Drag your files here
or click to pick them from your device
Click the upload area or drag your ICO file straight onto it. You can drop several at once if you need to convert them all.
The output format is already set to WEBP. If you added several files and want a different format for each, switch to the "A format for each file" option.
Conversion runs on your own device, so it starts instantly and never depends on your internet speed or on a queue at some server.
Hit Download and save your new WEBP file. If you converted several, you can grab them all together in a ZIP.
WEBP is far more compatible than ICO: virtually any device, program or website opens it with nothing extra installed. On top of that, WEBP compresses the content, so the result will weigh considerably less than the original. That is what matters when emailing it or publishing it online.

Yes. Drop in as many as you like and they will be converted one after another. When they finish you can download them individually or all together in a ZIP.
Yes, on Android and iPhone, with no app to install. Just open this page in your phone browser.
