Add Watermark to Image Online — Free Tool

Watermarking images is essential for photographers, content creators, and businesses who share images online. A watermark deters unauthorized use and ensures your brand is visible even if the image is shared without attribution. Our free watermark tool lets you add customizable text overlays to any image directly in your browser.

Choose your watermark text, position (corners or center), opacity, and font size. The watermark is applied using the Canvas API and baked into the exported JPEG — no server processing, no uploads, completely private.
