WEBP → ICO

Learn about the formats: What is WEBP? What is ICO?

Convert WEBP raster images into ICO files instantly with our online tool. This conversion is essential for developers and designers creating website favicons.

WEBP is a modern raster format optimized for web delivery, often utilizing lossy compression to keep file sizes small. ICO is a traditional raster format designed specifically for Windows application icons and website favicons, which typically requires uncompressed or lossless pixel data. When you convert from WEBP to ICO, the file container changes to support multi-resolution icon structures.

Because WEBP uses lossy compression, any detail already discarded during the original WEBP creation cannot be recovered during the conversion to the lossless ICO format.

Tips

Crop your WEBP image to a square aspect ratio before converting to avoid distortion in your ICO favicon.
Expect the output ICO file size to be larger than the source WEBP because ICO stores multiple resolution layers.
Ensure your source WEBP has a transparent background if you need a transparent ICO favicon.

Common use cases

Creating a website favicon from a modern WEBP logo asset.
Packaging web graphics into Windows application icons.
Updating legacy desktop software branding with modern web assets.

− DRM-protected files may not convert

Frequently asked questions

No. Since WEBP is a raster format that often uses lossy compression, any data lost prior to conversion cannot be restored when moving to ICO.

ICO files often contain multiple embedded resolutions and formats within a single file, making the final size larger compared to a single compressed WEBP.

Yes, alpha channel transparency from your source WEBP raster image is preserved in the resulting ICO file.
