Understanding JPEG and RAW Formats

Learn about the source and target file formats to understand what happens during conversion.

Source Format

JPEG Image

image/jpeg

JPEG is identical to JPG and refers to the same lossy image compression standard developed by the Joint Photographic Experts Group. The .jpeg extension is the full-length version of the file extension, while .jpg originated from the three-character limit of early Windows file systems. Both extensions produce and read the exact same file format.

Advantages

  • Excellent compression ratio for photographic images, resulting in small file sizes
  • Universally supported across virtually all devices, browsers, and software
  • Adjustable quality level allows fine control over the size-quality tradeoff

Limitations

  • Lossy compression degrades image quality with each re-save
  • Does not support transparency (alpha channel)
  • Poor choice for images with sharp edges, text, or flat colors due to compression artifacts

Common Uses

  • Digital photography and camera output
  • Web images and social media sharing
  • Email attachments and document embedding

Target Format

Raw Image Data

application/octet-stream

RAW is a general term for unprocessed image data files captured directly from a camera's image sensor, though the .raw extension itself is sometimes used as a generic raw container. Different camera manufacturers use various proprietary raw formats, but files labeled .raw contain minimally processed sensor data preserving maximum detail and dynamic range. These files require specialized software to develop into viewable images.

Advantages

  • Contains the maximum possible image data from the camera sensor
  • Provides full control over white balance, exposure, and color in post-processing
  • Much higher dynamic range than processed JPEG output

Limitations

  • Generic .raw extension can cause compatibility issues with software detection
  • Very large file sizes compared to processed image formats
  • Cannot be displayed directly without raw processing software

Common Uses

  • Generic raw image capture from various camera systems
  • Raw image data from scientific and industrial imaging sensors
  • Intermediate data storage in image processing workflows
