Compare Images
Compare two selected images side by side, with a swipe divider or a translucent overlay, or mark the pixels that differ in red and box each area that changed. Handy for before-and-after screenshots and for checking a build against its design.

What it does
Select two images in Finder and compare them side by side, with a swipe divider, or with the new one laid translucently over the old.
Difference marks the pixels that changed in red, boxes each area and says how many there are and what share of the pixels they cover.
The file modified earlier counts as the old one. Ignore subtle differences skips the invisible noise of compressed photos and exported screenshots.
Copy, save or pin the view you’re looking at, drawn at full size. Pop remembers the view you used last.
Install it

1From Settings
In Pop’s Settings › Actions, find “Compare Images” under Plugins at the top and click Install. It downloads from Pop’s GitHub release in a few seconds and works right away, without a restart.
2Or from the ring
Open All Actions on the ring and search for “Compare Images”. Plugins that aren’t installed are listed after your actions: click it to install, and it runs right away if it can handle what you selected.
3Then use it your way
Put it on the ring in Settings › Ring, give it a shortcut, or run it from Shortcuts and scripts with its link:
