Yes, for compression and squaring. Before the app replaces any image, it saves a backup of the original, and you can restore it in one click. Restore is free and doesn't use actions. It rolls back one optimization at a time, so an image optimized twice is restored in two steps.
Two things restore can't bring back:
file names — renaming changes the image URL permanently;
backups after uninstall — originals are kept for 14 days after you uninstall, then removed.
If something doesn't look right after a run, chat with us before changing anything — we'll help you get the originals back.
