Mini Compressor

Toolset for game repacking — now with Masked Compression v3.0

---

📌 What is this?

Mini Compressor is a powerful all-in-one tool for game repacking and file compression. Think of it as a Swiss Army Knife — it combines multiple compression engines into a simple GUI, so you don’t have to deal with command-line tools.

It’s been tested over time and proven stable. The Masked Compression feature offers excellent compression ratios (if you’re willing to wait).
