Understanding WEBP and AVIF Formats

Learn about the source and target file formats to understand what happens during conversion.

Source Format

WebP Image

image/webp

WebP is a modern image format developed by Google that provides both lossy and lossless compression for web images. It typically achieves 25-35% smaller file sizes than JPEG at equivalent visual quality, and also outperforms PNG for lossless compression. WebP supports alpha transparency and animation, making it a versatile replacement for JPEG, PNG, and GIF on the web.

Advantages

  • Superior compression efficiency compared to JPEG and PNG
  • Supports both lossy and lossless compression, transparency, and animation
  • Widely supported in modern web browsers including Chrome, Firefox, Safari, and Edge

Limitations

  • Not universally supported in older software and image editors
  • Lossy WebP can produce different artifact patterns than JPEG at very low quality
  • Limited adoption in print and professional photography workflows

Common Uses

  • Optimized web images for faster page load times
  • Replacing GIF animations with smaller file sizes
  • Progressive web applications and mobile content delivery

Target Format

AVIF Image

image/avif

AVIF (AV1 Image File Format) is a modern image format based on the AV1 video codec, offering significantly better compression than JPEG and WebP. It supports both lossy and lossless compression, HDR, wide color gamut, alpha transparency, and animated sequences. AVIF is developed as a royalty-free open standard by the Alliance for Open Media.

Advantages

  • Superior compression efficiency, often 50% smaller than JPEG at equivalent quality
  • Supports HDR, wide color gamut (10-bit and 12-bit), and alpha transparency
  • Royalty-free and open standard with growing browser support

Limitations

  • Encoding is significantly slower than JPEG or WebP
  • Not yet universally supported in all browsers and image editors
  • Maximum image dimension limitations in some implementations

Common Uses

  • Next-generation web image optimization for bandwidth savings
  • High-quality HDR image delivery on supporting platforms
  • Progressive replacement for JPEG and WebP in web applications
