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.
