Frequently asked questions

What size should I choose?

32×32 is the most common size for favicons and desktop shortcuts; use 256×256 for a high-resolution app icon.

Is my image uploaded to a server?

No. The image is converted entirely in your browser using JavaScript - it never leaves your device.

Does the source image need to be square?

A square source works best - non-square images are stretched to fit the square icon canvas.

Can I include multiple sizes in one .ico?

This tool produces a single-size .ico. For a full multi-size favicon set, use the Favicon Generator instead.
