Quick answer: To add page numbers to a PDF on your iPhone for free, open Safari, go to rapidtools.online/add-page-numbers-pdf, pick your PDF, set the start number and position, and tap Add Page Numbers — then download. No app, no account, and the file never leaves your phone.

The iPhone is great at viewing and signing PDFs, but it has a real gap: neither the Files app nor Markup can add sequential page numbers to a document. You do not need to email the file to a computer or install a paid app, though — a browser tool handles it on the phone.

Add Page Numbers in Safari (No App)

This works on any iPhone in Safari (or Chrome), with no install, no account, and no file upload:

  1. Open Safari and go to rapidtools.online/add-page-numbers-pdf.
  2. Tap the upload area and choose your PDF from Files, iCloud Drive, or wherever it is saved.
  3. Set the starting number (begin at 1, or continue from another number for a supplemental set).
  4. Choose the position — bottom center, bottom right, or bottom left — and add a prefix like "Page " if you want.
  5. Tap Add Page Numbers. Processing happens right in Safari.
  6. Tap Download to save the numbered PDF back to Files.
Skip the cover page: If your document has a title page, start numbering from page 2 (or set the starting number to account for it) so the count matches the printed pages.

Why the Files App Cannot Do It

iOS 16 and later added handy PDF actions in the Files app — you can rotate, sign, and mark up — but there is no option to insert real page numbers that increment across every page. Markup only lets you place static text by hand, one page at a time, which is not practical for anything longer than a couple of pages. A browser tool applies numbers to the whole document in one step.

What You Can Customize

  • Prefix: add text before the number, such as "Page ", a matter number, or a Bates-style code.
  • Start number: begin anywhere — useful for reports split across files.
  • Position: bottom center is standard; bottom right is common for legal documents.

For legal discovery specifically, you may want sequential Bates numbering instead — see Bates Stamp PDF.

Frequently Asked Questions

How do I add page numbers to a PDF on iPhone for free?

Open Safari and go to rapidtools.online/add-page-numbers-pdf. Pick your PDF from Files or iCloud, set the starting number, position, and any prefix, then tap Add Page Numbers and download. No app is needed, and the file never leaves your phone.

Can the iPhone Files app add page numbers to a PDF?

No. The Files app and Markup can sign and annotate PDFs but cannot insert real, sequential page numbers across every page. For that you need a browser tool or a dedicated app — the browser tool is faster and requires no install.

Can I start numbering from a specific page or number?

Yes. The tool lets you set the starting number (for example, begin at 1 or continue from 247 for a supplemental set) and choose which pages get numbered, so cover pages can be skipped.

Where do the page numbers appear?

You choose the position — bottom center, bottom right, or bottom left are the usual choices. You can also add a prefix such as "Page " or a document code before the number.

Is it safe to number a PDF online on my iPhone?

With RapidTools, yes — the PDF is processed entirely in Safari on your device and is never uploaded to a server. That matters for contracts, legal filings, or any document you would not want on a third-party server.
