Add header and footer to a PDF
The tool opens your PDF in the browser with pdf-lib and draws header/footer text (and optional page numbers) on each page. The file is not uploaded to FlashKit.
This is for letterheads, invoice numbers, and “Page X of Y” — not a full design editor. Encrypted or heavily compressed PDFs can fail. Keep a copy of the original.
How to Use
- Select a PDF from your device. Encrypted files may not open.
- Enter header and/or footer text. Enable page numbers if you need them.
- Preview the first page if the UI offers it, then apply the stamp.
- Download the new PDF. Compare page count with the original before you send it.
Key Features
- Client-side pdf-lib processing
- Headers, footers, and page numbers
- No FlashKit file storage
- Works without installing a desktop PDF suite
Frequently Asked Questions
Does this flatten forms or signatures?
Stamping can affect interactive forms or some signed files. Test a copy. For legal signatures, use a dedicated signing workflow.
Is the PDF uploaded?
No. Bytes stay in the tab. Very large files can exhaust mobile memory.
Can I add a logo image in the header?
The current tool is text-oriented. For a logo-heavy letterhead, compose the PDF in a layout tool, then use this page for page numbers only.
