7.10.1 Options

#### 7.10.1.5 File/JPEG

JPEG allows to save files progressive. This is useful, if you want to use your files on a web page, because web browsers are able to load and display a progressive JPEG in parts.

The slider JPEG Quality controls the reduction of the JPEG compressor. A value of 100 means minimum compression and highest image quality, a value of 0 means maximum compression and lowest quality. If you save an image for displaying on the screen, a value of 70 is appropriate, for printing you should use 90. But pay attention: JPEG is lossy and you may loose image quality. Information about lossless JPEG editing can be found in chapter 5.5.2 "JPEG-Image in PhotoLine".

Usually the JPEG format saves color information with a lower quality than brightness. If High Quality is turned on, color information will be saved using the same quality.

JPEG files can contain EXIF data. EXIF data store the settings used when taking the photo: time, date, aperture, exposure, ... Apart from this they often contain a preview image, too. EXIF Preview Image: controls how to handle this thumbnail. Save New creates a new one on saving. Keep Existing keeps the EXIF data unchanged and stores them exactly the same way they were loaded. Don‘t Save deletes the preview image, if there is one.
