FAQ
Can I start numbering from something other than 1?
Yes — set "Start at" to any number, useful when this PDF continues from another document.
What does "Page 1 of 12" format use for the total?
The document's actual page count, not affected by your chosen starting number.
Does this work on scanned/image-only PDFs?
Yes — page numbers are added as a new text layer on top of each page, regardless of what the existing page contains.
Is my PDF uploaded anywhere?
No — numbering happens entirely in your browser using pdf-lib.

Adding numbers page by page in an image editor is slow. PDF Page Numberer stamps the whole document in one click.
