Sizes for a favicon
The favicon option packs 16, 32 and 48 pixels into one file, which covers browser tabs and shortcuts. Choose all sizes for a Windows app icon.
Start with a square image
Icons are square, so non-square images are cropped around the center, or fitted whole with transparent edges if you choose that. Start from at least 256 pixels for clean results. Simple shapes work better than detail at 16 pixels.
Formats and limits
Up to 50 files work in one go. Each can be 100 MB, and the whole batch 300 MB, or 25 files on a phone. Transparency is kept.
