We have compiled a set of actions in Photoshop that will take your iTunesArtwork.jpg or app512.png and output all the icons necessary for either iOS or Android including rounded corner options.
There are two files attached, the actions and a script - Please place the files in their respective directories:
Windows
.atn C:\Program Files\Adobe\Adobe Photoshop CS6 (64 Bit)\Presets\Actions
.jsx C:\Program Files\Adobe\Adobe Photoshop CS6 (64 Bit)\Presets\Scripts
Mac OS X
For OSX you need to look for the Actions and Scripts folder in Applications/Photoshop/Presets/.
To use the actions you will first need to load them. Open the Actions panel by pressing Alt+F9 and the click the drop-down on the toolbar. Select Load Actions then use the file browser to locate the .atn file you coped above.
Now you should see a folder in your actions list called App Icons with a list of options.
Now all you need to do is open your iTunesArtwork.jpg or app512.png, highlight the desired action then hit the Play button at the bottom of the Actions panel.
Once the action has completed on your screen, a pop-up will appear to save the files.
- Browse to select the folder location
- Leave the prefix blank
- Visible layers only checked
- Trim layers checked
Finally click run and your icons will be produced!
