iCR is iCorner Radius and it might be the Mac’s ultimate one-trick pony utility because, well, you know. One trick. As the name implies, iCorner Radius puts a rounded radius on any image. It looks like it’s made for application icons (similar to those for iPhone and iPad apps) but it works for any image or photo.
The way iCorner Radius works is typical Mac. Drag and drop onto the app the image whose corners you want to round. Select or set the radius you want. Click Save and you’re done.
You might want a few more features to round out this app that rounds out photo and image corners, but there are none. It’s a big time saver and though you could do the same thing in Photoshop, with iCorner Radius you’ll get change back from a dollar while Photoshop’s monthly subscription goes on forever.
Considering that iCR actually has a price tag, I’d go for a couple of additional and related features. For example, borders and stroke width options would be handy. But if all you want is evenly rounded corners on an icon or image or photo, iCorner Radius does the deed.
