Why Use This Image Overlay Tool?
Blend images for watermarks, double exposure, and creative compositions in your browser
Perfectly Centered Overlays
The overlay image is automatically centered on top of the base image so you can focus on the creative result, not manual alignment.
Fine-Grained Control
Adjust overlay opacity and scale with smooth sliders to create subtle watermarks, strong double exposures, or anything in between.
Private, Browser-Based Processing
All overlay rendering happens locally in your browser. No uploads, no servers, and no risk of your images being stored elsewhere.
How to Overlay One Image on Another

Adjust Overlay Settings
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 and Download
Preview the combined result in real time. When you are happy with the blend, download the merged image as a high-quality PNG file.
Frequently Asked Questions
Common questions about overlaying and blending images
What can I use image overlay for?
You can use image overlay to add watermarks, create double exposure effects, combine logos with photos, or build creative social media graphics in a few clicks.
Will my images be uploaded to a server?
No. All processing happens directly in your browser using the canvas API. Your images are never sent to any server, which keeps your files private.
What file formats are supported?
You can upload JPG, PNG, and WebP images for both the base and overlay. The final merged image is exported as a PNG file.
Can I control where the overlay appears?
This tool automatically centers the overlay on top of the base image for a clean result. For most watermark and blend use cases, centered placement works best.
Will the overlay reduce my image quality?
No. The merged result is rendered at the original base image resolution. As long as you upload high-quality source images, your output will remain sharp.
