Common questions about PNG to ICO Converter.
No. The conversion runs entirely in your browser, so your file never leaves your device.
Yes. The ICO keeps the full alpha channel, so transparent areas stay transparent.
Each ICO includes the standard sizes of 16, 32, 48 and 256 px, leaving out any that are larger than your image so nothing is blurred by enlarging. A square PNG of 256 × 256 px or more gives all four.
Icons are square, so the whole image is kept and centered with transparent padding. For best results, start with a square PNG.
Yes. Save it as favicon.ico at your site root. If you need a full set of favicon, Apple touch and Android icons plus the HTML tags, use our Favicon Generator instead.
It works in all current browsers, Windows Vista and later, and macOS. Very old software such as Windows XP may not read icons that use PNG data inside.
