My icons have a filled background:
- Some image formats don't support transparencies (for example .jpg files). If you want to create an icon with transparencies use an image format that supports them (i.e.: gif, png, tiff).
My images are not square, but when I convert them to icons they become square and their proportion change:
- Img2icns will maintain the proportion of all your icons, except for fav icons and iPhone icons because they need to be square for the use that is made of them. You can disable this behaviour inside the Img2icns preferencies.
