What compression ratio is used for my photos in the software?

In normal mode, photo files are compressed to 85 DPI with a JPEG quality of 89. In professional mode, photo files are compressed to 150 DPI with a JPEG quality of 95.

DPI (Dot per inch) indicates a photo’s resolution. A digital photo is composed of pixels. A pixel does not have a clearly defined size. To represent the size of a pixel, it is necessary to know the resolution used to represent the pixel. Resolution defines the number of pixels by units of length (centimetres or inches).
