Features
Themes and imports
Browse themes, search your icon library, or import an image or ICNS file.
Undo and restore
Undo the latest change or restore an app or folder’s original icon.
Icon changes you can reverse
No SIP changes
NyaIcon never asks you to disable System Integrity Protection and does not modify sealed system app bundles.
Approved app Helper
Every app icon change uses NyaIcon's approved IconServices Helper. A direct change to one ordinary folder stays local; type-wide changes use the Helper. macOS may ask once for approval.
Backed up and reversible
NyaIcon preserves the cache data it replaces so you can restore original icons later.
Your imports stay local
Images, ICNS files, and icon backups remain on your Mac and are not uploaded.
