Download the latest version 0.26b, 334 kB (2004-06-11). As I happen to use less and less frequently the Windows operating system, the work on this program is frosen. This is probably the last release, regardless of what may be written in the documentation.

This software is officially an "abandonware" - no longer developped neither supported.

About jpeg-Diet

The JPEG compression format is very widely used for digital pictures. It offers good image quality and small filesize and is the recommended format for photographies.

jpeg-Diet creates multiple copies of your pictures with different quality settings, resulting different filesizes. That allows you to choose the best ratio quality/filesize for every image that you would publish on your website, blog or gallery, or mail to your friends.

Check out an excellent freeware picture viewer that has very nice features: IrfanView. I use it all the time. The only feature it lacks is a multiple-quality-resampling from one source file. That's why I wrote jpeg-Diet.

This help file is rather brief, because the intended audience has some basic knowledge.

This software is based in part on the work of the NetPBM community and of the Independent JPEG Group.

Settings

Right-click on a JPEG-picture in your explorer and chose SendTo > jpeg-Diet. The program will create multiple copies of your file, with different quality settings, defined by you in an algebric regression.

Here are the main settings:

• Source file - the file to copy and process, it is already selected, or use the browse [...] button to change it.
• Resample - high quality resizing of the image, select less than 100% to reduce, more than 100% to enlarge; note that enlarging may take a long time.
• Highest quality - the (starting) best quality you wish to produce; may not exceed 100%; high values make larger files, often even bigger than the original.
• Lowest quality - the (ending) lower limit for the quality; should be less than the highest quality; values below 45% rarely give good results, and values below 12% may pop-up a complaint.
• Decrementation - the step quality (difference) to substract for every next copy. If you chose 6%, with a HQ=85% the program will create files with quality 85%, 79%, 73%, 67%, 61% etc.
• Progressive - a format often used for Internet, may not work with some very old software.
• Grayscale - uses 256 shades of grey to render an image, replacing the colors by their corresponding intensity in gray and the file is always smaller.
• Optimize - a slightly slower conversion that produces slightly better quality.
• The links Readme, Settings and Website open respectively this (local) help file, the settings jpeg-diet.ini and my website.

Advanced settings

There are some options that you can tweak in the file jpeg-diet.ini. Much more are to come in the next version, so stay tuned.

• lang - select the language of the interface. The value must correspond to an existing [section] in jpeg-diet.ini, for example English or Bulgarian. You can modify the language strings or add a new language.
• splash - controls the beautiful splash screen when jpeg-diet starts, set here 1 to enable or 0 to disable. The picture is the file lib\splash.bmp in the program directory and you may replace it - why not put a photo of your kids. I'll try to add more nice splash screens for download in the near future.
• targetfolder - the directory where to save the generated pictures. Default (if empty) is tmp in the program directory; here you can change it, add a complete path without trailing slashes. jpeg-Diet will create there a subdirectory for every processed image, containing all copies.
• AskToOpenFolder - after the generation of the pictures, jpeg-Diet asks if you wish to open the folder in Explorer. Set it to 0 to disable this feature, 1 to enable it.
• More to come soon, this will provide a very flexible way to add a number of user-defined commands for interaction with other utilities.
