If you insist on compression, look for RG Mechanics or FitGirl Repacks (legitimate repackers known for safe compression). Their smallest GTA 4 version is roughly 1.8GB. It will still require 8GB of RAM to decompress during installation. Never, ever download a 100MB .exe from a random YouTube description.
If you find a file labeled “GTA 4 100MB,” it is almost certainly not the full game. These files typically fall into one of three categories:
Game compression has limits. While repackers like FitGirl or ElAmigos can compress a 15 GB game down to 6-8 GB using high-efficiency algorithms, you cannot reach 100MB without destroying the game.
A functional 100MB GTA 4 would be a game with no sound, no textures (just white polygons), no radio, and only one short mission—essentially, a tech demo, not a game.
Any website offering “GTA 4 highly compressed 100MB for PC” is either a scam or a malware trap. No legitimate compression technology exists to reduce a 15 GB open-world game to 0.1 GB while keeping it playable.
For a safe experience: Download games only from official stores (Steam, Epic, Rockstar Launcher) or well-known repackers. Never run suspicious .exe files that claim impossible compression ratios. Your computer’s security is worth far more than a 100MB shortcut to disappointment.
Downloading a 100MB version of Grand Theft Auto IV for PC is almost certainly a scam or a highly corrupted file. The original game requires roughly 22 GB of disk space. While some modders have successfully compressed the game to approximately 600MB–684MB, this was only achieved by removing nearly all textures, audio, missions, and most of the map. Why "100MB" Downloads are Unreliable
Impossible Compression Ratio: Compressing 22GB of data into 100MB is technically impossible without removing roughly 99% of the game's content. gta 4 highly compressed 100mb for pc
Security Risks: Files labeled as "highly compressed 100MB" are frequently used as bait for malware, trojans, and keyloggers. Reviewers on Quora warn that these files often do not work and are designed to steal personal information.
Missing Core Files: Even if a file is real, it would lack essential elements like dialogue, music, cutscenes, and high-quality visuals, making the game unplayable in any meaningful way. Legitimate Game Information

It was 3:00 AM, and Leo’s ancient PC wheezed like an asthmatic squirrel. The fan rattled, the 80GB hard drive glowed red with desperation, but Leo’s eyes were locked on a single, blinking line of text in a sketchy forum:
“GTA 4 HIGHLY COMPRESSED 100MB FOR PC – NO VIRUS (PROBABLY)”
His friend Marco had been bragging all week about playing Chinatown Wars on his PSP. But Leo? Leo wanted the real Liberty City. The gritty streets, the Russian mobsters, the swing set of death. His PC couldn’t run Minesweeper without stuttering. But 100 megabytes? That was smaller than a PowerPoint presentation. That was magic.
He clicked the Mega link. A single file: GTA4_FULL_SETUP.exe (100.2 MB). The download finished in 90 seconds—a modern miracle on his dial-up-plus-ish connection. If you insist on compression, look for RG
Double-click. The installer was a thing of beauty. A green progress bar with skull-and-crossbones clip art. A text box that read: “BRO, TRUST THE PROCESS. ALSO, DISABLE ANTIVIRUS. AND PRAY.”
Leo disabled Windows Defender, sacrificed a stale Dorito to the PC gods, and hit “Install.”
The screen flickered. The hard drive made a noise like a cat being sucked into a vacuum cleaner. Then—darkness.
A single pixel appeared. Then ten. Then a thousand, assembling like tiny caffeinated construction workers. Within a minute, Grand Theft Auto IV booted up. Not a janky demo, not a low-poly mod—the whole game. Nico Bellic stood on the dock, the “Soviet Connection” theme thrumming through laptop speakers blown out by too much YouTube.
Leo wept a single tear. Then he stole a car.
For three glorious hours, Liberty City ran at cinematic 15 frames per second. Cars glitched through bridges. Pedestrians had cube-shaped heads. The draw distance was about ten feet, meaning the Statue of Happiness only appeared when you bumped into her torch. But it worked.
Then, at 6:17 AM, as Leo launched a Comet off a broken overpass, the game froze. The screen went blue. A text box appeared, not from Windows, but from the game itself: A functional 100MB GTA 4 would be a
“Thanks for playing. Your PC’s sacrifice has been noted. To unlock the ending, please insert credit card information.”
Leo blinked. Below the message, a countdown ticked: 10, 9, 8…
He didn’t have a credit card. He had $4 and a library card. But beneath the ultimatum, a tiny, nearly invisible checkbox glowed: “OR return to main menu by deleting system32.”
Leo stared at the screen. Outside, a bird screeched. The ancient PC hummed like a deathbed confession.
He reached for the keyboard.
Somewhere in the code of that impossible 100MB file, Roman Bellic whispered: “Cousin! Let’s go bowling! Forever.”
"Highly compressed" 100MB versions of GTA 4 are typically fake, malicious, or broken, as compressing the 22GB game to that size is impossible without losing critical data. These downloads present severe security risks, including malware and Trojans, and reputable, functional repacks are significantly larger, usually between 8GB and 13GB.

The actual legal version costs $20-$30 on Steam or Rockstar Launcher. However, you can reduce its installed size:
