Image Watermark

A free browser-based image tool that add text watermark to images with position and opacity control. Process your photos and graphics directly in your browser without uploading to any server. Protecting images with a text or logo overlay is a task professional photographers usually do in batch inside a desktop editor. This watermark tool stamps your images right in the browser, letting you position, scale, and style the overlay with live feedback. Position the text watermark anywhere on the image using nine placement presets or custom x/y coordinates, then adjust font size, color, opacity, and rotation angle. The watermark renders crisply at the source image's full resolution. Type your watermark text or upload a transparent PNG logo, then use the position grid and sliders to set placement, size, opacity, and rotation. The overlay renders on a live preview, and batch mode applies the same watermark to every image you load. Watermark compositing is performed through canvas blending operations in your browser. Because the original photos and stamped copies are processed locally, your unwatermarked files are never exposed to a server.
