Bates numbering โ sometimes called Bates stamping or Bates labeling โ is the practice of applying a unique, sequential number-plus-page label to every page of a document set at the start of litigation or production. The number is used as a universal identifier: attorneys, opposing counsel, courts, and e-discovery platforms can all reference the same exact page of the confidentiality-bound record. Options like PLAINTIFF-000001 or DEF-CONFIDENTIAL-000042 bake those identifiers into the page for the lifetime of the file.
This tool is a free Bates numbering PDF online solution that works completely in the browser. Instead of sending your production set to a vendor server, pdf-lib WebAssembly stamps the number coordinates in a fully client-side, zero-upload pipeline โ meaning confidential legal discovery never leaves your machine. No account, no paywall, no watermark.
Why privacy matters for Bates stamping legal PDF online
Law firms hold some of the most sensitive data on earth โ trade secrets, medical records, personnel files, and opposing-counsel correspondence. A "free Bates stamp no upload" promise is only credible if the architecture makes transmission impossible. Here the PDF is decoded, stamped, and re-encoded in the WebAssembly runtime of your own browser tab. You keep the original arbitrary back-boxes, and the output never does a single HTTP request.
Confidential-label compliance for e-discovery
When a protective order requires that confidential material be marked before production, the stamp's job is to make the restriction inviolable on paper. This free Bates numbering software applies real vector text (native, not rasterized), so the label stays crisp at any zoom level in review platforms and your sequential numbers can subsequently be referenced in privilege logs and privilege reports.
