Comparison settingsPixel threshold: 0

Images must have equal dimensions after EXIF orientation. Transparent pixels are composited on white. A pixel changes when any RGB channel differs by more than the threshold. This is a pixel comparison; compression and browser colour handling can affect results.

How it works

Choose two still JPG, PNG or WebP images with equal dimensions.
Choose your settings, then preview or process it.
Review the overlay or difference mask, then download the PNG difference image.

A few useful details

Comparison uses correctly oriented images, composited on white. Pink pixels mark changes exceeding your chosen RGB threshold. Images are not automatically resized or aligned. Browser colour handling and lossy compression can affect pixel differences.

Up to 15 MB and 6 megapixels per image; difference downloads are limited to 20 MB. File contents are not saved between visits.
