Supported Formats

Review supported source formats, skipped formats, and output behavior for WebP and AVIF.

Version 1.0.1 centralizes source support in the ImageFormat helper so queue, upload automation, and manual actions agree.

Supported sources

  • JPEG: WebP and optional AVIF derivatives.
  • PNG: WebP and optional AVIF derivatives.
  • WebP: source optimization and optional AVIF derivative.

Skipped sources

  • SVG files are skipped for safety.
  • Animated GIF files are skipped to preserve animation.
  • Unreadable files are skipped.
  • Excluded MIME types, filenames, paths, or size ranges are skipped.
  • Unsupported formats receive a clear status message.

Output formats

WebP is the primary output format. AVIF is optional and only useful when the server can read and write AVIF reliably.
