Emulators like RPCS3 read data from your hard drive. Smaller files mean faster loading times and less strain on your storage system. Over 70% of PS3 games are now playable on RPCS3, many at 4K resolution and 60 FPS. Using compressed ISOs can further improve emulation smoothness.
For power users, the chdman utility (from MAME) can compress PS3 ISOs into the CHD format, commonly used for PS1 and PS2 games. However, be sure to test compatibility with your emulator or console first. Another option is using , specifying the --ultra -22 flags for maximum compression, though this is very slow.

A command-line tool preferred by advanced users for creating clean, 100% compatible PS3 ISOs directly from game dumps.
Compression works by removing duplicate data (dummy files, unused audio tracks, padding) and applying efficient codecs. For PS3, the system’s own .psarc format supports up to nine compression levels, with level 9 being the default for maximum compression. Highly compressed releases often go beyond this by stripping redundant content and repacking with stronger tools. ps3 iso games highly compressed best
The search for "RPCS3 compatible highly compressed PS3 games" yielded results about RPCS3 compatibility, including a forum thread mentioning games like Uncharted, Killzone, Resistance, and LittleBigPlanet. This could be useful for compiling a list of popular, playable games. The search results are in various languages.
This advanced method involves using a tool that scans the ISO file, identifies the areas filled with dummy data (like large blocks of zeros), and essentially tells the emulator to ignore them. Scrubbing doesn't shrink the file size initially, but it makes the file significantly more compressible when archived with a tool like 7-Zip, because it replaces all that padded data with a simple reference that it can be expanded.
