NovoIcons is the best icon extractor. It's simple and intuitive, but has more features than the competition. It can extract icons and export them into PNG, TIFF, GIF, JPG, or ICNS. 512×512 icons are fully supported.
While this version is over 2 1/2 years old, it still functions well. Version 2.0 is under way, but it is barely into development so it will be a long time until release.
- It's beautiful. NovoIcons has always looked great, and the future release will look even better.
- It works. NovoIcons extracts and exports icons how it should. Even the modern 512×512 icons starting in Leopard are supported and correctly exported.
- It supports batch export. Extracting each icon at a time is extremely time consuming. With NovoIcon's batch extractor, you can simply open a folder and have its contents' icons extracted.
