Joint Photographic Experts Group Abbreviation, JPEG is a digital image compression format, and one of the most popular image types displayed on the Internet and used with digital cameras.

The JPEG standard uses a lossy discard to achieve more compression. JPEG is also abbreviated as JPG in the file extension used with JPG compatible computers.

JPEG Meaning

JPEG stands for Joint Photographic Experts Group. It is a standard image format for holding lossy and compressed image data. Despite the significant reduction in file size, JPEG images maintain reasonable image quality.

This unique compression feature allows JPEG files to be widely used on the Internet, computers and mobile devices. Sharing of JPEG images is quick and efficient. Also, a large number of JPEG image files can be stored in minimal storage space. JPEG files can also hold high-quality image data with lossless compression.

What is a JPEG?

JPEG stands for Joint Photographic Experts Group. JPEG is a popular image file format. It is commonly used by digital cameras to store photos as it supports 224 or 16,777,216 colours. The format also supports different levels of compression, making it ideal for web graphics.

The 16 million possible colours in a JPEG image are produced using 8 bits for each colour (Red, Green, and Blue) in RGB space. It provides 28 or 256 values ​​for each of the three colours, allowing for 256 x 256 x 256 or 16,777,216 colours combined.

Three values ​​of 0 (0,0,0) produce pure black, while three values ​​of 255 (255,255,255) produce pure white.

The JPEG compression algorithm can reduce the file size of bitmap (BMP) images by up to ten times with almost no degradation in quality. However, the compression algorithm is lossy, which means that some image quality is lost during the compression process.

For this reason, professional digital photographers often choose to capture images in raw format so that they can edit their photos in the highest quality possible. They usually export images as JPEG (.JPG) when they are shared or published on the web.

In addition to image data, JPEG files may also include metadata that describes the contents of the file. This includes image dimensions, colour space and colour profile information, as well as EXIF ​​data. EXIF data is often “stamped” on the image by a digital camera and can include aperture setting, shutter speed, focal length, flash on/off, ISO number, and dozens of other values.

When was the JPEG created?

The group responsible for the format was formed in 1986. The format was introduced and approved in 1992, so it has been around since the early days of the Internet.

When shouldn’t you use a JPEG?

Most digital cameras automatically save your photos in JPEG format, as do most graphics programs. However, if you are creating a sketch or other graphic that includes text/icon graphics, you may be better off saving it in another file format, such as TIFF, GIF, PNG or RAW.

Because graphics like these usually have a sharp contrast between pixels, which can cause some graininess in the image when saved as a JPEG. This avoids the lossless file format by using the formats listed above.

Which programs open JPEG files?

Most image programs can open JPEG files. The most commonly used is Microsoft Windows Photos, which is the default program that comes preinstalled on Microsoft PCs. You can also open a JPEG file in a graphics program like Adobe Photoshop, but these can be expensive and confusing to use. Most web browsers can also open JPEG files.

How can you identify a JPEG?

This will have a file name extension of .jpg or .jpeg. In other words, if you named a photo landscape, the file will appear on your desktop as landscape.jpeg. JPEGs can also take the file name extensions .jpe and .jfif, although these are less common.

Should I save my image or photo as a JPEG?

It’s up to your needs to decide which type to use when saving an image or photo. If the image you’re saving is a basic image with no gradient and not many colours (e.g., a logo or illustration) and you’re concerned about that file size, I recommend you use GIF. I recommend.

However, if you’re working with a more complex image or photograph, I recommend saving it as a JPEG or PNG.

How big is a jpeg file, in bytes?

The size of a jpeg image file can vary widely. The dimensions and resolution of an image are the two biggest factors in determining its size.

The larger the length and width of an image, the larger the size of the image file. The higher the resolution, the higher the image quality, the larger the image file size.

Today, due to the rise in the quality of digital cameras and image editing software, JPEG files can be tens or hundreds of MB (megabytes) in size. However, it is possible to create very small jpeg image files, often called thumbnails, which can be as small as tens or hundreds of KB (kilobytes).

Disadvantages of the JPEG Format

While the JPEG format is great for storing digital photos, it does have some drawbacks. For example, lossy compression can cause a problem called artefacts, in which parts of the image are clearly blocked out. This usually happens when a high compression setting is used to save the image.

For saving small images and images with lots of text, the GIF format is often a better choice.

Also, JPEG images do not support transparency. Therefore, the JPEG format is a poor choice for saving non-rectangular images, especially if they will be published on web pages with all background colours. The PNG format, which supports transparent pixels, is more ideal for these types of images.
