UUE vs XAR: Key Differences

•The core technical difference: UUE relies on lossless compression whereas XAR uses lossless compression.
•Neither format changes compression philosophy — both are lossless compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
•How transparency is handled: XAR supports transparency, so alpha information is preserved during conversion.
•File sizes: UUE files typically range 33% larger than original and XAR files N/A.
•UUE is optimized for usenet file sharing, legacy email attachments while XAR is designed for macos package installers, browser extension packaging — choose based on your specific workflow needs
