Need to add page numbers to a PDF on your Android phone? Skip the app store — a browser tool handles it completely. Here is how.
Open Chrome and navigate to pdfeditor.onl/page-numbers. The tool loads on any Android phone or tablet.
Tap the upload area. Android's file picker opens — navigate to Downloads, Google Drive, or wherever the PDF is saved.
Tip: PDFs from WhatsApp are stored in the WhatsApp/Media/WhatsApp Documents folder. Browse to it via the file picker to upload.
Choose the corner or center position for page numbers. Set the font size and select whether the first page (cover) should be numbered. Standard professional documents use bottom center at 10pt.
Tap Download PDF. Chrome saves it to your Android Downloads folder. Open the PDF to confirm page numbers appear on every page.
If existing page numbers are embedded in the page content (not in a header/footer layer), they cannot be removed without editing the page image. For scanned PDFs with printed page numbers, you may need to cover them with white boxes using the Add Image tool before adding new numbers.
No watermarks are added. The page numbers are clean vector text — no branding, no watermark.
