Frequently Asked Questions
What sizes are included in the ICO file? +
The generated ICO file contains three sizes: 16x16, 32x32, and 48x48 pixels. You can also choose to include only specific sizes. These cover favicon display in browser tabs, bookmarks, and desktop shortcuts.
Can I use a non-square PNG as input? +
Yes, but the image will be scaled to fit a square aspect ratio. For best results, start with a square PNG. Non-square images will be resized proportionally and centered with transparent padding.
How do I add this favicon to my website? +
Place the .ico file in your website root directory and add this to your HTML head: <link rel="icon" href="/favicon.ico">. Most browsers also check for favicon.ico at the root automatically.
What is the maximum PNG size I should use? +
There is no strict limit, but icons are scaled down to 48px at most. Using a source image between 64x64 and 512x512 gives the best results. Very large images just take longer to process with no quality benefit.
