FAQ

Why doesn’t Manael convert PNGs to AVIF?

AVIF encoding for PNGs is intentionally disabled to prioritize compatibility, encoding speed, and alpha channel handling. PNGs will still be converted to WebP when the client supports it.

See the Supported Formats page for more details on the conversion table.

Can I use an Amazon S3 bucket URL as the -upstream_url?

Yes, as long as the S3 bucket is publicly accessible or accessible from the network where Manael is running.

Does Manael cache the converted images?

No. Manael acts purely as a stateless processing proxy. Please use a CDN in front of Manael for caching.
