Defined in:

Overview

Re-encode all extracted images as HEIF/HEIC at the given quality level.

quality must be in 1..=100. Values outside this range are clamped and a warning is emitted. 80 is a reasonable default.

The encode path requires the heic feature; on builds without it, selecting this variant returns an EncodeFailed warning and leaves the image untouched.
