What is a JPG file?

A JPG file is a graphic file which is composed of a large collection of square pixels.

In the image above, the eyebrow of the male is extremely magnified. Then you can clearly see the square pixels. So unfortunately a jpg file cannot be magnified without loss of quality.

Difference between JPG and JPEG

You may not have a jpg file but jpeg. You’re probably wondering if that letter “e” makes a difference? The simple answer is no. Both files have the same quality.

The reason for the difference in file formats goes back to the first versions of Windows. The original file format of the Joint Photographic Expert Group was “jpeg. But because Windows could only work with file formats that had a maximum of three letters, the extension was shortened to ‘jpg’.

Apple computers could work with a longer file extension. Eventually, Windows also accepted files with a longer name. But because everyone was used to ‘jpg’ by now, it is still the most widely used file format today.
