Convert PNG to Favicon

Drop a PNG, get a multi-size favicon.ico ready to ship. We render entirely in your browser — your image never touches a server.

The output is a single .ico file containing 16, 32, 48, 64, 128, and 256 px variants. Every browser and OS picks the right one.

Transparency is preserved. Color profiles are normalized to sRGB so your icon renders identically across platforms.
