Updated on November 21, 2018

When dealing with images online and photographs you have probably seen both the JPG and JPEG extensions floating around. Sometimes this tin exist confusing for people as they don't know which extension they should be using. Today we desire to speedily explain the difference between JPG and JPEG, or if in that location is one, and what y'all should be using for your online projects.

Difference between JPG and JPEG

JPEG

JPEG is a file extension that stands for Joint Photographic Experts Grouping. The ISO standard was originally released dorsum in 1992. It is a bitmap pinch format, most unremarkably used for lossy compression, with compression ratios ranging from x:1 to 20:i. The compression ratio can be adjusted which means you can determine your own balance between storage size and quality. The JPEG extension is about commonly used by digital cameras and photo sharing devices.

While the JPEG format is great for colour and photographs, information technology is besides important to note that there is a slight loss of quality due to compression. And editing and re-saving simply degrades the quality, even though it might be negligible. Ane way to minimize this is to work with the RAW JPEGs, determine your edits, then relieve out the last version without re-saving multiple times.

The MIME media type for JPEG is prototype/jpeg (defined in RFC 1341), except in older Net Explorer versions, which provides a MIME type of image/pjpeg when uploading JPEG images. JPEG is likewise defined with the additional extensions, .jpe, .jif, .jfif, and .jfi.

JPG

Then nosotros have the JPG format. There are actually no differences between the JPG and JPEG formats. The only departure is the number of characters used. JPG merely exists because in earlier versions of Windows (MS-DOS 8.iii and Fatty-16 file systems) they required a iii letter of the alphabet extension for the file names. So .jpeg was shortened to .jpg. While Windows and or DOS had this limitation, UNIX did non and so UNIX and MAC users continued to use the .jpeg extension. Newer versions of Windows of course now accept more characters in their file extension, all the same, .jpg was already being used by a bulk of people (and programs needed to piece of work with MS-DOS 8.3) and so information technology nevertheless is the most mutual extension.

Photo editing programs like Adobe Photoshop and Gimp, all salve JPEGs by default to the .jpg extension, on both Windows and MACs. And if you were wondering, y'all can change the extension both ways and the file will continue to piece of work.

Summary

As you can see, when information technology comes to the difference between JPG and JPEG, there is none. JPG was simply born out of a limitation that existed by previous versions of Windows and or DOS, and now is really the most common format, over that of JPEG.
