Why convert ICO files to WEBP format?

Converting ICO to WEBP helps reduce file sizes for web use, improves loading times, and preserves transparency with modern compression techniques.

Can all ICO icons be converted to WEBP without quality loss?

ICO files contain multiple resolutions and some have limited alpha support; conversion quality depends on these factors and chosen WEBP compression settings.

Is WEBP supported on all browsers?

WEBP is widely supported on modern browsers but may have limited or no support in some older browsers and legacy software.

Limitations

ICO files are designed for small icons, not large photographic images; conversion of large images may not be suitable
Transparency in older ICO files uses limited alpha or 1-bit masks, which may cause inconsistencies after conversion
Lossy WEBP compression can introduce visual artifacts depending on image type and settings
Some tools inconsistently handle PNG-compressed ICO entries and metadata, which may affect output quality
WEBP metadata and color profile support can vary between implementations, possibly impacting interoperability
