Calculation Logic

The tool draws your source image to Canvas, creates PNG image data for each selected size, then packages those frames into a Microsoft Icon format .ico binary.

Modern browsers and mainstream desktop systems generally support PNG-encoded frames inside ICO files, preserving transparency while keeping favicon files compact.

FAQ

What is an ICO file used for?

Its most common use is favicon.ico for websites. It can also work for desktop icon use cases that accept standard ICO files.

What size should my original image be?

Use at least 256ร—256 pixels, preferably a transparent PNG. The tool resizes it to your selected favicon sizes.

Are my uploaded images kept on your servers?

No. Reading, resizing, and ICO packaging all run locally in your browser.

Can this create multi-size ICO files?

Yes. Select multiple sizes and the tool writes them into one ICO file.
