ORF does not support alpha transparency. Transparent APNG areas must be flattened onto a background color.
Animated, sequence, or multipage inputs need explicit frame/page handling.
Converting APNG to ORF decodes the source image and writes a ORF output. Use this route when ORF is a better fit for compatibility, file size, editing, or delivery.
Quality behavior depends on ORF compression: depends.
Choose conversion targets based on ORF compression, transparency, animation, metadata, and compatibility requirements.
Known metadata support: PNG chunks.
Raw converter support depends on camera model.
