What is JPEG?

JPEG is Joint Photographic Experts Group. JPEG is a type of image file that is commonly used on the internet. JPEG files are small in size and have a good quality, making them ideal for use on websites. JPEG is a type of image file that is commonly used for email marketing. JPEG files are smaller in size than other types of image files, making them ideal for email attachments. JPEG is a lossy compression algorithm for digital images.

Which are the types of JPEG formats?

  1. Baseline JPEG : Also known as standard JPEG, this is the most common type of JPEG file. Baseline JPEGs are compatible with all web browsers and devices, and can be opened with most image editing software.
  2. Progressive JPEG : A progressive JPEG loads an image in stages, from a low-quality version to a high-quality version. This type of JPEG is useful for large images, or images that will be viewed on a slow internet connection.
  3. Lossless JPEG : A lossless JPEG is an image file that has been compressed without any loss of quality. Lossless JPEGs are useful for images that need to be edited or printed at a high quality, but take up more space than a baseline JPEG.
  4. Grayscale JPEG : A grayscale JPEG is an image that has been converted to black and white. Grayscale JPEGs take up less space than color JPEGs, and can be opened with most image editing software

Importance of JPEG

JPEG is a lossy compression method, that simply means some of the image data is lost when the file is compressed. This loss of data can result in artifacts, or visible defects, in the image. However, JPEG compression can be very effective in reducing the file size of an image, which can be important when storing or transmitting images.

That provides great flexibility if you want to store a huge amount of photographs in digital format. Majority of the digital cameras and phone cameras have options to select default image file selection as JPEG. So, it provides greater flexibility of sharing and editing the images as and when needed.
