A document that leaves your hands page by page needs to say what it is on every page. That is what headers and footers are for, and re-exporting from the original file is not an option when the original is somebody else’s. Bates numbering is the same operation with stricter rules: a prefix and a fixed-width, unbroken sequence, applied so that every page of a legal disclosure carries one identifier that can be cited unambiguously and cannot be confused with a page number.
PDF is the universal document format: it locks layout, fonts and images so a file looks identical on every device and printer. Scans, invoices, forms, e-books and reports all travel as PDF. Because a PDF is a container rather than an image, turning its pages into JPG or PNG pictures — or bundling pictures into a PDF — are among the most common file tasks there are.
Documents rarely stay whole. Pages get printed and separated, photographed one at a time, pulled into an email or filed on their own. The margin is where a document says what it is on every one of them — a title, a date, a matter reference, a confidentiality mark — and it is a place you cannot reach once the file exists, because re-exporting means having the original, which is usually somebody else’s.
Left, centre and right, at the head and the foot. Anything you type goes on every page, and two tokens are filled in as it goes: {page} for the number of the page it lands on and {pages} for the total — so Page {page} of {pages} comes out as it should on all of them.
It looks like page numbering and is not. A page number describes a position and restarts with every document; a Bates number is an identifier for one specific page of one specific disclosure, and it must be unique, unbroken and citable years later. That means three rules: a prefix, a fixed number of digits, and a sequence that continues rather than resets.
The fixed width is the part that quietly matters. If page 998 is stamped ABC-998 and page 1000 is stamped ABC-1000, the numbers no longer sort, no longer align, and no longer look like the same series to anyone reading a citation. Padding to a set width — ABC-000998, ABC-001000 — is what keeps a disclosure referenceable, which is why the digit count is set once and applied to every page.
The stamp sits in the margin, so on a document with generous margins it sits in white space; on one already printed to the edge it may land on content. Look at the first page before running a long document. The text is drawn onto the page and stays selectable, which is what lets a Bates number be copied out of the file rather than retyped.

Yes. Add as many files as you like — each one is processed in sequence with its own progress status, and you can download the results individually or all together as a ZIP archive.
No. Pages are copied at the object level — text, fonts, images and vector content are carried over as-is, without re-rendering. The output keeps the same sharpness and searchable text as the original.
Page numbers restart with each document and describe a position. A Bates number is an identifier: it has a prefix, a fixed number of digits, and it keeps counting, so page 1 of the second file might be ABC-000248. It is what courts and discovery processes reference, which is why it must never restart or change width.
