Analyzing images...
Overall Similarity Score
Select your original or "before" image (JPG, PNG, GIF, WebP) in the first upload box.
Select the modified or "after" image you want to compare in the second upload box.
Click "Compare Images" to view the similarity score, visual diff map, and metadata comparisons.
The pixel difference map takes your two images and highlights the exact pixels that have changed. It will display a visual canvas where identical pixels are hidden or faded, and changed pixels are highlighted in red to make spotting differences effortless.
Yes, security is our priority. All image comparison is performed locally in your web browser using HTML5 Canvas and JavaScript. Your images are never uploaded to or stored on our servers.
Yes, our tool supports comparing images of different resolutions. However, for the most accurate visual pixel difference mapping, we recommend comparing images with the exact same dimensions to avoid misalignment.
You can compare standard web image formats including WebP, PNG, JPG/JPEG, and GIF files.
