Adding page numbers to a PDF on iPhone is easy with a browser-based tool — no app download required. Here is how to do it in Safari in under two minutes.
Navigate to pdfeditor.onl/page-numbers. The tool is fully responsive and works on iPhone screens.
Tap the upload area. Select the PDF from your Files app, iCloud Drive, or any accessible location. The file is processed locally on your device.
Tip: If the PDF is in your email, save it to Files first: tap the attachment, then tap Share → Save to Files.
Choose the position (bottom center is most common), font size (10pt for standard documents), and the starting page number. Toggle whether to show the number on the first page.
Tap Download PDF. Safari saves the numbered PDF to your iPhone Downloads folder in the Files app. Open it to verify the page numbers appear correctly.
Yes. The page number tool supports "Page X of N" format — toggle this in the settings before downloading.
Yes. The same steps apply on iPad — the tool is optimized for all iOS screen sizes.
