Apply sequential Bates numbers across one PDF or a whole batch — useful for legal productions and document sets — without uploading files. PDFPeach stamps pages in your browser with style presets or a custom pattern using placeholders like [BATES_NUMBER] and [FILE_NUMBER].
Choose stamp location, where the sequence continues from, and optionally expand margins so the stamp does not cover existing text. Multiple files download as a ZIP. Free and private.
How to add Bates numbering
- Drop one or more PDFs into the uploader (order matters for multi-file sequences).
- Choose style or custom pattern, position, sequence start, and margin options.
- Download the stamped PDF, or a ZIP when you processed multiple files.

[BATES_NUMBER]— the running Bates value for that page in the sequence.[FILE_NUMBER]— identifies which file in a multi-file batch the page belongs to.
Multi-file batches
Add several PDFs in the order you want the sequence to follow. Numbering continues across every page of every file. Outputs for multiple inputs are packed into a ZIP.
Margins and placement
Pick header/footer-style positions (left, center, right). Increase margins adds a blank border around each page and places the Bates stamp in that margin so it is less likely to overlap existing content.

What do [BATES_NUMBER] and [FILE_NUMBER] do?
[BATES_NUMBER] inserts the running Bates value. [FILE_NUMBER] inserts the index of the file in a multi-file batch so stamps can show both sequence and source file.
What does Increase margins do?
It adds a blank border around each page and places the Bates stamp in that margin so it is less likely to overlap existing content.
Are my files uploaded?
