Can I use a logo as a watermark?

Yes. Choose a PNG or JPG file under "Image watermark". You set the width, opacity and position yourself. PNG files with a transparent background work particularly well.

No. The watermark is added entirely in your browser. The PDF and the image never leave your device.

Can I put the watermark on certain pages only?

Yes. Choose "Specific pages" and enter ranges such as 1-3, 5.

Does text in other languages work?

Yes. Text in Latin script is added as searchable text, other scripts such as Chinese or Arabic as an image.

Can the watermark be removed again?

The watermark becomes part of the page and cannot be removed with this tool, so keep your original file.
