JPEG Vs JPG: Everything You Need To Know

In this article, we will be comparing JPEG Vs JPG and discussing the various types of image file formats and what they do.

JPEG Vs JPG: Not all image file formats are made equal, some were created to address a problem that an already-existing format could not resolve. In this article, we will be comparing JPEG Vs JPG and discussing the various types of image file formats and what they do.

Let’s look at the types of image formats available.

What Is A JPEG?

Joint Photographic Experts Group(JPEG) was first issued in 1992 by the International Organization for Standardization (ISO).

JPEGs are 24-bit still raster images, with eight bits in each channel of the RGB color model, Although, it can support over 16 million colors but does not support transparency. 

JPEG compression is based on a lossy image compression technique known as the discrete cosine transform (DCT), which was first designated by electrical engineer Nasir Ahmed in 1972.

What Is A JIF (Image File Format)?

This JIF file is similar to JPEG in its “purest” form. Although the format isn’t used much anymore because of its limitations.

JPEG/JFIF is the most popular format for storing and transmitting photographic images on the internet.

While JPEG/Exif is that for digital cameras and other image capture devices.

What Is A JPG2 or JPF?

This when created was meant to be a successor to the JPEG, but was nowhere near as popular. 

The JPEG 2000 file format went wrong because it was based on an entirely new code and thus wasn’t backward compatible with the JPEG. 

Handling JPEG 2000 files required more memory to process, which was a bit of a deal-breaker back then. 


Early versions of Windows had a maximum 3-letter limit when it came to the length of file extensions, for instance, JPEG had to be shortened to JPG as to not exceed the limit. 

While Linux and Mac never had a problem with the format and will continue to save its image in JPEG format.

And that’s how we ended up with two file extensions for the same format: JPEG and JPG. It all depends on what you want to save your image with.

JPEG vs. PNG (Image File Format) Which Is Better?

JPEGs are better for photographs because they utilize lossy compression to keep to reasonable file sizes. 

Photographs are big, detailed images that compression artifacts aren’t extremely noticeable.

Images with sharp points, crisp edges, and with large areas of one color (e.g. Logo.) don’t look quite right when saved as a JPEG.

And This is where to use the  PNG format. PNG was Developed by the PNG Development Group four years after the release of the JPEG.

It supports lossless data compression, transparency and often used if image quality must be retained and file size is not an issue.

Important notice: Note that JPEG and JPG Are the Same File Format, one is being used on the early versions of Windows due to its limitations while The other one is being used in devices such as Linux, Mac, etc.
