ICO / Favicon Generator
Online favicon generator: upload one image to get 9 PNG sizes from 16×16 to 512×512 plus a multi-resolution .ico, including apple-touch-icon and android-chrome sizes. Runs in your browser, zero upload.
Pick sizes：
.ico embeds the 16/32/48 sizes for maximum compatibility; other sizes ship as individual PNGs.
Upload a 512×512 (or larger) square image; non-square sources are centre-cropped automatically.
