nconvert -overwrite -buildexifthumb problem

Postby dodfr » Wed Aug 01, 2012 9:53 pm


I wanted to recreate exif thumbnails of a bunch of jpeg but I noticed that nconvert also recompress the jpeg itself (with higher compression ratio) ... this is bad, is there a way to avoid this default way of work ? nconvert should not touch original jpeg image/compression if not explicitly requested.
