About this tool

RVZ to ISO is an online file conversion tool that runs in the browser, used to restore Dolphin emulator RVZ format disc images to standard ISO format.

Purpose RVZ is a modern disc image format created by the Dolphin emulator for GameCube and Wii games. It uses strong compression (usually zstd) to shrink multi-GB images to a very small size while remaining completely lossless. However, RVZ has limited compatibility outside Dolphin and a few modern tools. Many emulators, ROM patching tools, MOD loaders, and hardware workflows cannot recognize RVZ. This tool is designed to convert RVZ online to the more universal ISO format without installing Dolphin, without a command line, and without local multi-GB temporary space.

Main capabilities

  • Lossless restoration: audio, video, or game data is not re-encoded; the restored ISO is byte-identical to the original dump.
  • Supports GameCube and Wii RVZ images.
  • Resumable uploads: RVZ files are split into retryable 16 MB chunks, so brief network failures do not cause the entire upload to restart, supporting files up to 10 GB.
  • Privacy by design: each task uses a private access token, files are not publicly listed, and results expire automatically.
  • Conversion runs in an isolated converter container, using Dolphin's conversion engine to restore the standard disc image.
  • The output ISO is downloaded via a private link that supports resuming, and payment is required only after successful conversion.
  • No Dolphin installation or local extra conversion workspace is required.

How to use

  1. Upload the .rvz file and wait for conversion to complete. The file is split into 16 MB chunks for reliable upload.
  2. Conversion runs on the server side in an isolated container using Dolphin's conversion engine to restore the standard disc image.
  3. After successful conversion, pay and download the ISO via a private link; downloads support resuming.

Platform usage

  • Windows: Upload the .rvz file, wait for conversion to complete, download the ISO via the private link, then open it in Dolphin (Config → Paths, add the game folder) or mount it with a disc image tool. For real Wii hardware, copy the ISO to a drive prepared for a USB loader.
  • macOS: Upload and convert (Dolphin for macOS is not required), download the ISO from the private link, install Dolphin for macOS (Apple chip or Intel) and add the download folder in Settings → Paths. The restored ISO can also be used for patches and MOD tools that cannot read RVZ.
  • Linux: upload and convert, download the ISO, and open it with Dolphin (native package, Flatpak, or AppImage) or any tool that reads standard disc images. For command-line workflows, tools such as wit or chdman can be used to further process the ISO.

Use cases

  • When you need to apply ROM hacks or translation patches that expect a pure ISO.
  • To play the game on other emulators or mobile ports.
  • To load the game onto a real Wii using USB Loader GX or Nintendont.
  • To archive a game collection in the most widely supported format.
  • When any tool in your workflow refuses RVZ, converting to ISO is a universal fallback.

Format notes RVZ, ISO, NKit, and WBFS can all store GameCube or Wii games, but each solves a different problem. Unlike NKit, RVZ never discards data; it only compresses. Once RVZ is restored to ISO, it is byte-identical to the original dump, so when a tool requires a standard disc image, RVZ to ISO is the safest path. After conversion, the ISO will be larger than the RVZ; this is expected, because RVZ removes redundancy and compressible space, and restoration rebuilds the full disc layout.

Limits and pricing

  • The upload size limit is 10 GB.
  • Payment options: a one-time pass or permanent credits. A standard conversion uses 10 credits, and RVZ uses 20 credits. There is no subscription and no automatic renewal.
  • 30 days unlimited: applies to this file and every file afterward, with unlimited conversions for all formats (fair use: 20 per day), a one-time payment, never renews, and can convert RVZ files up to 10 GB.
  • 1 year unlimited: lowest price about $4.08 per month.
  • Permanent credit packs: one-time purchase, credits never expire and remain in your account. About $0.05 per credit or about $0.04 per credit.
  • Specific explanations regarding conversion time, reasons for failure, handling files that are too large, and legality are not yet provided.
