02 · The honest pitch

Why PNG to ICO Converter?

ICO files bundle multiple resolutions into a single file so browsers and operating systems pick the right size — a 16×16 icon for a browser tab, a 256×256 icon for Windows Explorer at large-icon view. Most "favicon generators" force you to sign up or embed tracking scripts. This one produces a raw .ico file from your source PNG, with every standard size in one pass, and nothing more.

Frequently asked questions

256×256 or 512×512 at minimum. Starting at a larger size means every downscaled layer looks crisp. Upscaling from a smaller source produces blurry small icons.
