Add an Invisible Digital Watermark to Any Image — Free, Online, No Sign-Up
Most watermark tools slap a visible logo across your photo. That works as a deterrent, but it ruins the image. What if you could protect your photos from theft and prove image ownership without anyone knowing the watermark is there?
Our free invisible watermark tool embeds a hidden watermark — your name, copyright notice, or any custom text — directly into the image. The watermarked photo looks identical to the original, but your ownership information is woven into every part of it. Unlike simple pixel-level methods, our watermark survives JPEG compression and format conversion.
Come back anytime with the watermarked image and use the Verify tab to extract the hidden text and prove it's yours. No account needed, no original image required, no software to install. This is a free Digimarc alternative that runs entirely in your browser — your photos are never uploaded anywhere.
