About PNG to ICO Converter
ICO is the icon format used by Windows and by website favicons. This tool wraps your image as an ICO that keeps transparency, scaling it down to 256 pixels if needed since that is the icon maximum. A square source image gives the best looking icon.
Frequently Asked Questions
What size should my PNG be?
A square image works best. Larger images are scaled down to 256 pixels, which is the maximum size an icon supports.
Can I use this as a favicon?
Yes. The ICO this tool produces works as a favicon.ico for a website or as a Windows icon.
Are my images uploaded to a server?
No. The conversion happens entirely in your browser using the canvas, so your image never leaves your device and nothing is stored.
