Logo Crunch uses computer vision to make multi-resolution favicons and app icons
It's very effective at generating the smaller resolution icons.Cons:
It adds a white or black background to your file depending on the file format.
I like the tool so much that I keep coming back to see if he fixed the background issue. I would suggest trying it out but it's not ready for a product in production like ours.Aaron Chiandet has used this product for one month.
