Why convert JPG to ICO?
JPG is everywhere, but it cannot store transparency and its compression is decades old. ICO is the format for favicons and Windows icons, holding several sizes in one file.
What changes when you convert JPG to ICO
- ICO files are usually larger than JPG files, because ICO stores the image with less (or no) lossy compression.
- ICO is lossless: every pixel of the decoded image is preserved exactly.
