Frequently Asked Questions

Why do I need multiple ICO sizes?

Different operating systems and contexts use different sizes: 16×16 for browser tabs, 32×32 for taskbar icons, 48×48 for Windows file icons, 64×64 for higher-DPI displays.

Can I include ICO in a single file?

ICO files can actually contain multiple sizes in one file. Our tool generates separate files for flexibility — use a tool like ImageMagick to merge them if needed.

Does transparency transfer to ICO?

Yes — ICO supports transparency, and PNG transparency is preserved in the output.

Is there a file size limit?

PNG files up to 10 MB are supported.
