Allume Systems has released StuffIt Deluxe 10, its data compression, access, and management tool for Mac OS X.

This release features patent-pending JPEG compression technology, which lets users compress JPEGs and photos up to 30 per cent without losing image quality.

Until now, images have had to be reduced in quality in order to be reduced in size.

StuffIt's JPEG compression technology also allows users to view thumbnails of archived JPEGs without having to decompress the archive.

"StuffIt's ability to compress JPEG images and photos - without reducing image quality - represents a significant innovation in the field of data compression," said Matthew Covington, director of the StuffIt product line.

StuffIt Deluxe's tight Tiger tweaks

Spotlight Importer allows Spotlight to index file names for items stored inside StuffIt, Zip, and Tar archives. When the user performs a search, Spotlight will now list all the archives on the user's computer that contain files that match the search terms.

StuffIt Deluxe 10 also supports Automator, so users can compress and expand StuffIt, Zip, and Tar archives as part of their Automator workflows.

The product also contains StuffIt SEA Maker, a tool to build self-extracting packages that can be expanded to their choice of place on a recipient's computer. Users can even add a splash screen and text dialogue to their distribution.

StuffIt Express users can also create dropboxes to send and retrieve files from a .Mac iDisk.

The product costs $79.99 and is available now. Registered users of StuffIt Deluxe or StuffIt Standard can upgrade for $29.99 until March 31, 2006.
