Drop a PDF and I'll number the pages.
Add Page Numbers
Add page numbers to a PDF. Pick the corner, the starting number, and whether to number the whole document or a range.
Good to know
- Numbering counts across the pages you stamp, so a range starting at 3 runs 3, 4, 5.
- Sideways pages are handled — the number lands where the reader sees the corner.
- The preview shows the first numbered page before you download anything.
Your files stay on your machine
This tool runs entirely inside your browser tab. Nothing is uploaded, stored, or sent to a server — close the tab and every trace is gone.
These are the free ones — see the full suiteHow big a file can it take?
There is no upload, so there is no upload limit — but the work happens in this tab, which means your browser’s memory is the budget. Nothing here will refuse a file for being large; a big enough one simply gets slow and, eventually, reloads the tab. The figures below are rules of thumb on a desktop browser, not enforced caps. On a phone or tablet, expect a good deal less.
- Pages are thumbnailed so you can see where the number lands, so page count binds — comfortable to around 500 pages, sluggish past 1,500.
- The stamping itself is cheap; it is drawing the previews that takes the time on a long document.
Password-protected PDFs are declined whatever their size — unlock the file first. If a run does die on a long document, splitting it into volumes and working through them one at a time is the reliable way round it.
