WebP Image Format
Modern web image format developed by Google
What is WebP?
WebP is a modern image format designed to provide smaller file sizes while maintaining good image quality. It can support both lossy and lossless compression as well as transparency.
When to use WebP
- Web images — photos and graphics
- When you need smaller files than JPG or PNG
- Images that need transparency but should stay small
- Modern websites targeting current browsers
Advantages
- 25-35% smaller than JPG at equivalent quality
- Supports both lossy and lossless compression
- Supports alpha transparency
- Supports animation
- Faster encoding than AVIF
Disadvantages
- Not supported by very old browsers (pre-2020)
- Less universal support than JPG (though all modern browsers support it)
- AVIF can provide even better compression
Transparency
WebP supports full alpha transparency in both lossy and lossless modes. This makes it a strong replacement for PNG when smaller file sizes are needed.
Browser compatibility
WebP is supported by all modern browsers including Chrome, Firefox, Safari, Edge, and Opera. It is the recommended format for web images in 2024 and beyond.
WebP vs other formats
WebP vs JPG: WebP is 25-35% smaller at equivalent quality and supports transparency.
WebP vs PNG: WebP can match PNG quality at significantly smaller file sizes.
WebP vs AVIF: AVIF offers better compression but slower encoding. WebP is a good balance of size and speed.
