Add Page Numbers to a PDF on iPhone
The Files app on an iPhone can mark up a PDF, but it has no way to stamp a running page number on every page, and the App Store is full of PDF apps that want an account and a subscription before they will do it. FixTools works differently. Open the tool in Safari, upload the PDF from your phone, and choose where the numbers sit 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 entirely in the browser, the PDF is opened and numbered on the phone itself. Nothing is uploaded to a server, there is no account to create, and no watermark is stamped on the result. It works the same in Safari and Chrome on iOS, and the finished file lands straight in your Files or Downloads, ready to email or share.

Why numbering in the browser beats a PDF app on iPhone
Most mobile PDF apps upload your document to their servers to process it, which means a report, contract, or personal file passes through a company you have never heard of just so a number can be drawn on each page. That is a lot of trust to hand over for a task the phone can do on its own.
FixTools does the numbering with JavaScript that runs inside Safari. The file is read into the browser, the numbers are drawn onto each page, and the new PDF is handed back to you, all without a single network request carrying your document. If you turn on airplane mode after the page loads, the numbering still works, which is the simplest proof that nothing is being sent anywhere.
How to use this tool
Open the Add Page Numbers tool in Safari, tap to upload your PDF, and choose a bottom position and format. Tap Add Page Numbers, then download the numbered PDF to your iPhone.

Pro tips
Get better results with these expert suggestions:
Save the PDF to Files first
If the document arrived as an email attachment, save it to Files so it is easy to pick in the upload step.
Pick "Page 1 of N" for printouts
If the pages will be printed and handed out, the "Page 1 of N" format helps readers keep them in order.
Keep the original
Hold on to the unnumbered PDF in Files in case you want to renumber with a different position.
Share straight from Files
After downloading, use the Files share sheet to email or AirDrop the numbered PDF without opening another app.
