The overlay image is automatically centered on top of the base image so you can focus on the creative result, not manual alignment.
Adjust overlay opacity and scale with smooth sliders to create subtle watermarks, strong double exposures, or anything in between.
All overlay rendering happens locally in your browser. No uploads, no servers, and no risk of your images being stored elsewhere.
Create clean overlays and blends in three simple steps
Choose your base image first, then select the overlay image. You can drag and drop or click to upload JPG, PNG, or WebP files.
Use the opacity and size sliders to control how strong the overlay appears and how large it should be relative to the base image.
Preview the combined result in real time. When you are happy with the blend, download the merged image as a high-quality PNG file.
