Frequently Asked Questions
Why not just rename a PNG to .ico?+
A renamed PNG is not a valid .ico file — Windows and many apps expect the real ICO container format with multiple embedded resolutions, which is exactly what this tool builds.
Which sizes are included?+
16, 32, 48, 64, 128, and 256 pixels, all packed into a single .ico file so the right size is used automatically wherever it's needed.
What is the best source image to use?+
A square image, ideally 256×256px or larger, with a transparent background for the cleanest result at every size.
