How do I add a watermark to an image?

Upload your image into the tool, select either Text Watermark or Logo Watermark mode, customize the appearance settings (opacity, size, position, rotation), preview the result, then download. Everything is processed locally in your browser with no uploads required.

Can I add a semi-transparent or subtle watermark?

Yes. Use the Opacity slider to adjust how visible the watermark appears. Lower values create subtle attribution while higher values make the watermark more prominent. This is perfect for creating professional-looking watermarks that don't distract from the image.

Can I repeat the watermark across the whole image (tile mode)?

Yes. Select the Tiled/Repeat position mode and the watermark will be placed across the entire image at regular intervals. This is ideal for protecting gallery photos, preventing unauthorized use on social media, and creating branded templates.

Which output formats support transparency for logo watermarks?

Use PNG or WebP output when your watermark logo has transparency or when the underlying image needs to stay transparent. JPG does not support transparency and will fill transparent areas with white. For best results with logo watermarks, export as PNG.

Is the image watermark tool free and private?

Yes. The Image Watermark tool is 100 percent free, runs entirely in your browser using the Canvas API, never uploads your images to any server, requires no account or sign-up, and adds no watermarks beyond what you choose yourself.
