I have converted a file to jp2 and do not know how to compress that file - because as far as I understand - that is where jp2 is really good, that it can be compressed a lot, and not lose quality.

I have seen some abbreviations for compressions but not a complete list.

Thanks

I am using the command prompt.

See http://www.imagemagick.org/script/jp2.php ; jp2 is lossless only if used with , which has some marginal space saving over a LZW/Zip TIFF.

Otherwise, you can get unexpected results: viewtopic.php?p=125169#p125169
