What is an RLE file?
An RLE file is a Run-Length Encoded image file — a simple compressed raster format where sequences of identical pixels are stored as a count + value pair (e.g., “5 red pixels” → 5 R). RLE is not a single standard format, but a compression method used in several image formats, most notably:

  • Windows Bitmap (BMP) — for 4-bit and 8-bit paletted images
  • Utah RLE — an early Unix scientific imaging format (.rle extension)
  • Some legacy CAD and medical imaging systems
 

What is an RLE file used for?

  • Lossless compression of images with large uniform areas (e.g., diagrams, icons)
  • Legacy Windows BMP optimization
  • Early scientific/medical image storage (Utah RLE)
  • Low-overhead compression in embedded or real-time systems
 

How to open an RLE file?
Depends on type:

  • BMP with RLE compression: Open in any image viewer (Windows Photos, GIMP, IrfanView)
  • Utah RLE (.rle): Use rle tools (from Utah Raster Toolkit), ImageMagick, or GIMP (limited)
  • Generic RLE data: Requires knowing structure — often custom parsers
 

Is an RLE file an image file?
Yes — but only when used as part of a defined image format (e.g., RLE-BMP or Utah RLE). Standalone .rle files are rare and usually tied to specific software.
