Run-Length Encoding Tool

Compress repeated patterns with RLE and inspect encoded runs.

Input

Compress repeated characters with run-length encoding or expand an encoded run string back into text.

  • RLE works best on input with obvious repeated sequences.
  • Encode mode returns basic size reduction stats.
  • Decode mode expects a compact run string such as 4A3B2C.
