★ Formerly Unretina / Unretiner, this is the original, and most popular resize app for developers! (Name changed at Apple's request).
Develop iOS apps? Easily resize your @2x or -hd cocos2d images in seconds! Great for testing out non retina devices before the big painful export from Photoshop.
Supports .png .jpg .tif and .bmp.
To use simply drag @2x or -hd named images (or a folder containing the images) onto the application, choose an output folder and you are done!
Remember that Resizer is great for some images, but nothing beats recreation.
We've had some great requests for features for Version 2:
* AppleScript Support (Automatically convert a folder when files appear)
* Sharpness Filter
* Other (better quality) scaling methods
* Drop files onto icon
* Settings to default to same folder and hide the message box.
Let us know what you'd like to see!
