Konvizi’s “Add page numbers” tool is free, with no sign-up, no watermark and no file limit. All the processing happens in your browser, on your device: your files are never uploaded to a server, which makes it suitable for personal and confidential documents.
Drag your PDF files into the area above or click “Choose files”. You can add several at once.
Bottom center, a corner, the top… and “1”, “1 / 12” or “Page 1 of 12”. Click “Add numbers”.
The numbers are written on every page, on your device.
A thesis, an application file or a contract put together from several files often has no page numbers. Yet they are essential to find your way around, refer to an appendix or check that nothing is missing when printing. Konvizi writes the number on each page without touching the rest of the document.
PDF is the universal document format: it looks the same on every device, keeps its layout and prints without surprises.
Contracts, payslips, bank statements, tax returns: PDFs often hold sensitive information. With Konvizi they never leave your device, are stored nowhere and read by nobody. Most PDF tools copy pages without recompressing them: selectable text, links and quality are preserved.
Your files never leave your device. No upload, no storage.
No upload and no queue: the conversion starts right away.
As many files as you like, with no imposed size limit.
No sign-up, no watermark, no subscription.

Yes, completely. No sign-up, no watermark, no limit on the number of files.
No. Everything happens in your browser, on your device. Your files are never sent over the internet: nobody but you can see them.
They are written in dark grey with the Noto Sans font, at a size suited to the page (about 11 points on an A4 or Letter sheet). Landscape and rotated pages are handled.
Not directly: all pages are numbered starting from 1. You can split off the cover page and the rest with “Extract PDF pages”, number the rest, then put them back together with “Merge PDF”.
Open your browser’s developer tools (F12 key), go to the “Network” tab and run a conversion: no request carries your file. The site also enforces a security rule (Content-Security-Policy) that forbids the browser from contacting any site other than konvizi.com, and konvizi.com is a static site with no service able to receive files.
Yes. Konvizi works in the browser of your phone or tablet (Safari, Chrome…) just like on a computer, with no app to install. Very large files are processed faster on a computer, which has more memory.
