Frequently asked questions
Are my files uploaded to a server?
No. This tool runs entirely in your web browser. Your files never leave your device, which makes it safe for private documents.
Can I watermark only some pages?
Yes. Type page numbers or ranges such as 1-3, 7.
Can the watermark be removed?
It is drawn onto the pages, so it cannot simply be deleted in a normal PDF reader, but determined people with PDF editors can still remove it.
