Frequently Asked Questions

Why convert PNG to ICO?

Websites use an ICO file for the favicon shown in the browser tab, and Windows uses ICO files for app and shortcut icons. This tool makes one from your PNG.

Does it keep transparency?

Yes. The icon keeps the transparent background of your PNG, so it sits cleanly on any color.

What size will the icon be?

The image is kept at its size up to 256 by 256 pixels. Anything larger is scaled down to fit, which is the maximum an ICO supports.

Should I use a square image?

Yes. Icons are square, so a square PNG gives the best result. A non-square image is still packed, but may look stretched in some places that force a square.

Is my image uploaded anywhere?

No. The conversion runs entirely in your browser, so the file never leaves your computer and it works offline.

Does it work on a phone or tablet?

Yes, in any modern browser, with nothing to install.
