About this tool
Add page numbers to PDF draws a number on each page, on this device. You can start at a number other than 1 and skip the first page when that page is a cover. The numbers are painted into the file. They will not fix a table of contents that already has the wrong pages. Check the corners so the number does not sit on a footer you already had.
Add page numbers to PDF stays on this device. The download is the copy you keep, and Weesize does not store a second one. Close the tab when you are finished and the bytes are gone.
- No upload: numbers are drawn into a copy in this browser, not by an online stamp service.
- Speed: the file does not travel to a server and back, so the wait is only the work itself.
- Quality: the original is kept when the new file would be worse or is not actually smaller.
