Read about how JpegQuality works on CodeProject.
Make a lower-quality copy of multiple JPEG files. This is useful when you have shot lots of high-quality, high-resolution images that are not important enough to store at their original size. These results are typical:
| Quality | Size relative to original |
|---|---|
| 95 | 50% |
| 90 | 30% |
| 80 | 20% |
| 70 | 15% |
| 60 | 12% |
| 50 | 10% |
| 40 | 9% |
| 30 | 8% |
| 20 | 7% |
| 10 | 5% |
| 5 | 4% |
- Windows XP or later

- To set the quality value, run
JpegQuality.exeand select a value from the drop-down. This value is saved to the registry for future use. - Drag-and-drop file(s) directly onto
JpegQuality.exe; or - Run
JpegQuality.exeand drag-and-drop file(s) where indicated. - New files will be saved in the same location as the originals, with
-XXappended, where XX is the quality factor.
