About UUEncode Encode/Decode

This tool converts text to and from UUEncode format, with header controls, file metadata settings, and basic size statistics for legacy compatibility scenarios.

Core Features

  • Two-way conversion: switch between encode and decode workflows.
  • Header control: include or strip begin/end sections as needed.
  • File metadata: configure output filename and Unix mode bits.
  • Samples and quick reset: built-in samples and clear actions.
  • Stats view: original size, encoded size, and expansion metrics.

How To Use

  1. Choose Encode or Decode tab.
  2. Enter source text or UUEncode payload.
  3. Configure header and file options if needed.
  4. Copy output for transfer, restore, or debugging.

Typical Use Cases

  • Interoperating with legacy mail or Unix pipelines.
  • Recovering archived UU encoded content.
  • Learning and troubleshooting classic encoding formats.

FAQ

Why does decoding fail?

Common causes are truncated lines, malformed payload, or missing begin/end blocks.

How should file mode be set?

Use a 3-digit octal value such as 644 or 755. Non-standard input is sanitized automatically.
