Generate Multi-Size Favicon.ico & Web Manifest Icons
Modern browsers, iOS home screens, and Android PWAs expect different icon sizes and formats. Open the Format & Favicon mode in Image Studio to turn one square artwork into a binary 16/32/48px favicon.ico, 180px Apple Touch icon, 192/512px Android PNGs, and site.webmanifest.

Image Studio — favicon ico generator
Rather than renaming a single PNG to .ico, Image Studio writes a spec-compliant ICO directory header containing 16×16, 32×32, and 48×48 entries alongside ready-to-paste HTML <link> tags packaged in one ZIP download.
Quick tip: Start from a 512 × 512 px PNG or SVG with clean contrast so downscaled 16 × 16 tab icons remain crisp.
Frequently asked questions
Is the exported favicon.ico a genuine binary ICO container?
Yes. It packs 16×16, 32×32, and 48×48 icon directories into a valid .ico file.
