Frequently Asked Questions
What is an ICO file used for?
The ICO format is primarily used for computer icons in Microsoft Windows. On the web, it is widely used for 'favicons' (the small icon displayed next to your website's name in a browser tab).
Which size should I choose for a website favicon?
For standard website favicons, the 32x32 pixel size is highly recommended as it displays perfectly on standard and retina screens.
Why did my image get squished?
ICO files must be perfectly square (e.g., 32x32 or 256x256). If you upload a rectangular image, the tool will squeeze it to fit the square grid. For best results, crop your image into a square before converting.
