PDF Agile
For deeper PDF editing beyond what a free browser tool can do, PDF Agile's editor handles text reflow and redaction in one place.
Our tool preserves layout on merge or split but doesn't offer in-place text editing — PDF Agile does.

No. Page numbers are added entirely in your browser using pdf-lib. Your file never leaves your device — you can disconnect from the internet after the page loads and the tool will still work.
Multiple formats: plain digits (1, 2, 3...), padded digits (01, 02...), dash-wrapped (-1-, -2-...), prefixed (Page 1, Page 2...), and fractional (1/10, 2/10...). You can also use a custom prefix or suffix.
A 9-position grid covers every corner and edge: top-left, top-center, top-right, middle-left, middle-center, middle-right, bottom-left, bottom-center, bottom-right. You can also adjust the margin offset.
Yes. Set any starting number — useful when the PDF is part of a larger document. If you select a starting page, only pages from that point onward are numbered.
No. Only the page numbers you configure are added. No watermarks, no logos, no hidden text — the output is a clean PDF with your chosen numbering.
You'll be prompted for the password. Decryption happens locally in your browser and the password is never sent to any server. After unlocking, page numbers are applied normally.
Currently the tool uses the default PDF font (Helvetica) at a readable size. For custom fonts or styling, export the PDF and use a desktop editor for fine-grained control.
Yes. No charge, no sign-up, no watermark, no limit on file size or number of conversions. The tool is supported by non-intrusive advertising on the surrounding pages.
