Add Watermark to Images

Add a watermark to photos, text or logo, many at once

Mark your photos with text or a logo. Choose position, size and opacity, and apply the same settings to many photos at once.

Text and logo

For a text watermark, set the wording and color, and turn on a shadow so it stays visible on light backgrounds. For a logo, choose an image file; a PNG with a transparent background places only the logo shape. Size is a percentage of the photo width, so photos of different resolutions get a similar look.

Position and repeat

Place it in one of nine spots from top left to bottom right, or repeat it diagonally across the whole photo. A repeated watermark survives cropping off a corner, which makes it more effective against reuse. The preview shows the first photo, and the same settings apply to all of them.

Saving

Save as JPG, PNG or WebP, up to 50 photos at a time. With two or more results you can download a ZIP, and each saved name is the original followed by -watermarked. The watermark is merged into the picture and cannot be removed later, so keep your originals.

Frequently asked questions

Are my photos uploaded?

No. The photos and logo are processed only inside this browser and are not sent anywhere.

Does it fully prevent reuse?

No. A watermark makes reuse harder but cannot stop it completely. Repeating it across the photo at a moderate opacity works better.
