Why WebP?
WebP is a modern image format developed by Google that provides both lossy and lossless compression for images on the web. Here are some benefits of using WebP:
- Smaller File Size: WebP images can be up to 30% smaller than JPEGs and PNGs with no noticeable loss in quality, resulting in faster page load times.
- Transparency and Animation: WebP supports transparent backgrounds like PNG and animated images like GIF, making it a versatile choice.
- Improved Compression: WebP offers better compression algorithms compared to traditional formats, allowing for high-quality images with lower storage requirements.
Why AVIF?
AVIF (AV1 Image File Format) is a cutting-edge image format derived from the AV1 video codec, offering even better compression than WebP. Here’s why AVIF is beneficial:
- High Compression Efficiency: AVIF can reduce image sizes by up to 50% compared to JPEG, while maintaining similar or even higher visual quality.
- HDR Support: AVIF supports High Dynamic Range (HDR), allowing for more vibrant and detailed images, especially on modern displays.
- Advanced Features: It includes support for transparency, animation, and a wider color gamut, making it suitable for various types of web content.
