Frequently asked questions

Is my PDF uploaded to a server?
No. All watermarking happens inside your browser using pdf-lib. Your file is never sent anywhere.
Can I add an image watermark?
This tool supports text watermarks only. Image watermarks are coming soon.
Will the watermark appear on every page?
Yes, the watermark is applied to every page of your PDF.
Can I remove a watermark later?
No, the watermark becomes part of the PDF. Keep an original copy if you need one.
