Frequently Asked Questions
Why convert PNG to ICO?
ICO is the standard format for Windows icons and website favicons. Browsers and operating systems require ICO format for favicon.ico files. Converting your PNG logo or image ensures it displays correctly as a browser tab icon, desktop shortcut, or Windows application icon.
What sizes does the ICO file contain?
Our converter generates a multi-resolution ICO file containing 16×16, 32×32, and 48×48 pixel images all in one file. This ensures your icon looks sharp at every size Windows or browsers may request, from tiny taskbar icons to larger desktop displays.
Will transparency be preserved in the ICO file?
Yes. The ICO format supports 32-bit colour with a full alpha channel. Any transparency in your PNG, including semi-transparent areas, is fully preserved in the converted ICO file, so your icon blends correctly on any background colour.
