What's the difference between ICO and PNG?
expand_more
ICO (Windows Icon Format) is best for browser favicons and windows desktop icons that need multiple sizes in a single file. PNG (Portable Network Graphics) is best for screenshots, logos, ui elements, and any image requiring transparency or pixel-perfect accuracy. Key tradeoff: ICO's advantage is stores multiple resolutions (16x16 through 256x256) in one file so the os or browser picks the best size automatically, while PNG's advantage is lossless compression with full alpha-channel transparency — every pixel is preserved exactly.
