Decoder

• 
  
• written in C99
  
• can parse YCbCr, YCCK and grayscale images
  
• can handle 8-bit or 12-bit samples
  
• can handle subsampled components
  
• can handle restart markers
  
• supports interleaved and non-interleaved scans
  
• supports Motion JPEG
  
• does not support progressive JPEG files
  
• does not support arithmetic coding
  

Encoder

• 
  
• written in C99
  
• supports subsampled components (4:4:4, 4:2:2, 4:2:0)
  
• uses interleaved scan
  
• supports quality setting (1..100)
  
• support color and grayscale images
  
• uses default Huffman table or optimized tables
  
• can handle 8-bit and 12-bit input images
