Add a watermark to photos

Protect your pictures with your name or logo. Place a single watermark or tile it across the image, set the opacity, rotation and margins, and apply the same settings to every photo in the batch. Files are processed on your device.

Questions and answers

Can I use my own logo?

Yes. Add a PNG with a transparent background for the cleanest result.

Will the watermark reduce image quality?

The output is re-encoded at the quality you choose. Use a high setting to keep the photo looking the same.

Is anything uploaded?

No. The watermark is drawn in your browser.
