You can add page numbers to a PDF here in your browser: pick the position and format — plain numbers, "1 of N", or "Page 1" — and download the numbered file. It all runs on your device, free, with no sign-up and no watermark.

Limits & good to know
Six positions are available — any corner, top-centre, or bottom-centre — in three number formats.
Numbers are added as new text over the page; existing content is untouched.
Numbering runs one-to-N across the whole document; custom start numbers and per-section numbering are not supported yet.
A password-protected PDF must be unlocked first.
Frequently asked questions
Are my files uploaded to a server?
No. TrulyFreePDF runs entirely in your browser — your file is opened and processed on your own device and is never uploaded, stored, or shared.
Which formats are available?
Plain numbers (1, 2, 3), "1 of N", and "Page 1", in six positions: any corner, top center, or bottom center.
Is this really free, or free "until you hit a limit"?
Really free. Unlike most "free" PDF sites there is no task-per-day cap, no locked Pro features, no watermark stamped on your file, and no payment step before download. Every tool is the full tool.
