The format is common for photos and the standard built by the Joint Photographic Experts Group. If you send, transfer, or print pictures from the web, most likely the files are saved as JPG images. This file type supports 24 bits per pixel, 8 bits per pixel for green, blue and red, which makes it a truecolor displaying over 16,000,000 color tones. You may know this format as the most widespread compression type for pictures and the basis for most digital cameras. But technically it represents a lossy change that modifies the original image parameters.

JPEG image quality

It is not just a file format for storing visual data, but a sophisticated method of encoding and decoding images like quality settings.

This is why you will often see low, medium, and high-resolution options when exporting pictures. Each option reduces the compression ratio and improves the resolution of the photo. High-grade JPEGs are usually a good compromise between size and quality.

This is a very interesting methodology for saving graphic files. Very often, you can seriously save space by setting up your photos’ ratios well.
