About This Conversion
What is JPG?
JPEG (Joint Photographic Experts Group) is the most widely used image format on the web. It uses lossy compression to achieve small file sizes, making it ideal for photographs and complex images with millions of colors. However, JPG does not support transparency or animation, and repeated saving gradually degrades image quality due to its compression algorithm.
What is AVIF?
AVIF (AV1 Image File Format) is a cutting-edge image format based on the AV1 video codec. It delivers superior compression efficiency, supporting HDR, wide color gamut, 10/12-bit color depth, alpha transparency, and animation. AVIF typically achieves 50% better compression than JPG while maintaining excellent visual quality, making it the most efficient image format available today.
Why Convert JPG to AVIF?
- You want the best compression — AVIF achieves up to 50% smaller files than JPG at the same visual quality.
- You need HDR support — AVIF supports high dynamic range and wide color gamut for stunning visuals.
- You want future-proof images — AVIF is the emerging standard endorsed by Apple, Google, Mozilla, and Microsoft.
