8 Difference Between Joint Photographic Experts Group (JPEG) And Portable Network Graphics (PNG)

Joint Photographic Experts Group (JPEG)

JPEG is an acronym for ‘’ Joint Photographic Experts Group”. It’s a standard image format for containing lossy and compressed image data. Despite the huge reduction in file size JPEG images maintain reasonable image quality. This unique compression feature allows JPEG files to be used widely on the internet, computers and mobile devices. The sharing of JPEG images is quick and efficient. Also, a large number of JPEG files can be stored in minimum storage space. JPEG files can also contain high-quality image with a lossless compression. In PaintShop Pro JPEG is a commonly used format for storing the edited images.

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

What You Need To Know About Joint Photographic Experts Group (JPEG)

  • It uses lossy compression algorithm.
  • JPEG images are used in photography.
  • JPEG images use .jpeg or .jpg extension.
  • JPEG does not support transparency in images.
  • JPEG image is generally smaller than PNG image of same image.
  • JPEG image may lose some image causing quality loss.

Portable Network Graphics (PNG)

Portable Network Graphics is a raster-graphics file-format that supports lossless data compression, meaning all image information is restored when the file is decompressed during viewing. PNG was developed as an improved, non-patented replacement for Graphics Interchange Format (GIF). PNG supports palette-based images, grayscale images and full-color non-paletted-based RGB or RGBA images.

The PNG file image format is one of the most popular contributors to the abundant number of images we see today on the internet. It was designed for transferring images on the internet, not for professional-quality print graphics and therefore does not support non-RGB color space such as CMYK. PNG files nearly always use file extension PNG or png and are assigned MIME media type image/png.

PNG supports 24 bits per pixel, so that a single image could reference over 16 million colors, as compared to the palette of 256 distinct colors supported by the GIF format. In addition to the visual color representation of information they also contain plain text details such as image author name and description.

What You Need To Know About Portable Network Graphics

  • It uses lossless compression algorithm.
  • PNG images are generally used in icon creation.
  • PNG images use .png extension.
  • PNG supports transparency in images
  • PNG image is generally larger than JPEG image of same image.
  • PNG image is of high quality.
