About the AVIF Format
AVIF is the newest and most advanced image format available today, based on the AV1 video codec developed by the Alliance for Open Media. It offers significantly better compression than both JPEG and WebP — producing files up to 50% smaller than JPEG at the same visual quality. AVIF supports HDR (High Dynamic Range), wide color gamuts, transparency, and animation. It represents the cutting edge of image compression technology.
AVIF was first released in 2019, based on the royalty-free AV1 video codec. It was developed by the Alliance for Open Media, which includes major tech companies like Google, Apple, Microsoft, Mozilla, Netflix, and Amazon. Browser support has been rapidly expanding since 2020.

About the WEBP Format
WebP is a modern image format developed by Google that provides superior compression for images on the web. It supports both lossy and lossless compression, transparency, and even animation — essentially combining the best features of JPEG, PNG, and GIF into a single format. WebP images are typically 25-35% smaller than comparable JPEG images at equivalent visual quality, making it an excellent choice for improving website loading speed.
WebP was introduced by Google in 2010 as part of their effort to make the web faster. It is based on the VP8 video codec technology. Browser support has grown steadily, and as of 2023, WebP is supported by all major browsers including Chrome, Firefox, Safari, and Edge.
✅ Advantages
- 25-35% smaller than JPEG at similar quality
- Supports both lossy and lossless compression
- Transparency support (like PNG)
- Animation support (like GIF)
- Excellent for web performance and Core Web Vitals
❌ Disadvantages
- Not universally supported in older software
- Some image editors still lack native WebP support
- Slightly slower to encode/decode than JPEG
