WHAT IS A JPEG IMAGE

Advantages, Disadvantages and Recommended Use Cases 

".jpeg"

(pronounced jay-peg) is an acronym for "Joint Photographic Experts Group" and is a raster format based on lossy compression used for digital images, particularly those produced by digital photography, that was made publicly available in the year 1992.


Advantages

  • You have full control over the compression/quality ratio.
  • The small file size makes the JPEG format ideal for web-related content, where images need to be loaded fast without stressing the server or the local machine.
  • Compatibility across all operating systems and web browsers.

Disadvantages

  • The JPEG format doesn't support alpha channels (transparency).
  • Once the image is saved using this format, any quality loss is permanent as long as the original source file has been discarded.
  • The process of resizing or scaling will result in quality degradation.

Recommended Use Case

  • The small file size makes the JPEG format suitable for most use cases, such as websites, visual presentations, or quick project previews that don't require extremely high-res images.
  • While the format is not the highest in terms of quality, it can confidently be used in non-high-resolution printing, such as text documents that are accompanied by images.
  • Due to its intended nature, the JPEG format is best associated with digital photos, but it can also be used to export vector-based images such as illustrations, icons, etc. However, it will come at a higher file size compared to a PNG file.
