Difference between the image formats JPG and JPEG
- JPEG stands for "Joint Photographic Experts Group" and is just as PNG is a standard which defines how an image is compressed. However, there are several sub-types of the format, such as JPG, JPEG, JPE and JFIF. These specify further values which are not determined by the standard, such as, for example, the respective color space.
- Under earlier versions of Windows JPG was used mainly as an abbreviation for JPEG. Windows had often problems to open images with the extension JPEG, as the System could originally only handle file extensions with three characters.
- For the same reason, the identical formats TIF, and TIFF, MPG and MPEG, as well as HTM and HTML still exist today.
- Conclusion: this is a JPG, both the short file extension to JPEG and thus a Remnant from the old DOS-times, as well as a sub-format of JPEG.
