Search all installed apps to find the one you want to fix up. Use filters to focus on apps in your Dock.
Restore original icons if you change your mind.
Keep your alternate icons across app updates entirely automatically.
Hide apps and icons you do not want to see to narrow down the list.
Import your own icons from disk and manage them with all the rest.
Replacicon is a native app built just for macOS, and it works great with Intel and Apple Silicon Macs.

As seen on...
Replacicon has been particularly useful for replacing some app icons that looked out of place in my Dock, mostly those that haven’t been updated to fit with the rounded square style brought from iOS with macOS Big Sur.
I'm not a fan of the uniform icon shape of recent macOS updates. It makes my dock feel boring. I still haven't settled on all of the new icons I'll be using, but I'm sure I'll be playing around with this app over the next week or so until I've tweaked to my liking.
If you want to quickly and easily change the app icons under macOS Big Sur or newer back to old or completely alternative versions, then this is it. This software searches multiple web sources for icons for all kinds of programs and assigns them with one click.
Thank you. I've been waiting too long for something like this.
