Convert MRPack files without guessing what is inside

A good MRPack to ZIP workflow should do more than rename a file. It should read the Modrinth manifest, show the pack details, copy overrides, and explain which remote mod files could not be downloaded by the browser.

What is an MRPack file?

An .mrpack file is the Modrinth modpack format for Minecraft. It is a ZIP-based archive that includes modrinth.index.json, pack metadata, dependency versions, optional overrides, and download links for the actual mod files. Because many mods are referenced by URL, an MRPack is often a manifest rather than a complete folder of JAR files.

Why convert MRPack to ZIP?

Some launchers, hosting panels, and manual server workflows are easier to manage with a normal ZIP layout. Converting an MRPack to ZIP can help you inspect the pack, move config overrides, prepare a server upload, or share a more familiar folder structure with another player.

Why can downloads fail?

Browser-based conversion is private and simple, but remote hosts can block direct downloads with CORS rules. When that happens, this tool records the missing file path, download URL, environment flags, and hashes in a failed downloads report so you can complete the pack manually.

Why this tool exists

A Modrinth .mrpack file is a compact manifest. It usually contains metadata, overrides, and download URLs for the actual mod JAR files. This tool reads the manifest, fetches the referenced files when your browser allows it, and builds a normal ZIP layout.

MRPack Converter FAQ

Is my modpack uploaded to a server?

No. Local files are read in your browser. Remote mod files are fetched directly from their listed URLs.

Why do some mods fail to download?

Some file hosts block browser downloads with CORS rules. The log shows failed files so you can add them manually.

Does this work with CurseForge?

The output is a standard ZIP folder structure. Compatibility depends on the target launcher and the mods referenced by the pack.

Can I inspect an MRPack without converting it?

Yes. Upload the file and use Inspect only to view the Minecraft version, loader, file count, environment flags, and overrides.
