JPEGmini Now Available for Mac: Put Your iPhoto Library on a Diet

Back in August we featured a service called JPEGmini, which gives anybody the ability to shrink their photos up to 5-times in size without any visible quality difference — a substantial claim, but one that the service seemed to live up to quite well (we use it regularly).
In the original post we even put a side-by-side comparison of a photo we had shrunk down to 4.1-times its original size, and people were generally impressed by the outcome. Some commenters were even hoping for a Photoshop plugin.

Instead of a Photoshop plugin, however, JPEGmini has decided to branch out from the web by offering a Mac application that will perform this same shrinking service to entire photo libraries. People cramped for disk space — and who don’t want to spring for a new HDD — can buy the app for $19.99 and compress their library up to 5-times without any visible change in the photos themselves.

Sure, professionals probably won’t want to do this; compression is compression, and “visible” is most definitely in the eye of the beholder. But those who aren’t concerned with losing a little bit of hard-to-notice quality while gaining a lot of space will be glad JPEGmini for Mac is available.

    If you’re a GIMP user, the RIOT plugin does an amazing job of crushing jpg’s down in size with minimal visual loss as well:

    Definitely worth checking out (as it’s integrated as a save option in GIMP).

    Color me unimpressed.  I chose a night star exposure.  Start to compress the JPEG too much, and artifacts show up.

    Photoshop jpeg at quality 12 (i.e. uncompressed) is 460k for a 633×950 image.  Jpeg level 10 is 171k; level 8, 88k.

    Jpegmini spit out a file that’s 238k.  It’s better than level 8 compression, but the same as level 10 compression.  I layed the files over each other with a blending mode of difference.  At 500% magnification, jpeg level 10 looks like jpegmini.  Exception jpegmini is bigger.
