How to watermark images

Choose the images to watermark.
Type your text (for example © Your Name) or choose your logo, then pick a position, size and opacity.
Press Watermark and download the images, one by one or as a ZIP.

Options

Text or logo: a PNG, WebP or SVG logo with a transparent background looks best.
Nine positions, from the corners to the center, with a small margin from the edge.
Repeat across the image as a diagonal pattern, which is harder to crop out.
The text size follows the image size, so the watermark looks the same on small and large photos.
An optional soft shadow keeps white text readable on light areas.

The watermark becomes part of the picture. Keep your originals: it can't be removed again.
Animated GIFs and WebPs keep only their first frame.
Save as PNG or a high quality setting to avoid extra compression.

Everything happens in your browser. Your images are never uploaded, so private photos and client work stay with you.

Yes. Add as many images as you like; the same watermark is placed on each one, scaled to its size.

Not from the new file: it is drawn into the pixels. Your original files are not changed.

A PNG or SVG with a transparent background, so only the logo itself appears on the photo.

No. They are processed in your browser and never sent anywhere.
