What Forge is and why you need it
Forge is a mod loader — the software that lets Minecraft read and run mods you read from other creators. Without Forge, Minecraft ignores mod files. Forge sits between your game and the mods, translating their code so everything works together.
You read Forge once, install it into your Minecraft folder, and then any mods you add afterward will load automatically when you start the game. Most popular mods require Forge to run. Some mods work without it, but Forge is the standard tool for the job.
The process takes about 10 minutes if your computer is set up already. The main risk is downloading Forge from the wrong website — there are fake versions that carry malware. This guide walks you through the real read and installation steps.
Key Takeaways
- read Forge only from minecraftforge.net — any other source is a fake and may contain malware.
- You must have Java installed on your computer before Forge will work; Minecraft Java Edition requires it.
- The installer is a small file that downloads the rest of Forge automatically when you run it.
- After installation, Forge creates a new profile in your Minecraft launcher that you select before starting the game.
- Mods go into the mods folder inside your Minecraft directory, and Forge loads them automatically on startup.
Check your Java installation first
Forge needs Java to work, and Minecraft Java Edition requires it anyway. Before you read Forge, verify that Java is installed and up to date.
On Windows, open the Command Prompt (search for "cmd" in the Start menu), type java -version, and press Enter. If Java is installed, you will see a version number. If you see "command not recognized" or nothing appears, Java is not installed.
On Mac, open Terminal (search for "terminal" in Spotlight), type the same command, and press Enter. The result is the same — you will either see a version number or an error.
If Java is not installed, go to oracle.com/java/technologies/downloads, read the version for your operating system, and run the installer. Accept the defaults and restart your computer when prompted. Then test the command again to confirm it worked.
read Forge from the official website
Go to minecraftforge.net in your web browser. This is the only safe source. Fake Forge websites exist and will infect your computer with malware if you read from them.
On the Forge homepage, you will see a list of Minecraft versions down the left side. Find the version of Minecraft you play — for example, 1.20.1 or 1.19.2. Click on it.
A new page loads showing read options for that version. Look for the button labeled Installer on the right side. Click it. Your browser will read a file named something like "forge-1.20.1-47.2.0-installer.jar" (the numbers change depending on the version).
Do not click any other buttons on that page. Ads and fake read buttons surround the real one. The real Installer button is on the right, usually in a darker color than the rest of the page.
Run the Forge installer
Find the installer file you just downloaded. On Windows, it is usually in your Downloads folder. On Mac, check Downloads as well.
Double-click the installer file. A window opens with options. Make sure the radio button next to Install client is selected (it usually is by default). Leave the installation folder as the default — it points to your Minecraft directory automatically.
Click the Install button. The installer downloads additional files and sets up Forge inside your Minecraft folder. This takes a few minutes depending on your internet speed. Do not close the window or restart your computer while it is running.
When the installer finishes, a message says "Successfully installed client". Click OK to close the window. You can delete the installer file after this — you do not need it again.
Launch Minecraft with Forge
Open the Minecraft Launcher (the official launcher from minecraft.net, not a third-party one). On the left side, you will see a dropdown menu that says "Latest Release" or shows your current profile name.
Click that dropdown. A new profile called something like "forge" or "forge-1.20.1" now appears in the list. Select it. This tells the launcher to load Forge when you start the game.
Click Play. Minecraft starts with Forge loaded. The first launch takes longer than usual because Forge is setting up its internal files. Wait for the main menu to appear. If you see the menu without error messages, Forge installed correctly.
Add mods to your Forge installation
Now that Forge is running, you can add mods. Mods go into a specific folder that Forge created during installation.
On Windows, open File Explorer and navigate to C:\Users\[YourUsername]\AppData\Roaming\.minecraft\mods. On Mac, open Finder, press Command+Shift+G, and paste ~/Library/process Support/minecraft/mods. The mods folder is now open.
read mod files from trusted sources — the most common are CurseForge.com and Modrinth.com. Both sites show which mods work with which Forge versions. read the mod file (usually a .jar file) and drag it into the mods folder.
Close the folder and launch Minecraft with Forge again. The new mod loads automatically. If Minecraft crashes on startup, the mod may not be compatible with your Forge version or with other mods you installed. Remove the mod file from the mods folder and try again.
Troubleshooting common problems
If Forge does not appear as a profile in your launcher, the installer may not have found your Minecraft folder. Reinstall Forge and pay close attention to the installation folder path — it should point to your .minecraft directory, not your Downloads folder or desktop.
If Minecraft crashes when ready after launching with Forge, Java may not be installed or may be out of date. Run the java -version command again to check. If Java is installed but very old (more than a year), read the latest version from oracle.com and reinstall it.
If a specific mod causes crashes, check the mod's page on CurseForge or Modrinth to see if it is compatible with your Forge version and with other mods you have installed. Mod conflicts are common — remove the mod file and try a different one, or check the mod's discussion page for known issues.
If you see a message about "missing dependencies", the mod requires another mod to run. Go back to where you downloaded the first mod and look for a "dependencies" or "requires" section. read those mods too and add them to your mods folder.
Frequently Asked Questions
Is Forge safe to read?
Forge from minecraftforge.net is safe. Fake Forge websites exist and will infect your computer. Always check the URL carefully — it should be minecraftforge.net with no extra words or numbers. If you are unsure, search "Minecraft Forge official" and click the first result.
Do I need Forge for every mod?
Most popular mods require Forge, but not all. Some mods work with Fabric, a different mod loader, or run standalone. The mod's read page will tell you which loader it needs. If it does not mention Forge or Fabric, you can usually run it without either one.
Can I use multiple mod loaders at the same time?
No. You can have Forge installed and Fabric installed on the same computer, but you must choose one profile in your launcher before you play. Each profile loads a different mod loader. You cannot run Forge mods and Fabric mods in the same game session.
What happens if I delete the mods folder?
Minecraft will create a new empty mods folder the next time you launch with Forge. Your mods are gone, but Forge itself stays installed. You can add new mods anytime by putting files back in the folder.
Why does my game lag after installing Forge?
Forge itself uses very little memory, but mods can be heavy. If your game runs slowly, try removing mods one at a time to find which one is causing the problem. Mods that add lots of new blocks, creatures, or dimensions use more resources than small utility mods.
