A Macintosh kindwordware drag-and-drop applet by Sam Bushell.
To JPEG lets you convert image files into JPEG files with a single step. Just drop one or more image files onto its icon, wait a few moments, and you'll find JPEG-compressed versions right next to them. Open To JPEG and choose Preferences... to configure how files are compressed and saved. You can also convert pictures directly from the clipboard, from picture clipping files, or from any file type you have a QuickTime graphics importer component for.Download To JPEG 1.0 (160K)
To JPEG requires System 7.0 or later. It works much more nicely if the Thread Manager is installed, and can convert many more kinds of files if QuickTime 2.5 is installed. (The Thread Manager is built into System 7.5.)
If Internet Config 1.1 or later is installed, To JPEG consults it to find out the preferred type and creator for ".jpeg" files. If not, they're saved with file type JPEG and creator JADE, because Eric Shieh's Jade is my current JPEG viewer of whim.
To JPEG is kindwordware: if you appreciate it, please send me a kind word.
I wrote To JPEG partly because of my frustration at having to go through a tedious Open/Save cycle to convert JPEGs, and partly because of feedback I got for Progressify, a similar applet which converts between sequential-display and progressive-display JPEG files without loss. I'd like to thank all the people who sent me kind words for Progressify.
To JPEG uses a free JPEG library written by the Independent JPEG Group; it's essentially a Macintosh port of the cjpeg program included in that library. Here, let me say it again: "this software is based in part on the work of the Independent JPEG Group. Permission for use of this software is granted only if the user accepts full responsibility for any undesirable consequences; the authors accept NO LIABILITY for damages of any kind."
To JPEG is also based on DropShell 2.0 by Leonard Rosenthol, Marshall Clow and Stephan Somogyi.
