FAQ

Can I start numbering from something other than 1?
Yes — set any starting number, useful when this document continues from another one.
Does it skip pages that already have a number printed in the content?
No — it adds a new number regardless of existing content; check the result doesn't overlap an existing number in your design.
Does this tool upload my PDF anywhere?
No — numbering happens entirely in your browser.
