Generate a full favicon package — ICO plus every PNG size you need — from one image.
A square image, 512×512px or larger, works best
Supports: JPG, PNG, WebP • Processed securely, deleted after useA multi-resolution favicon.ico (16/32/48px), standalone PNGs at 16, 32, 48, 64, 128, 180, 192 and 512px, an apple-touch-icon.png for iOS home screens, and a text file with the exact <link> tags to paste into your <head>.
A square image at least 512×512px works best — logos or icons with simple shapes hold up better at 16px than detailed illustrations.
Modern browsers mostly use the PNG sizes and apple-touch-icon; favicon.ico is kept for older browser compatibility and search engine favicon display — including all of them covers every case.
Detailed logos lose clarity at very small sizes. Simplify your icon (bolder shapes, less fine detail) for a crisp result at 16×16.
