Favicon generator

Generates the full favicon set from a single PNG or SVG: ICO, PNGs at all standard sizes, apple-touch-icon.

Takes a square image (PNG, JPG, WebP, SVG) and returns a ZIP archive with the full favicon set: favicon.ico (multi-size, 16/32/48 px), favicon-16.png, favicon-32.png, favicon-48.png, apple-touch-icon.png (180 px), android-chrome-192.png and android-chrome-512.png. The archive also contains a ready HTML snippet with the right <link> tags and sizes attributes — paste it into <head>. The ICO is built on the fly: PNG chunks packed with an ICO header and directory entries. Runs in the browser, no upload.
