Image Watermark
ImageWatermark images online free: upload a base image and a logo, pick the position and opacity, and download the result as PNG. Runs entirely in your browser.
What is an Image Watermark?
An Image Watermark places a logo or image stamp over your photo at the position and opacity you choose, protecting your content or showing ownership on social shares.
How to add a watermark
- Load the base image and the watermark image (a logo or signature).
- Set the position, size and opacity.
- Download the resulting image as PNG.
Tips for a subtle mark
Lower opacity and a corner position keep photos clean while still identifying the source. Export as PNG so the composite keeps a transparent background where needed.
