100% client-side PDF tools
Whether you are handling contracts, tax returns, scanned archives, or everyday paperwork, adding page numbers to PDF documents is one of the most common PDF jobs professionals and students run into. Cloud converters promise speed, but they also ask you to upload confidential files to unknown servers — often with daily limits, watermarks, or paid tiers.

BrainyPDF solves this differently. Our Add Page Numbers tool is completely free, requires no account, and processes every byte locally in your browser. Your PDF never leaves your device.
Why use BrainyPDF for adding page numbers to PDF documents?
Traditional online PDF services — including popular names like iLovePDF and Smallpdf — route your documents through their infrastructure. BrainyPDF runs entirely client-side using modern browser APIs. Open the tool, drop your file, download the result. No queue, no upload bar, no subscription upsell.
