ICO to WEBP Converter

Convert ICO files to WEBP. Batch, free and without uploading.

This tool converts ICO files to WEBP. ICO is the format for Windows icons and website favicons. It holds the same icon at several sizes, such as 16, 32, 48 and 256 pixels, in one file.

WEBP is Google’s format for the web. It stores the same image about 25–35% smaller than JPG and supports transparency and animation. WEBP is lossy, and you choose the quality with the slider. For photos, 80–90% makes the file much smaller with a loss you won’t notice.

Conversion happens inside your browser; your files are never sent to a server.

How to use

1. Drag and drop your ICO files, paste them from the clipboard, fetch one from a link, or use "Choose files".
2. Set the quality and, if you like, a maximum size.
3. Press "Convert" and download the WEBP files one by one or as a ZIP.

Frequently asked questions

Will converting to WEBP reduce quality?

WEBP is lossy, but at 85–90% quality the difference isn’t visible. Lower quality means a smaller file.

How many files can I convert at once?

There is no limit. Select hundreds of files together and download the results as one ZIP.

Are my files uploaded anywhere?

No. Your ICO files are converted to WEBP inside your browser and never sent to a server.
