Frequently Asked Questions
Is my document uploaded?
No. Bates stamping runs entirely in your browser with pdf-lib — the file never leaves your device.
Can I set a prefix like ABC000001?
Yes. Set a prefix and the number of digits, and each page is stamped like ABC000001, ABC000002, and so on.
Where is the number placed?
You choose the corner. The default is bottom-right, the usual position for Bates stamps.
