About mrpack → zip

mrpack → zip is an ultra-fast, serverless browser utility designed to convert Modrinth modpack archives (.mrpack) into standard ZIP files. This allows you to extract files, deploy them onto servers, or import them into Minecraft launchers that do not natively support the Modrinth format.

Core Features

Concurrent Downloads

Utilizes 8 parallel streams to fetch mods from the Modrinth CDN in seconds.

100% Private

Runs entirely in your browser. Your files and data are never sent to a server.

Server Ready

Easily convert client packs to server-compatible ZIP folders with all configs intact.

Auto-Retries

Automatically retries failed downloads to ensure successful conversion rates.

Frequently Asked Questions

Does my modpack file get uploaded to a server?

No. This utility is entirely serverless. All parsing, mod fetching, and final archive zipping happen directly inside your web browser. No files are uploaded to our end, ensuring absolute privacy.

How does this tool download files so fast?

Unlike standard downloaders that process files one-by-one, our tool runs 8 download operations in parallel. Combined with zero-overhead storage compression when packaging the final ZIP, conversions take a fraction of the time.

Why do some mods fail to download?

Download failures are usually caused by transient network glitches, rate-limiting on the CDN, or broken download URLs in the modpack index. The app automatically retries failed requests up to 2 times. If a download still fails, it is logged and the converter continues so you don't lose the rest of your pack.

Can I use this to set up a Minecraft Server?

Yes, absolutely! The output ZIP contains a mods directory and any config files/folders in the overrides. You can extract the contents of the generated ZIP directly into your Minecraft server directory.

Are there any limits on modpack size?

The only limit is your browser's available memory. Large modpacks (over 200+ mods) can consume substantial RAM during the zipping process. If your browser crashes or reloads, try closing other tabs or using a browser with higher memory limits.
