Questions

Can people remove the watermark?

It is drawn into the page, so it can't be clicked away. Someone with a full PDF editor could still take it out.

Can I use my logo?

Yes. Pick Image and choose a PNG or JPG. A PNG with a see-through background looks best.

Can I do several files at once?

Yes. Choose or drop several files. Each one gets the same settings, and you save them all in one ZIP.

What does behind the page do?

The page is drawn over the watermark, so lines and text stay on top. Scanned pages and filled shapes will hide it, so use it on drawings made of lines.

Are my files uploaded?

No. The tool runs in your browser, so your files never leave your device. Nothing is sent to us or kept after you close the tab.

Is it free?

Yes. There is no sign-up, no watermark on your file and no daily limit.

Does it work offline?

Yes. Once the page has loaded you can turn off Wi-Fi and the tool still works.
