Add Watermarks & Page Numbers Online (100% Private)

Add custom text watermarks or footer page numbers to your documents directly inside your browser.

In-Browser PDF Annotation and Watermarking

Adding security stamps, copyright warnings, or page numbering traditionally meant sending your documents to cloud conversion APIs.

Using web-standard vector manipulation directly inside client memory, your document pages are updated instantly without transmitting any byte to an external server.

Frequently Asked Questions

Can I remove the watermark later?

Watermarks added through this tool are baked into the PDF render layer. To remove them, you would need to revert to the original unmodified PDF.
