What size should a favicon be?
The required size is 32×32 pixels. Standard website favicon at 32×32 pixels. Always use PNG format for transparency support.
Should I use PNG or JPG for icons?
Always use PNG for icons and app logos. PNG supports transparency and preserves sharp edges that are critical for small icon sizes.
Can I resize any image to a favicon?
Yes, but icons look best when designed at the target size (32×32). Complex photos may lose detail at small sizes. Simple graphics and logos work best.
