Add Bates Numbers to a PDF

Bates numbering is a legal and business convention of stamping every page of a document with a unique, sequential identifier, such as ABC-000123. It combines an optional prefix, a zero-padded running number, and an optional suffix so pages can be referenced precisely during discovery and review.

No. The stamping runs entirely in your browser with pdf-lib. The PDF never leaves your device, so confidential and privileged documents stay private.

Yes. Choose any prefix and suffix, the number the first page starts from, and how many digits the number is zero-padded to. The number then counts up by one on each following page, continuous across the whole document.

You can place it in the bottom or top, aligned left, center, or right. That is six positions in total. The bottom-right corner is the most common choice for legal productions.

No. The original text, images, and layout are untouched. The tool only draws a small identifier in the margin of each page using a built-in font.
