Frequently Asked Questions

What is an ICO file?

ICO is a file format for computer icons in Microsoft Windows. ICO files contain one or more small images at multiple sizes and color depths, allowing applications to use the most appropriate size for different display contexts.

What sizes should I include in my ICO file?

Common sizes include 16x16 (toolbars), 32x32 (menus), 48x48 (desktop), and 256x256 (high DPI). For favicons, 16x16, 32x32, and 48x48 are typically sufficient.

Can I create favicons with this tool?

Yes! ICO is the standard format for website favicons. Simply generate an ICO file with common sizes (16x16, 32x32, 48x48) and save it as favicon.ico in your website root.

What's the difference between single and multiple files?

Single file mode creates one ICO file containing all selected sizes (recommended for most uses). Multiple files mode generates separate ICO files for each size, useful for specific requirements.

How do I use the resize methods?

Fit maintains aspect ratio and fits within the size, Cover fills the entire size (may crop), and Stretch forces exact dimensions (may distort).
