JPG vs. JPEG: What Is the Difference Between These Image File Formats?
Are JPGs and JPEGs the same? Or something completely different?
The JPEG is a great example of how an image file can be created to address problems with other formats. The original idea for this was to make more efficient use of storage space, but it turned into something much bigger than expected!
Believe it or not, the JIF, JPEG, and JPG file extensions more or less refer to the same thing. The file format has many names, and it’s important to understand why.
What Is a JPEG?
JPEG is an acronym for Joint Photographic Experts Group—the file type was named after the sub-committee that helped create this standard. It came out in 1992, and it’s been around ever since with few changes made until recently when ISO decided they needed some new features added into their standards defining what makes up a good image quality-wise.
JPEGs are 24-bit still raster images with eight bits in each channel of the RGB color model. This leaves no room for an alpha channel, which means that while JPEG can support over 16 million colors they cannot support transparency at all!
JPEG is a widely used compression format for storing images. When an image gets saved as JPEG, some data from it gets discarded in the process called lossy file compression which reduces its size by 50% while still maintaining most of its quality; this means you can take up less storage space with little perceptible impact on your photo’s appearance!
JPEG compression is a type of technology that can reduce the file size and quality, while still maintaining image integrity. JPEGs use an algorithm called “discrete cosine transform” or DCT for short which was first proposed by electrical engineer Nasir Ahmed in 1972 to achieve this goal.
What Is a JIF?
You can think of a JIF file is as a JPEG in its “purest” form. However, It’s not used much anymore because it has some frustrating limitations like the color and pixel aspect definitions that caused compatibility problems between encoders/decoders (viewers).
Thankfully, these problems were later addressed by other “supplementary” standards that built upon the JIF. The first of these supplementary standards was the JPEG File Interchange Format (JFIF), which later became known as Exif and ICC color profiles.
JPEGs are the most popular format for storing and transmitting photographic images on internet while JFIFs are used in digital cameras. Most people don’t distinguish between these variations, referring both formats simply as JPEG.
What Is a JPG2 or JPF?
In 2000, the JPEG group released an updated image file format called JPEG2000. It was meant as a successor to popularize over its predecessor but failed due in part. Even when its advanced encoding method often led to better quality images.
The JPEG 2000 file format flopped for a small handful of reasons. JPEG 2000 was an ambitious new file format that tried to incorporate all the features of old school JPEGs with more advanced technology. However, it wasn’t backwards compatible and required additional memory for processing–which didn’t exist in most computers back then!
JPEG 2000 has seen some success as a file format on the internet. Computer hardware improved over 22 years, but JPEG2000 still isn’t widely used because of limited browser support at this time – only Safari offers access to these files for download or upload onto websites today!
JPEG vs. JPG
When Windows began to use a new file system in MS-DOS 8.3, it came with an unfortunate side effect -had a maximum 3-letter limit when it came to the length of file extensions. JPEG had to be shortened to JPG as to not exceed the limit. Mac and Linux computers never had such a thing, and so users would continue to save images as JPEG.
In an effort to minimize confusion, popular image editing programs would eventually set their default JPEG file extension from JPG on any operating system.
The difference between JPEG and JPG is only the file extension, so when choosing what to save your image as there’s no need for confusion.
JPEG vs. PNG:Â Which Is Better?
JPEG and PNG are constantly compared to one another, even in modern times. The reason for this? JPEG was released back when digital images were first taken off as a technology; it resolved all of the problems faced by photographers who wanted better quality than GIF or JPG files could provide them with (like less compression). On top of solving these issues early on though – before anyone else had even thought about implementing such things- JPEG also provided ways so you could easily compress your photos without losing any information while doing so! This made sure everyone was able.
The JPEG and the PNG were released within the same decade, with each file format resolving a different digital image problem that the technology world faced back then. You could say that it’s only natural that they are constantly compared… and they are, even to this day. Between JPEG and PNG, which image file format reigns supreme?
The answer to this question will vary depending on the kind of image you’re saving.
JPEGs are the best choice for photographs because they utilize lossy compression to keep file sizes reasonable. The subtle image distortions caused by this process don’t show up on larger, simpler pictures like those in a magazine or book illustrations – which means you can save lots of space without sacrificing any detail!
On the one hand, images with sharp points or post edges don’t look quite right when saved as a JPEG. On top of that pixel art is another type of image that doesn’t work well for this format either due to its lack of detail and quality.
The Portable Network Graphics (PNG) file is a popular graphics compression standard that supports lossless data compression and transparency. PNG files are thus often used if image quality must be retained while not compromising on size, as seen with JPEG images.
JPEGs are best for photographs, while PNG files can store any type of image with transparency and non-photographic elements.
JPEG and JPG Are the Same File Format
The JPEG has caused much confusion with its many updates and variations, but it was the release of digital images on the internet in the mid-90s that really kicked off this trend. It was a game-changer in the 90s when it replaced old technologies like VCRs and floppy disks for digital media.
When you’re ready to export a photo from an image editor, just remember that the long list of available formats is only going one way. From JPG and JPEG, both being the exactly the same thing as each other but with different capitalizations for some reason–it’s easy enough not to worry about this anymore since they mean essentially identical things!
