Frequently asked questions

How do I confidential watermark?+

Enter your text, drop the photos, and choose where it sits. Set the size and opacity, then download the watermarked PNG.

Can I watermark many photos at once?+

Yes. Drop multiple images and the same watermark is applied to all of them; download them together as a ZIP.

Will the watermark be removable?+

A semi-transparent tiled watermark over important areas is much harder to remove than a small corner mark. For strong protection, increase opacity and coverage.

Are my photos uploaded?+

No. Watermarking happens entirely in your browser; your images and logo never leave your device.
