Add Page Numbers to PDF Locally
A printed contract, a court bundle, a training handout — many documents simply read better, and are easier to reference, when the pages are numbered. Adding numbers to a header or footer is a small finishing touch that usually means opening a heavier editor. PDFTasker writes page numbers into the header or footer in the browser and exports a numbered copy, without uploading the original.
Privacy and trust
Header and footer edits stay on device
Numbering is often the last step before a document goes out, exactly when you would rather not route it through a server. PDFTasker draws the numbers into a new PDF locally with pdf-lib, leaving your source file untouched and on your device. Add the numbering, check the result, and send the copy — no upload involved in stamping a footer.

FAQ
Page Numbers PDF FAQ
Can I place numbers in the header or footer?
Yes. You can place page numbers at the top or bottom and choose the alignment that fits the document. Use the preview to keep numbers away from signatures, footnotes, stamps, and form fields. The goal is a readable final copy, not just adding a counter.
Does numbering upload my PDF?
No. The browser writes the page numbers locally after you choose the file. The source PDF is not sent to a numbering server for routine processing. That matters for applications, contracts, packets, and scans where page labels are useful but the document should stay on your device.
Is the original file changed?
No. PDFTasker creates a new numbered copy and leaves the original file as it was. Keep the source until the numbered output is accepted. That way you can adjust placement, size, color, or starting number without damaging the document you started from later if needed.
Can I start numbering from a custom number?
Yes. Use the numbering controls to match the section or packet you are preparing. This helps when the PDF is part of a larger submission and page one is not supposed to mean the first physical page in the file. Always compare the output against the recipient instructions.
When should I skip adding page numbers?
Skip numbering when the recipient requires the original file, when existing page labels already matter legally, or when numbers would cover important content. If the PDF is a scanned form with tight margins, test one export and inspect every page before sending the numbered copy.
Will the numbers cover existing content on the page?
They are drawn at a fixed position on each page, so on documents with tight margins or full-bleed scans the number can land on top of existing content. The fix is cheap: export one copy and flip through it before committing to the numbered version. Pay particular attention to forms, scanned receipts, and anything with footer text — those are the layouts where the corner of the page is already busy. Your original stays untouched, so a second pass costs nothing.
Do the page numbers match labels the PDF already has?
The tool numbers physical pages in order: the first page in the file is 1, the second is 2, and so on. Documents sometimes disagree with their own files — a cover page that should not count, front matter numbered in roman numerals, a brief whose section numbering matters more than page order. The tool does not try to guess those conventions. If your recipient expects \"page one\" to be the first content page, check the sequence on the exported copy before sharing it.
Does adding numbers change anything else in the file?
No. The tool draws a number onto each page and saves the result as a new PDF — existing text, images, and form content are left exactly as they are, and nothing is re-rendered or recompressed in the process. Your original file stays unnumbered on your device, and the numbered version exports separately. If the position or format turns out wrong, adjust the settings and export again from the untouched source; nothing is ever overwritten.
