What is UUE?

UUEncode (UUE) is a Unix binary-to-text encoding format used for transferring binary files via email and Usenet.

What is PKG?

macOS Installer Package, Apple Flat-Package software distribution archive — stored as application/x-pkg — uses lossy encoding to handle macos software installation, package extraction, application repackaging. Typical file sizes: varies by content.

When Should You Use UUE vs PKG?

Use UUE When...

Reach for UUE when your priority is usenet file sharing, legacy email attachments — its uncompromising quality ensures every detail is preserved.

Use PKG When...
