WinRAR is quite capable of reducing large files significantly. It can shrink them to sizes as small as the uncompressed version or even an unzipped state. For instance, a 12GB file might be compressed down to a much smaller size after compression.

Raring a zip offers no advantage. Rar uses the same approach as zip does—it's Run Length Encoding. When you compress a zip (or vice versa), you're just appending extra header data, which only makes it bigger. Text files compress well, while video and audio compress very little. It's smarter to re-encode video and sound at a lower bitrate or quality.

The explanation centers on how compression relies on patterns within data. This is why audio and video struggle to compress effectively—most content is unique. That’s why lossy and lossless formats exist. Lossy methods approximate by assuming similar values are acceptable, reducing file size but potentially lowering quality since subtle differences matter. Lossless approaches preserve every detail, maintaining higher fidelity without significant loss. There’s no quality measure for text, which is why the distinction matters more clearly in visual media.
