Transparency
The target can store an alpha channel, but converting an opaque image does not create transparent areas. Removing a background is a separate editing step.

Lossless pixels, lossy pixels and reversible recompression of an eligible JPEG bitstream are separate modes. Exact JPEG reconstruction requires its reconstruction data, not just matching rendered pixels. Quality defaults to 80; adjust it in Advanced options. File size depends on the image and encoder.
