Bates Numbering

A fixed-length identifier stamped on every page of a document production - a prefix plus a zero-padded number such as ABC000123 - so any page can be cited unambiguously. It is standard in legal discovery.

Yes. Add the files in order and the sequence runs on from one to the next; the first and last identifier of the whole set are shown before you save, ready for the production log.

Nothing is uploaded: the file is opened and processed inside your browser and never leaves your device. Close the tab and it is gone. That matters when the documents are privileged.

Prefix and suffix are free text, the digit count is adjustable (six is the convention), and the stamp can sit at any of nine positions in the font, size and colour you choose.

Yes - set the start number to the next identifier and the sequence carries on. Saving the prefix, digit count and position as a template means the next batch is one click away and comes out looking identical.

Yes. It is written as real text, not a picture, so a reader finds it with a search and anyone can copy it out of the page - which is the point of an identifier meant to be cited.

Yes. Drop in a .docx, .xlsx or .pptx file or an image (JPG, PNG, WebP...) and it is turned into a PDF in your browser as it arrives - an image onto an A4 page - then handled like any other PDF; nothing is uploaded. The conversion is our own, so the result can differ slightly from Office's own PDF export: a font may be substituted and charts are left out. The file list shows a warning when something couldn't be carried over.
