What is an .mrpack file?

A quick primer on Modrinth's modpack format and why you might want a plain .zip instead.

The .mrpack format

An .mrpack is a ZIP archive containing a modrinth.index.json manifest that lists every mod by download link, plus an overrides/ folder of config files — it doesn't bundle the mod JARs directly, which keeps the file small.

Why convert to .zip?

Many launchers and manual installs expect a plain .zip with the mods already inside. Converting bundles every mod into one self-contained archive, so the pack installs anywhere and works offline after download.

How it works

Turn a Modrinth modpack into a ready-to-use ZIP in a few simple steps.

1

Find a modpack

Find the modpack project you want on Modrinth.
2

Provide it

Copy the project ID or download link, or upload a local .mrpack file.
3

Convert

Click convert and wait for the mods to download and package.
4

Download

Get a ready-to-use .zip file automatically.

Tip: Some mods hosted on sites like GitHub can't be downloaded automatically because of browser CORS restrictions. The converter opens their download pages for you — just drop them into the ZIP's mods folder manually.

Frequently Asked Questions

Everything you might want to know before converting your first modpack.

What is mrpack2zip?

It's a free, browser-based tool that converts Modrinth .mrpack modpacks into plain, ready-to-use .zip archives — no account or installation required.

Are my files uploaded to a server?

No. The entire conversion runs locally in your browser. Your modpack never leaves your device; the only network requests are to the public CDNs that host the mods themselves.

Is it free to use?

Yes, completely free. There are no accounts, limits, or hidden fees.

Why would I convert .mrpack to .zip?

Some launchers and manual setups can't read .mrpack and expect a plain .zip with the mods already inside. A converted ZIP installs anywhere and works offline after you download it.

Some mods didn't download automatically — why?

A few mods are hosted on sites like GitHub that block in-browser downloads due to CORS. The converter opens their download pages for you; just add those files to the ZIP's mods folder manually.

Which inputs are supported?

You can convert by Modrinth project ID, a direct .mrpack download link, or by uploading a local .mrpack file.
