Watermark Image
Upload an image, choose a text or image watermark, adjust position, opacity, and rotation, and download the result.
How it works
All processing happens locally, in your browser. Your images are never sent to any server, which keeps things more private and secure. The text watermark lets you choose the font, size, and color. The image watermark uses a second file (for example, a logo) as a stamp. In both cases, you control the position (on a 3x3 grid), opacity, and rotation, with the preview updating in real time.
