However, compression level affects compatibility, decompression speed, and save state functionality.
: You cannot play a compressed archive (like .rar or .7z ) directly. You must extract it back into a standard format ( .iso ) or convert it to a compressed format that emulators natively support ( .chd or .cso ). The Best Formats for Compressed PS2 Games
Compressing PS2 ISO files is essential to reduce their massive size, making them easier to store and transfer. A typical uncompressed PS2 ISO file can range from 4-9 GB in size, which can be a significant burden on storage devices and internet connections. ps2 iso files highly compressed full
Instead of risking malware by downloading pre-compressed files from sketchy, ad-ridden websites, the safest and most efficient method is to download the official full ISOs from trusted archival sites and compress them yourself. It takes only a few seconds per game.
Avoid lossy methods unless you are willing to risk broken FMVs or audio.

Standard compression formats (like .zip or .rar) work by removing redundant data. While they can shrink a PS2 ISO, the results are rarely drastic.
means the file has been processed using algorithms (like LZMA) to shrink its size significantly without altering the core content.
Blank data used by developers to fill up the physical space on a DVD. This positioned the actual data on the outer edges of the disc, making it read faster on physical PS2 hardware.
