If you’ve ever downloaded a GameCube or Wii game for use with the Dolphin Emulator, you have likely encountered the file format. Introduced in 2020, RVZ is Dolphin’s smart, lossless compression format designed to save hard drive space while retaining 100% of the game data.
dolphin-tool convert -i "C:\path\to\game.rvz" -o "C:\output\folder" -f iso convert rvz to iso free
The Dolphin Emulator—a tool you likely already have installed—is a complete, professional-grade conversion suite. In less than 60 seconds, you can turn any compressed RVZ back into a raw, universal ISO file ready for modding, burning, or loading on alternative hardware.

Open a terminal (Command Prompt, PowerShell, or Bash) in that directory (or add it to your PATH). In less than 60 seconds, you can turn
for %i in (*.rvz) do dolphin-tool convert -i "%i" -o "Converted_ISOs" -f iso (Note: For Linux/Mac bash, use for i in *.rvz; do instead)
