Header & Footer: how it works
To add a header or footer to a PDF, open the Header & Footer tool, add your file, enter text with optional page numbers and dates, and download. The text is stamped in your browser and the file is never uploaded.
How to use Header & Footer

In your browser vs. uploading to a server
Best for branding or labelling a document set consistently across every page.
Frequently asked questions
How do I add a header or footer to a PDF?
- Open the Header & Footer tool, enter your text (with page numbers or dates if you like), and download; it is applied to every page in your browser.
Are my files uploaded to a server?
- No. PDFER runs entirely in your browser using WebAssembly and JavaScript. Your files are read into memory on your device, processed locally, and never sent to PDFER or any third party. Closing the tab or leaving the tool erases them from memory.
