Small files. Honest results.

Compare the decoded export, not an approximation. A quality setting is an encoder parameter, not a percentage of visual fidelity. Exports normalize orientation and use web/sRGB color; camera metadata is not retained. HDR and exact color-profile preservation are not supported.
