- An ISO/ITU standard for compressing still images
- File extensions are .JPEG, .JFIF, .JPG, OR .JPE

- Best for compressing photographic images (compared to GIFs).
- Mostly used for storing and transmitting photographs on the World Wide Web
Advantages of JPEG:
- low complexity
- memory efficient
- reasonable coding efficiency
- currently applicable for most applications
- can be saved on a sliding resolution scale based on the quality desired
Disadvantages of JPEG:
- not great for text - the text appears fuzzy, especially at low resolutions
- lossy - some data or quality is lost when the image is compressed
What is JPEG 2000?
- New format of JPEG formalised in December 2000.
- File extensions : .jp2, .jpx, .jpf, .mj2

- Uses Discrete Wavelet Transform (DWT)
- Scalable coding of continuous tone still images (from lossy to lossless).
- Provides both lossless and lossy compression in a single compression architecture
Advantages of JPEG 2000:
- Better image quality at the same file size
- 25%–35% smaller file sizes at comparable image quality.
- Good image quality even at very high compression ratios, over 80:1.
- Lossless compression mode (identical to original image).
