AVIF

Enable optional AVIF generation when Imagick or GD can read and write AVIF images.

AVIF is optional and depends heavily on server support. Vacuum treats AVIF as a parallel derivative format.

When to enable AVIF

Enable AVIF when System Status confirms AVIF read and write support. If AVIF is unavailable, keep it disabled and continue using WebP.

Output behavior

  • JPEG, PNG, and WebP sources can be used for AVIF generation when supported.
  • Existing AVIF files are not overwritten blindly.
  • AVIF metadata is stored separately from WebP metadata.
  • Frontend delivery can prefer AVIF when available and fall back safely.

Quality

AVIF quality defaults to 60. Test image-heavy pages before lowering quality further, especially for product images, portfolio images, and artwork.
