About ICO Converter
An ICO file is the icon format used by Windows and website favicons. Drop in a PNG, JPG, or WebP and this tool builds an ICO that keeps transparency, scaling the image down to the 256 pixel icon maximum if needed.
Frequently Asked Questions
What makes a good icon?
Use a square image with a simple, bold design. It is scaled to 256 pixels or less, so fine detail may not be visible at small icon sizes.
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.
