JPEG VS JPG: Are They Different Or Same?


JPEG vs JPG! If you had also worked with digital graphics when you only downloaded a few images from the internet, you should know that there is a vast compilation of formats.

Two of them look almost identical, and all of them are JPEG and JPG.

At first glance, these format options almost look the same.

JPEG and JPG are so similar that you may have used the two terms interchangeably in the past.

What is JPG?

JPEG vs JPG, the only significant difference is the variety of characters used. JPG is still because previous versions of Windows / DOS systems required a 3-letter extension for document names.

Therefore .jpeg was shortened to .jpg. Windows currently support the four-letter extension. Hence, you can open JPEG files on Windows.

Mac and Unix operating systems did not have this character limit. They continued to use the JPEG format.

Your photo editing software, including Adobe Photoshop, Gimp, will restore JPEG files with a .jpg extension. You are free to change the file extension methods, and the document will still work.

Unlike JPEG, JPG retains the image quality of this document with less data redundancy after compression.

Therefore, JPG files take up more space. Since JPG files also use lossy compression algorithms, the image quality contrasts with the decrease in file size.

What is JPEG?

The Joint Photographic Experts Group (JPEG), along with other cameras, is one of the most common image formats used by digital cameras.

It is also widely used in stores and for sharing photos online. JPEG files have a .jpg or .jpeg extension.

JPEG is a bitmap compression structure that is very popular for lossy compression, even at compression ratios of 10: 1 to 20: 1.

This compression ratio can also be changed so that you can correct the balance between storage quality and size.

Just as ZIP files use excess files to achieve compression, JPEG can remove blocks of pixels or image segments, reducing the overall image quality.

Saving and editing the graphic multiple times also simplifies the image quality. A workaround is to use RAW JPEG files, understand all of your edits, and then save the final output without saving your document multiple times.

Due to compression, JPEG files only take up a few megabytes of storage space. Due to their small size, websites use JPEG images on their pages.

Why are JPEG and JPG named differently?

If the names JPEG and JPG are virtually interchangeable, why is there a difference? The spelling difference is related to the way some programs or operating systems handle file extensions.

What is a file extension? A file extension is a form of metadata that tells a computing device how to store information in a file. The extension also describes the type of data stored, shared, or modified.

Difference between JPG vs. JPEG

JPG and JPEG operating system: –

Other models of operating systems such as MS-DOS and Windows can only read three-letter extensions to obtain image file formats. Therefore, the Joint Photographic Experts Group has contradicted the word “E” in JPEG to use JPG.

However, there are no such restrictions for Macintosh. As a result, JPEG is only a popular file format for Mac users.

Image Applications: JPEG vs JPG

Most image processing and editing programs such as Microsoft Paint and Adobe Photoshop use the “.jpg” extension to retrieve all JPEG image files for Mac and Windows users.

Both document formats are best for photography with all the flawless changes in colours and tones like paintings.

Number of characters

JPG and JPEG have often been used the same way because they are almost identical and created by the Joint Photographic Experts Group.

The significant change among the two, however, is the character space used in each file extension. The two are just different small file extensions used by an organization with JPEG processing.

File Size of JPG and JPEG

The size of these JPEG extension image files is relatively smaller due to the lossy compression algorithm that results in severe data loss.

On the contrary, JPG uses this compression method optimally to save image quality with less information redundancy.

JPEG vs. JPG Examples

Publish your scanned images from the scanner and save a JPG file.

Correct size, conversion, and get expandable JPG functionality.

JPEG can shrink files to 5% of their original size.

Users can cut out exactly what they want and save it in a JPG prepared for use on the website.

Sam provided me with a JPEG of his family with Christmas dinner, but I can’t open it.

The photo was saved as a document in JPEG format.

JPEG and JPG alternatives

There are various extensions for camera RAW files. Some manufacturers may also use a generic. DNG RAW file extension. There can even be different RAW extensions within a single camera brand, e.g., Eg B.crw, .cr2, and .cr3 within the Canon trademark.

Many of these RAW extensions require a program that can read the RAW file. There are also converter programs that can change the proprietary RAW file to something else, sometimes the .dng file, sometimes a different alternative.

TIFF (.tif) is an excellent alternative to RAW or JPEG cameras. TIFFs are a great format because they are lossless and uncompressed. Although JPEGs are easy to use and broadly compatible, they are compressed format that has certain limitations.

Other file formats displayed are .PNG, .GIF, .PDF, .PSD, and .EPS. There are good reasons to use them.
