Which frame is used when converting an animated GIF to ICO?

The converter uses the first frame of an animated GIF. ICO files are static, so only one frame can be embedded. Choose a GIF whose first frame best represents the icon.

Does GIF support transparency in ICO files?

GIF supports 1-bit (on/off) transparency, which is preserved during conversion. For smooth semi-transparent edges, use a PNG or WebP source instead.

What ICO sizes are generated?

The tool generates 16×16, 32×32, 48×48, 64×64, 128×128, and 256×256 pixel sizes packed into a single .ico file.

Can I use the ICO file as a website favicon?

Yes. Place favicon.ico at your site root and add to your HTML . All browsers will recognise it.

Tips:

•Use PNG source files with transparency — the alpha channel is preserved in the ICO output
•A larger source image (512×512 or higher) produces sharper icons at every ICO size
•ICO files bundle multiple sizes (16×16 to 256×256) so Windows and browsers pick the best fit automatically
•For favicons, add <link rel="icon" href="favicon.ico"> to your HTML <head>
