Questions
Does Visual Image Diff upload my screenshots?
No. Both images are decoded and compared locally in your browser. The diff image is generated on your device.
Can it compare images with different dimensions?
Yes. Utilumo compares the full combined canvas and marks pixels outside either image as different.
What does the threshold control do?
Threshold controls how large a pixel-channel difference must be before it is highlighted in the diff view.
Can I download the diff result?
Yes. The highlighted difference view can be downloaded as a PNG file.
Does Utilumo upload my input?
No. This tool is designed for local browser processing and does not send your input to a server.
Do I need an account?
No. Utilumo tools are built to work without accounts or sign-in.
