Frequently Asked Questions
What happens if the two images are different sizes?+
Both images are scaled down to match the smaller image's dimensions before comparing. If the two images have very different aspect ratios, this scaling can distort the comparison — for best results, compare images with the same aspect ratio.
What does the sensitivity slider control?+
It sets how large a color difference must be before a pixel counts as "different." Lower sensitivity flags only major changes; higher sensitivity flags even subtle ones.
Can I use this to check if two exported files are identical?+
Yes — a 0% difference result means the visible pixel content is identical, even if the file bytes differ due to compression.
