UUE is a binary payload smuggled through plain text: uuencode packs every 3 bytes into 4 printable characters so files could survive 7-bit Usenet and email gateways in the 1980s.
Typical use: Decode UUE back to the original binary — a single file or a whole tar.
About the UUE format
uuencode was the 1980 answer to a 7-bit world: three binary bytes packed into four printable ASCII characters, so binaries could ride email and Usenet gateways that would eat anything above 127. The payload sits between `begin 644 name` and `end` lines, quantized to 45-line chunks.
Decoding is pure arithmetic — no wasm, no dependencies — and the payload is often a full tar, which this converter repackages into whatever modern container you want.

- ✓ Self-describing (filename in the begin line)
Limitations
- ✗ 33% size overhead
- ✗ Obsolete for real transport
- ✗ Multiple legacy dialects exist
- Structure
- begin/end lines + 4-for-3 ASCII blocks
- Types / schema
- ASCII armor over binary
- Compatibility
- uudecode, 7-Zip, mailers
- Best for
- Text-gateway binary transport (legacy)
