IcoFX VS Img2icns

If you're looking for an icon editor, there are many available, such as IconWorkshop, Icofx, and Iconion, but I haven't tried any of those. Source: 10 months ago

If this is only meant to make an existing game icon a Big Sur compatible one, https://img2icnsapp.com can do that automatically by dragging and dropping the icon into a template and saving it as an .icns file…. Source: 4 months ago

There is this simple app that lets you do that, but the folder option is behind a paywall If you don't want to buy it, I could try making it for you once I get home. Source: 11 months ago

Thanks for providing the customizer! I like the logo but immediately made the background darker to increase visibility on my Mac dock. I used image2icon in order to convert the provided .png file to .icns, otherwise it wouldn't size correctly for the dock to match other icons. Source: 11 months ago

Image2Icon (freemium) - converts normal pictures to the .icns format of macOS to set them as icons for apps, folders, etc. Brew install image2icon, Mac App Store. Source: over 2 years ago
