Understanding ARW and PCX Formats

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

Source Format

Sony Raw Image

image/x-sony-arw

ARW (Alpha Raw) is Sony's proprietary raw image format used by Sony Alpha mirrorless and DSLR cameras. Based on the TIFF specification, it stores unprocessed 12-bit or 14-bit sensor data with complete metadata. ARW files can be either uncompressed or use Sony's lossy or lossless compressed raw encoding.

Advantages

  • Preserves full unprocessed sensor data for maximum post-processing latitude
  • Supports both compressed and uncompressed raw storage options
  • Well-supported by major photo editing applications including Lightroom and Capture One

Limitations

  • Proprietary format with no publicly available specification
  • Large file sizes, especially in uncompressed mode
  • Requires raw-capable software for viewing and editing

Common Uses

  • Professional photography with Sony Alpha series cameras
  • Raw photo editing and non-destructive development
  • High-quality archival of photographic captures

Target Format

PCX Image

image/x-pcx

PCX (PiCture eXchange) is one of the earliest widely used bitmap image formats, originally developed by ZSoft Corporation for its PC Paintbrush program in the 1980s. It uses a simple run-length encoding (RLE) compression scheme and supports color depths from 1-bit to 24-bit. PCX was once the dominant bitmap format on DOS and early Windows platforms but has been largely superseded by PNG and JPEG.

Advantages

  • Simple RLE compression is fast to encode and decode
  • Lossless compression preserves image quality
  • Widely supported by legacy imaging software

Limitations

  • Largely obsolete, replaced by modern formats like PNG
  • RLE compression is inefficient for complex photographic images
  • Limited to 24-bit color with no alpha transparency support

Common Uses

  • Legacy application compatibility and file conversion
  • Historical document archival from older systems
  • Retro computing and DOS-era software
