The basic path: download, place the mod file, and launch

Adding a mod to Minecraft means downloading a file from a mod site, putting it in your Minecraft folder, and launching the game through a mod launcher instead of the standard launcher. The exact steps depend on which mod loader you use — the most common is Forge, which works with most mods and handles the technical setup for you.

The process takes about 10 to 15 minutes the first time, mostly because you need to download Forge and let it install. After that, adding another mod is usually just downloading the file and dropping it into one folder.

This guide covers Java Edition on Windows, Mac, and Linux. Console versions (PlayStation, Xbox, Nintendo Switch) and Bedrock Edition (the Windows 10/11 version) use a different system called Marketplace and do not support mods the same way.

Key Takeaways

  • You need a mod loader — Forge is the most common — which you download and install once before adding any mods.
  • Mods go into a specific folder on your computer (the .minecraft folder), not into the game itself.
  • Always download mods from trusted sites like CurseForge or Modrinth, not random links, because mod files can contain malware.
  • After you add a mod, launch the game through the Forge launcher, not the standard Minecraft launcher, or the mod will not load.
  • Some mods conflict with each other and will crash the game; start with one or two mods to test before adding more.

Install Forge, the mod loader that most mods need

Forge is software that sits between Minecraft and your mods, translating the mod code so Minecraft understands it. You install Forge once, and then it stays on your computer. After that, you just add mod files to a folder.

Go to files.minecraftforge.net and look for the version of Minecraft you play (for example, 1.20.1). Click the download button next to "Installer". A file called something like "forge-1.20.1-47.2.0-installer.jar" will download to your computer.

Open that file by double-clicking it. A window will appear asking where to install Forge. The default location is fine — just click "Install client" and wait. This takes a minute or two. When it finishes, close the window.

Open the Minecraft launcher (the official one you normally use). You should see a new option in the dropdown menu at the top left that says "forge" or shows a Forge version number. Select it, then click "Play". Minecraft will launch with Forge active. You can close it after it opens — you just needed to confirm Forge installed correctly.

Find and download mods from trusted sources

CurseForge and Modrinth are the two largest mod repositories and the safest places to download. Both are free, require no account to download, and scan files for malware. Avoid downloading mods from random websites, YouTube links, or Discord servers, because those files are not scanned and can contain viruses or malware.

Go to curseforge.com or modrinth.com, search for a mod by name, and look for one that says it supports your Minecraft version. For example, if you play version 1.20.1, the mod page should list 1.20.1 as a supported version. Click the download button. The file will be a .jar or .zip file, usually between 1 MB and 50 MB depending on the mod.

Save the file somewhere you can find it — your Downloads folder is fine. Do not unzip or open it. The mod file stays as-is.

Put the mod file in the mods folder

Minecraft stores all its files in a hidden folder called .minecraft. You need to open this folder and put your mod file inside a subfolder called "mods".

On Windows: Press the Windows key and R at the same time, type %appdata%, and press Enter. A folder will open. Look for a folder called ".minecraft" and double-click it. Inside, you should see a folder called "mods". If you do not see it, create a new folder and name it "mods". Drag your mod file into the mods folder.

On Mac: Open Finder, press Command and Shift and G at the same time, type ~/Library/Application Support/minecraft, and press Enter. You will see the .minecraft folder. Look for the "mods" folder inside it. If it does not exist, create one. Drag your mod file into it.

On Linux: Open your file manager, press Ctrl and H to show hidden files, navigate to ~/.minecraft, and look for the "mods" folder. If it does not exist, create one. Drag your mod file into it.

Launch Minecraft through Forge and test

Open the Minecraft launcher. In the dropdown at the top left, make sure "forge" is selected (not "latest-release" or "latest-snapshot"). Click "Play". Minecraft will load — this takes longer than usual the first time a mod is active, sometimes 30 to 60 seconds.

Once you are in the main menu, look for a mods button or check the bottom left corner of the screen. You should see text that says something like "Mods loaded: 1" or shows the name of your mod. If you see this, the mod loaded correctly.

Create a new world and test the mod. If the game crashes, check the crash log (look in the .minecraft folder for a file called "crash-reports" and open the most recent one). The log usually tells you what went wrong — often a version mismatch or a conflict with another mod.

Add more mods carefully and watch for conflicts

Once you have one mod working, you can add more by repeating the download and folder steps. Download a new mod, put it in the mods folder, and launch Minecraft through Forge again.

However, some mods conflict with each other and will crash the game. Start by adding one or two mods and testing them together. If the game crashes, remove the most recent mod you added and test again. This tells you which mod caused the problem. You can then look up whether those two mods are known to conflict, or try a different mod that does the same thing.

Keep a list of which mods you have installed so you can remove them one at a time if something breaks. Mod files are just sitting in the mods folder — you can delete any one of them and the game will still launch, just without that mod.

Remove a mod or switch mod loaders

To remove a mod, open the mods folder (using the same steps as before), find the mod file, and delete it. Launch Minecraft through Forge again. The mod will no longer load.

If you want to switch to a different mod loader — for example, Fabric is lighter and faster for some players — you install it the same way you installed Forge. However, mods are usually written for one loader or the other, not both. Check the mod page to see which loader it needs before you download.

Frequently Asked Questions

Can I use mods on the Minecraft Launcher without Forge?

No. The standard Minecraft Launcher does not support mods. You must use a mod loader like Forge or Fabric. Some launchers like MultiMC or Prism Launcher can manage mods for you, but you still need a mod loader installed.

Will mods work on Bedrock Edition or console versions?

No. Bedrock Edition and console versions use a different system called Marketplace. You can buy add-ons through Marketplace, but these are not the same as mods and are created by Minecraft partners, not the community.

What if a mod crashes my game?

Delete the mod file from the mods folder and launch Minecraft again. If you have multiple mods, remove them one at a time to find which one is causing the crash. Check the crash log in the crash-reports folder — it usually says which mod failed to load.

Do I need to update mods when Minecraft updates?

Usually yes. When Minecraft releases a new version, mod creators update their mods to work with it. Check the mod page to see if a new version is available for your Minecraft version. If not, the mod may not work until the creator updates it.

Can mods give my computer a virus?

Mods from CurseForge and Modrinth are scanned for malware, so the risk is very low. Mods from unknown websites or random links carry real risk. Stick to the two major sites and you will be safe.
