Frequently asked questions
How do I convert ICO to WebP?
Click “Choose Files” and select your ICO file (or drag it onto the page). WebP is already selected as the output, so just click Convert and download your WebP file when it’s ready.
Will I lose image quality?
WebP uses compression, but at the default 90% quality the difference is practically invisible. You can raise or lower the quality in Advanced settings.
Is it safe to convert ICO files here?
Your files stay on your device. Conversion runs inside your own web browser, so your files are never uploaded to our servers or anyone else’s. Nobody can see them, and nothing is stored after you close the tab.
Is the ICO to WebP converter free?
Yes, it’s completely free. There’s no sign-up, no watermark and no limit on how many files you convert. Each file can be up to 1 GB.
Can I convert several ICO files at once?
Yes. Add as many ICO files as you like and convert them in one go, then download them one by one or together as a ZIP file.
