Convert ICO to WEBP
What is ICO?
ICO
ICO stores multiple bitmap images at various sizes and color depths (1-bit to 32-bit with alpha) in a single file. Designed for Windows application and website favicons. Contains multiple representations (16×16, 32×32, 48×48, 256×256) for different display contexts. Can store both BMP and PNG formats internally. Maximum 256×256 pixels per image. Supports transparency.
- ICO uses lossless compression for perfect quality image storage
- Opaque image data converts to WEBP without utilizing transparency features
- No transparency support—requires opaque backgrounds
What is WEBP?
WebP
WebP uses VP8 (lossy) or VP8L (lossless) compression, offering 25-35% better compression than JPG and PNG respectively. Supports full alpha channel transparency and animation. Maximum resolution 16,383×16,383 pixels. Developed by Google for web use. Smaller file sizes with comparable quality. Browser support now widespread. Ideal for web images requiring both quality and efficiency.
- WEBP uses lossless compression for perfect quality image storage
- Alpha channel transparency requires background color for ICO conversion
- VP8/VP9 codec provides better compression than JPEG at same quality
- Modern format—requires up-to-date software for compatibility
