XnView Software

Thank you for your support. Does the quality of a JPEG file deteriorate if I embeed metadata in it with XnView?

Hello,
Where does XnView MP store the metadata information? Are metadata embedded in the JPG files themselves? or, is there a catalog file/database (as in Lightrooom) that holds all the information and that can be exported and re-imported if needed after a fresh Linux or XnView install?

Thank you ...
