Add a text or image watermark to any image. Position it anywhere, control opacity, scale, and rotation. Output as JPG, PNG, or WebP. Runs locally — your photos and your watermark do not leave the page.
A watermark is not a deterrent against determined image theft — anyone who wants to remove a watermark from a published image can do so with five minutes and a content- aware fill tool. Modern AI inpainting makes this trivial.
Watermarks do serve a few real purposes:
Subtle watermarkssit at low opacity in a corner — typically 20-40%. They are easy to crop out, but they preserve the image's visual impact and signal attribution to attentive viewers.
Prominent watermarks overlay the center of the image at higher opacity (60-80%). They are hard to remove without obvious damage, but they also degrade the image significantly. Used by stock photo sites for preview images, since the goal is to prevent free use.
Repeated tile watermarks place the same small mark across the image in a grid. Maximum protection against cropping, maximum visual cost. Used for documents with embedded confidentiality markings.
Bottom-right corner is the de facto standard for photo attribution — viewers know to look there. Bottom-left is less common but works equally well. Center placement prevents cropping but interferes with the image content. Edges are easiest to crop out; centers are hardest.
If protection is the goal
The watermark composite happens on a canvas in your tab. Your image and your watermark file are both processed locally and the output is downloaded directly. Nothing is uploaded.
