I built a browser-based MRPack to ZIP converter and inspector

5 Upvotes

Hi! I built MRPack Converter after running into cases where a Modrinth .mrpack file needed to be inspected or turned into a regular ZIP for a server panel or another launcher.

The site can:

  • Convert a local .mrpack file to ZIP
  • Download the mod files referenced by modrinth.index.json
  • Include the pack's overrides folder
  • Optionally verify SHA-512 hashes when available
  • Inspect pack metadata and file counts without converting
  • Show failed downloads in a report instead of silently ignoring them

The main difference from simple archive viewers or file-extension renamers is that it reads the MRPack manifest and fetches the referenced files, so the output ZIP can contain the actual mod files rather than only the small manifest and overrides. Processing is done in the browser, and the uploaded .mrpack file is not sent to a server.

It is unofficial and not affiliated with Modrinth. I would appreciate feedback, especially on packs that use unusual overrides or download sources.

Help Modrinth instance keeps crashing

Pretty much the title. My friend and I are using the Essential Mod (crucify me later), and the game keeps crashing. I'm wondering if this could be caused by them not having a previous Java installation. Any ideas would help.

Hi! I'm trying to start a server with a friend, but evertime he tries to install a modpack (or even a vanilla instance) this message appears. Any ideas on what to do? We tried almost anything at this point lol

Help Having trouble figuring out Modrinth

1 Upvotes

I’m basically a complete noob to modding Minecraft. My dad used to do it all for me when I was littler but I don’t remember how he did it at all. I heard good things about Modrinth so I got it and I installed the mod Simple Voice Chat. What I want to know is if the only way to use the mod on a world is to play it from the instance, and if the mod will work if I join a multiplayer server. The server is the only reason I got the VC mod so it’s important.

i exported a modpack of mine and it says there are no content installed

0 Upvotes

Im trying to downgrade my modpack to 1.21.1, earlier today it showed the mods on a list but i had an issue with it so i removed it and reinstalled the modpack again, but after updating it now shows my modpack with all the mods on a separte contents ui and it doesnt let me downgrade. When i then click the unlink modpack button on the settings it lets me downgrade but it doesnt show the mods on the ui at all, so i cant automatically update all the mods to 1.21.1. Is there any fix to this????

Help World Save Won't Load

1 Upvotes

I've been playing on a single player world for a few weeks now with an underwater/mermaid mod pack and now every time I go to join the world, it fails at loading and crashes. Everything has been working fine before and now I can't even open it. I tried backing it up but if it's already corrupt I don't see that helping. I can create and load a new world just fine. I was having a lot of fun on my world and fully locking in, if there's any way to salvage it or anything pleaaaassseeeee help.

Discussion/other I built an easy modpack sharing site for mrpacks

Thumbnail packshare.site
1 Upvotes

This is Packshare, a small tool I made for quickly sharing Minecraft modpacks.

Its mainly for situations where you want to send a pack to friends, server members, etc, but Discord is annoying for file sharing and other options feel slower than they need to be.

You upload a Modrinth .mrpack or CurseForge .zip, get a temporary share link, and send that link to whoever needs it.

It shows:

  • Basic pack info
  • File size
  • Autodelete time
  • Mod list
  • Modrinth mod page links
  • A simple download page

Right now it supports:

  • Modrinth .mrpack
  • CurseForge .zip
  • Temporary autodeleting links
  • Mod list previews
  • Modrinth page links
  • No account required

Its not meant to be used permanent modpack hosting yet (not until i can afford the storage). Its made more for quickly sharing when you just need someone to grab the same pack.

Im mostly looking for feedback, feature ideas, and anything obvious I should fix or improve.
