I'm doing convert -resize 800x800 -compress jpeg -quality 90 [filename].tif [filename].jpg, run through a for loop in bash to get everything. Man, *slow*, though, especially on the 45MB TIFFs. *g*
My only problem is that the old set of JPEGs was listed as "compressed at a 10:1 ratio", and a day of image research doesn't even tell me if that's a meaningful or repeatable metric. Some websites imply that it's not. Certainly the ImageMagick "quality" switch is IM-specific. But if there's a way to make ImageMagick "compress at a 10:1 ratio" -- or even if that's a meaningful command -- I can't find it.
