❓ Frequently Asked Questions

What is ICO format?

ICO is the Windows icon file format that can contain multiple sizes of the same icon. It's primarily used for Windows application icons and website favicon.ico. A single ICO file can embed icons at multiple resolutions from 16x16 to 256x256.

What image formats can I convert to ICO?

You can convert PNG, JPG/JPEG, WebP, GIF (first frame), BMP, and SVG files. Images are automatically scaled to square and converted to ICO format for optimal display quality.

Can I use the converted ICO as a website favicon?

Yes. Save the generated ICO as favicon.ico in your website root directory and add <link rel="icon" href="/favicon.ico"> to your HTML. We recommend selecting 16x16, 32x32, and 48x48 sizes for best compatibility.

Why do I need multiple sizes?

Different scenarios require different icon sizes: taskbar uses 16x16 or 32x32, desktop uses 48x48 or 64x64, large icon view uses 96x96 or 256x256. A multi-size ICO ensures your icon looks sharp in all contexts.
