Convert PNG to a Favicon
A favicon is the tiny icon shown in browser tabs and bookmarks. Modern sites no longer need a single .ico file — they use a set of square PNG icons (16, 32, 48, 180, 192, 512) referenced from HTML. The fastest way to make one from your logo is to generate all those sizes at once from a single square PNG.
For a full icon set, use the Favicon Generator. To resize a single PNG, use the converter below.

Frequently asked questions
Do I still need a .ico file for a favicon?+
Not for modern browsers — they use PNG icons referenced in your HTML. A .ico is only needed for very old browsers.
What size should my source PNG be?+
Use a square image at least 512×512 so the largest icon stays crisp. Smaller sizes are generated automatically.
