Watermark images online
Add styled text or a logo and download a full-resolution copy without uploading it.
How to watermark an image online
Choose one image, add text or a logo, choose one of five standard positions or custom coordinates, then adjust font, weight, size, color, opacity, tiling, and blend mode. The preview is scaled only by CSS; the downloaded image retains the source resolution.
Privacy and limitations
No image is uploaded. The tool handles one image at a time. Animated files export their displayed frame, and canvas output does not retain source EXIF metadata.
