Frequently asked questions
Can the watermark be removed later?
It is drawn into each page, so it cannot be switched off by a viewer. Keep an unwatermarked copy if you need one.
Can I tile the watermark across the page?
Yes. Choose Tiled to repeat the text in a diagonal pattern over the whole page.
Are my files uploaded anywhere?
No. The whole tool runs inside your browser using JavaScript. Your files stay on your device, nothing is sent to a server, and nothing is stored. You can even use it offline once the page has loaded.
Is it really free?
Yes. There is no account, no watermark, no file-size tier and no daily limit. Use it as often as you need.
