It is important to clarify that God of War III was never released for the PlayStation 2; it was developed exclusively for the PlayStation 3 and later remastered for the PlayStation 4. Because the game was built specifically to leverage the PS3's hardware, it cannot run natively on a PS2.
If you are looking for a "highly compressed" or "extra quality" ISO, you are likely looking for the original God of War (2005) or God of War II
(2007), which were the only mainline titles released for the PS2. How to Compress PS2 ISOs for Better Quality/Performance
For the actual PS2 titles (God of War 1 and 2), you can use specialized tools to reduce file size without sacrificing game quality:
CISO Compression: Use a tool like CISO GUI to convert standard .ISO files into .CSO (Compressed ISO) or .ZSO formats.
Set the compression level between 1 and 9 (9 is the highest compression).
This is ideal for playing games via OPL (Open PS2 Loader) on real hardware or emulators to save space on USB or SMB drives.
CHD Conversion: For the best balance of compression and performance on emulators like PCSX2, convert your ISOs to the .CHD format using chdman. This format provides excellent lossless compression. god of war 3 ps2 iso highly compressed extra quality
Extra Quality via Emulation: To get "extra quality" that exceeds the original console's capabilities, use the PCSX2 emulator to upscale the resolution to 4K, enable Anti-Aliasing, and use Texture Filtering.

Format: ISO / CSO Platform Emulated: PlayStation 2 File Size: Variable (typically 1.5GB - 3GB compressed)
RPCS3 is the only viable way to play God of War 3 on a PC. However, be warned:
For legitimate emulation (like PS1, PSP, or GBA games), “highly compressed” refers to converting a disc image (ISO, BIN, CUE) into formats like CSO, CHD, or PBP. These formats use lossless compression—like a ZIP file for games.
“Extra Quality” in the piracy scene usually claims that despite heavy compression (shrinking a 8GB+ game to 500MB), the graphics, audio, and cutscenes remain intact. This is technically impossible for 3D HD games. To achieve extreme compression, you must:
In short: You cannot have “highly compressed” and “extra quality” together. It’s a marketing lie to get clicks. It is important to clarify that God of

Downloading a "God of War 3 PS2 ISO" is a weird, fascinating experience. It is not the definitive way to play the game—that honor belongs to the PS3 or PS4 Remaster. However, as a "Highly Compressed" portable file for an emulator or a soft-modded PS2, it is a technical marvel.
Pros:
Cons:
Recommendation: If you want the real story, play the PS3/PS4 version. If you just want to hack and slash as Kratos on your phone or an old console and don't mind rough edges, this "Extra Quality" rip is a fun novelty.

I notice you're asking about a "God of War 3 PS2 ISO" — but I should clarify that God of War 3 was never released for the PlayStation 2. It was a launch title for the PlayStation 3 in 2010. Any website claiming to offer a "PS2 ISO" of God of War 3 is either mislabeled, a fake, or potentially malicious.
If you're looking for highly compressed, extra quality ISOs of actual PS2 God of War games, here are the legitimate entries in the series on that console:
First off, let’s address the elephant in the room: God of War 3 was a flagship title for the PS3, designed to push the Cell processor to its limits. Finding it on PS2 is like finding a Ferrari engine inside a Honda Civic. This ISO is a fan-made miracle—a demake/port that attempts to bring Kratos’ vengeance to the older generation.
If you downloaded this expecting the exact PS3 experience, you will be disappointed. But if you approach it as a technical curiosity or a "what could have been," the "Extra Quality" mod version is surprisingly impressive.
Because this is a compressed ISO, the audio is the first thing to suffer.
The phrase "Highly Compressed Extra Quality" is a massive red flag. Cybercriminals know that gamers looking for free, impossible files (a PS2 version of a PS3 game) are desperate. The "ISO" you download is often a .exe file, a crypto-miner, or ransomware.
