Direct answer
Which views are available for image comparison?
Diff Anything provides side-by-side, overlay, swipe, blink, heatmap, and changed-pixel views. It aligns dimension changes on a shared canvas and reports changed pixels, similarity, error measurements, maximum channel change, and the bounds of the changed area.
Best for
Where this workflow fits.
- Reviewing UI captures and generated graphics between builds
- Finding subtle pixel changes that are hard to spot side by side
- Comparing private or unreleased artwork without an upload
No accounts, cloud comparison service, analytics, or telemetry.
Relevant capabilities
What Diff Anything brings to the job.
Practical workflow
From setup to a reviewed result.
Open both images
Choose two local image files; orientation-aware decoding prepares them for the same pixel coordinate system.
Choose a visual view
Start side by side, then use overlay, swipe, blink, heatmap, or changed pixels for the question at hand.
Tune the inspection
Use fit or true-pixel zoom, the transparency grid, and a 0–255 threshold to separate meaningful changes from tiny channel variation.
Read the measurements
Review changed pixels, similarity, mean and RMS error, maximum channel delta, dimensions, and changed bounds.

Questions about image diff tool.
Which views are available for image comparison?
Diff Anything provides side-by-side, overlay, swipe, blink, heatmap, and changed-pixel views. It aligns dimension changes on a shared canvas and reports changed pixels, similarity, error measurements, maximum channel change, and the bounds of the changed area.
Which image-diff views are available?
Side by side, overlay, swipe, blink, heatmap, and changed-pixel views are available in the same workspace.
Can Diff Anything compare images with different dimensions?
Yes. It aligns them at the top left on a shared transparent canvas, so the added or missing area remains part of the pixel comparison.
What image-diff measurements are reported?
The workspace reports changed-pixel count and ratio, similarity, mean error, root-mean-square error, maximum channel delta, source dimensions, and the bounds of the changed area.
Are the images uploaded?
No. Image decoding, visual views, thresholds, and measurements run locally in Diff Anything.
