JPG file format information

Full NameJoint Photographic Experts Group
Mime Typeimage/jpeg
Opens WithPaint.Net, Photoshop

A JPG file is a compressed and highly efficient image file format whose aim is to store photographic-quality images using a fraction of the storage space compared to other lossy and non-lossy image compression methods available at the time.

The compression used by JPG encoders is "lossy", meaning image colours that are not perceptible to the human eye are discarded during the compression process. The removal of this colour data greatly reduces the size of the final JPG file with no discernible loss in quality.

Due to their compact and high-quality format, JPG files are one of the primary image formats used by websites, digital and phone/tablet cameras, and more. This widespread support means JPG files can be edited within most popular image editing software.

Repairing a JPG File

JPG Image File Header Data

The data contained within a JPG image file is binary, and it is the first sequence of bytes within the file that contains the header data for the image, which contains information such as image width, height, colour depth, palette, and other metadata.

Knowing how this header data is formed and what the header data should be for each individual file type allows our tool to not only ensure the file is using the correct file extension but also that all the expected pixel data is present and correct.

Lossy / Non-Lossy Compression

Certain image file formats, such as JPG, store their data in a compressed state whereby pixel detail is not identical to the original image. The loss of detail is usually not noticeable and can save a lot of space, leading to much reduced file sizes. An example of a non-lossy format would be the BMP format, which stores pixel data at exactly the same level of detail as the original image. When it comes to validating and repairing an image file, the fact that the format is lossy or non-lossy does not really affect the repaired file. Any repaired file will be in the same format, and our tool will respect the original compression settings.
