How it works
Add your PDFs
Drop one or many PDFs — they stamp in the order shown (use the arrows to reorder). Nothing is uploaded.
Set the stamp
Pick a prefix, starting number and zero-padding — the preview shows exactly what page one gets.
Download one file
Hit Stamp Bates numbers. Everything merges into a single PDF with continuous sequential stamps.
Tips
- Order matters. Use the ↑ ↓ buttons to set the file sequence before stamping — numbering follows it.
- Padding keeps sorting sane. ABC000001 sorts correctly where ABC1, ABC10, ABC2 do not.
- Bottom right is the convention. Most courts and firms expect the stamp there — it is the default.
- One merged file. Multi-file productions come out as a single PDF — exactly what e-discovery wants.
Frequently asked questions
How does numbering work across multiple PDFs?
Files are merged in the order shown and numbered continuously — if file one has 10 pages starting at ABC000001, file two starts at ABC000011.
What is zero-padding in Bates numbering?
It left-pads the number with zeros to a fixed width — e.g. 6 digits turns 1 into 000001, so stamps sort correctly as text.
Can I stamp just one PDF?
Yes — a single file works fine. The merge step simply has nothing to combine.
Are my documents uploaded anywhere?
Never. Stamping runs 100% in your browser — important for legal files.
How does Bates numbering work across multiple PDFs?
You load the PDFs in production order, and the tool stamps them as one continuous sequence — if file one ends at ACME000340, file two starts at ACME000341 — then merges everything into a single numbered PDF. The file order you set defines the sequence, so arrange exhibits and records correctly before stamping. Never let numbering restart per file; duplicates defeat the purpose.
What is zero-padding in Bates numbering, and how many digits should I use?
Zero-padding writes numbers with leading zeros (000123 instead of 123) so they sort correctly as text in databases and spreadsheets. Six digits is the standard convention — it handles productions up to 999,999 pages and keeps every number the same width on the page, which looks professional and sorts reliably.
Can I Bates-stamp just one PDF?
Yes. A single PDF is simply a one-file production — set your prefix, starting number, and padding, and every page gets stamped in sequence. This is common for standalone exhibits or when adding to an existing production where you know the next number from your log.
Should I redact or Bates-stamp first?
Redact first, then stamp. The numbering must reflect the final production set — redacting after stamping can change page counts and leave positioning artifacts. The correct pipeline is: finalize the pages, redact sensitive content, then Bates-stamp the redacted set as the last step before production.
Can I use Bates numbers if a production was already numbered by someone else?
Yes, as long as you continue the sequence rather than restarting it. Check the last number used in the existing production (your production log should record it) and set that +1 as your starting number, keeping the same prefix and padding. Overlapping ranges create duplicate numbers, which undermine citation reliability.
Are my legal documents uploaded when I Bates-stamp online?
Not with EzySize — the stamping runs entirely in your browser, so case materials never leave your machine. This matters more for Bates work than almost any other PDF task, since productions routinely contain privileged or confidential content. Verify any tool's privacy claims before trusting it with litigation documents.
