Frequently Asked Questions

What size should my PNG be for ICO conversion?

Upload a square PNG at least 256x256 pixels. The converter will automatically scale it down to common favicon sizes (16x16, 32x32, 48x48, 64x64) and include all sizes in one ICO file.

Can ICO files contain multiple sizes?

Yes! That's the main advantage of ICO format. One .ico file can contain the same icon at multiple resolutions, and browsers/systems will use the most appropriate size.

Do I need ICO for my website favicon?

While modern browsers support PNG favicons, ICO format ensures maximum compatibility with older browsers and provides better scaling across different contexts (browser tabs, bookmarks, desktop shortcuts).

Does ICO support transparency?

Yes, ICO format supports transparency. Your transparent PNG logo will maintain its transparency in the ICO file, perfect for favicons that blend with browser themes.
