Frequently Asked Questions

What is an ICO file used for?

ICO files are primarily used as favicons for websites and as application icons on Windows operating systems. They can contain multiple images at different sizes to accommodate various display resolutions.

Which sizes should I include in my ICO file?

For most purposes, including 16x16, 32x32, and 48x48 pixels is sufficient. For high-resolution displays, you may want to include 64x64, 128x128, and 256x256 sizes as well.

Is there a file size limit?

There are no artificial limits, but very large images may take longer to process depending on your device's capabilities. For best results, use PNG images under 5MB.

Can I convert other image formats to ICO?

This tool specifically converts PNG images to ICO format. If you have images in other formats (JPG, SVG, etc.), you should first convert them to PNG using an image editor.

How do I use the ICO file I created?

For website favicons, upload the ICO file to your website root directory and add the appropriate HTML link tag. For application icons, use the ICO file as your application icon in Windows.
