Advantages of WebP over JPEG

  • Smaller file sizes (typically 30-50% smaller than JPEG)
  • Superior compression efficiency compared to JPEG
  • Better preservation of details at lower file sizes
  • Support for both lossy and lossless compression (JPEG only supports lossy)
  • Alpha channel transparency support (not available in JPEG)
  • Higher bit depth support (up to 12-bit vs JPEG's 8-bit)
  • Animation support (unlike static JPEG images)
  • Better color reproduction at similar file sizes
  • Wide compatibility with modern browsers and platforms
