Add Bates Numbers to a PDF (Free)
Bates numbering stamps a unique, sequential identifier on every page of a document so it can be referenced precisely during production, discovery, or filing. Paralegals and attorneys have long paid for desktop legal software or premium PDF suites just to do this. PdfXpo does it free, in your browser: set a prefix, a start number, and digit padding, and it labels every page in one pass — hundreds or thousands of pages, perfectly sequential.
Because legal sets are confidential, the file should never be uploaded to a stranger's server. PdfXpo runs entirely on your device via WebAssembly, so the document never leaves your control. It is free and unlimited, with no account and no watermark — a genuine replacement for paid Bates tools, without the cost or the privacy risk.
