Will I lose quality converting PNG to ICO?
No. ICO is lossless, so the converted image keeps every pixel exactly as it was decoded from the PNG file.

Yes. Drop as many files as you like; they are converted in parallel and can be downloaded individually or as a single ZIP.
Are my PNG files uploaded?
No. The conversion runs locally in your browser, so your images never leave your device.
Does it work on iPhone and Android?
