When Should You Use NRG vs CAB?

NRG vs CAB: Key Differences

• •The core technical difference: NRG relies on lossless compression whereas CAB uses lossy compression.
• •Moving from NRG (lossy) to CAB (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
• •How transparency is handled: CAB does not support alpha channels — transparent areas in the source will become opaque.
• •File sizes: NRG files typically range 700MB (CD) to 50GB (Blu-ray) and CAB files Comparable to ZIP.
• •NRG is optimized for cd/dvd burning, disc imaging, backups while CAB is designed for windows software installation, drivers — choose based on your specific workflow needs
