibit stamps, protective-order designation legends, CONFIDENTIAL watermarks, page extraction, and splitting at court e-filing size caps. Pro stamps a whole production at once with continuous numbering carried file to file, and writes the production log CSV you would otherwise build by hand. Rotated scans stamp correctly, and encrypted PDFs are refused rather than silently modified.

How to use Stamp

Drop a PDF (or a whole production of them) onto Stamp.

Set your prefix, start number, and position. The live preview shows exactly where the stamp lands.

For batches, order the files; numbering carries continuously from one file to the next.

Run, then download stamped PDFs plus the production log CSV, or grab everything as one zip.

Private by architecture. Stamp processes everything locally in your browser. No uploads, no account, no telemetry. The only network request it can make is Gumroad license verification, and only when you enter a Pro key. Privacy policy.
