Want to use the tool now? The canonical conversion tool is the MRPack to ZIP converter on the homepage. This guide explains the steps, limits, and repair checks around that workflow.

Before you start: an MRPack is not simply a ZIP with a different extension. It contains a manifest that points to remote mod files, so renaming the extension does not create a complete, ready-to-use modpack.

Convert MRPack to ZIP in five steps

Choose the MRPack file. Open the MRPack to ZIP converter and drop your .mrpack file into the upload area. The file is read locally and is not uploaded to this website.
Inspect the pack metadata. Use Inspect only, or open the MRPack Inspector, to confirm the Minecraft version, loader, referenced file count, and overrides.
Select the conversion options. Keep remote downloads enabled when you want the converter to retrieve available mod files. Keep overrides enabled to include bundled configuration and resource files.
Convert and download the ZIP. Select Convert to ZIP. Keep the browser tab open while referenced files are downloaded and the output archive is created.
Review failed downloads. If the browser cannot retrieve one or more files, download the report and add the exact missing versions manually before launching the pack.

How to convert a Modrinth pack to ZIP

In most searches, "Modrinth pack to ZIP" means converting the downloaded .mrpack file from a Modrinth modpack into a standard archive layout. Upload the MRPack file, keep referenced downloads and overrides enabled, then review the failed downloads report before using the ZIP in a launcher or server workflow.

If you are starting from a Modrinth project slug or direct Modrinth CDN URL, use the homepage converter inputs to load the pack source first. For safety, direct URL fetching is limited to Modrinth CDN .mrpack URLs.

What is inside an MRPack file?

The Modrinth format stores its main metadata in modrinth.index.json. This file lists the pack name, format version, Minecraft and loader dependencies, target paths, download URLs, hashes, and client or server environment rules. The archive can also include an overrides folder containing configs, resource packs, scripts, and other files that must be copied into the final instance.

Official format reference

The archive structure and manifest fields described here follow the Modrinth MRPack format documentation. See the project methodology for this converter's processing, security, and failure-report rules.

Why can an MRPack conversion have missing mods?

The manifest often references files hosted outside the archive. A browser can download those files only when the source permits cross-origin requests and the URL remains available. Removed versions, expired links, network interruptions, and browser restrictions can therefore leave individual files out of the generated ZIP.

A partial ZIP is not automatically safe to launch. Read the conversion log and use the missing mods guide to complete the expected folder structure.

Where can the converted ZIP be used?

To review the pack folders and configuration files manually.
To prepare Modrinth pack files for a Minecraft server hosting panel.
To move overrides into an existing launcher instance.
To share a familiar archive layout with another player.

Launcher compatibility varies. Some launchers support MRPack directly and do not require conversion. Check the Prism Launcher guide or server panel guide for the appropriate workflow. If you only want to extract the archive, see how to unzip an MRPack file.

MRPack to ZIP questions

Can I rename .mrpack to .zip?

You may be able to open the archive after renaming it, but that does not download the mod files referenced by its manifest. A converter builds a more useful ZIP by retrieving those files when permitted and copying the bundled overrides.

Is online conversion private?

On this site, the uploaded MRPack is processed locally in your browser. Referenced mod files are requested directly from their trusted source and are not uploaded to our server.

Does converting change the Minecraft version?

No. Conversion changes the archive layout, not the required Minecraft version or loader. Install the versions listed in the pack metadata.
