Numbering the pages of a PDF on an Android phone usually means installing another app that wants storage permissions and an account before it will do anything. FixTools skips all of that. You open the tool in Chrome, upload the PDF from your phone, and choose where the numbers go and which format you want. Tap Add Page Numbers and the numbered file is ready to save back to your device. Because the tool runs in the browser, the PDF is opened and numbered on the phone itself, with nothing uploaded, no permissions requested beyond picking a file, and no watermark added. It works across Android phones and tablets in any modern browser, and the finished file lands in your Downloads ready to email or share. For the common case of numbering a report or a set of notes, it replaces a whole app with a single web page.

Android PDF apps tend to ask for broad storage access and often route your document through their own servers to process it, which is a lot of permission and trust for adding a number to each page. Many also bundle ads or push a subscription the moment you try to export.
FixTools runs in Chrome and numbers the PDF on the phone itself. It only ever touches the one file you choose, nothing is uploaded, and there is no app sitting in the background afterwards. Enable airplane mode after the page loads and the numbering still works, which shows the document is never leaving the device.
Open the Add Page Numbers tool in Chrome, upload your PDF, and choose a bottom position and format. Tap Add Page Numbers and download the numbered file to your phone.

Use "Page 1 of N" for printed sets
When the pages will be printed, the "Page 1 of N" format helps keep the stack in order.
