🚀 Compress I/O

The Universal, Privacy-Focused Media Compressor.

Maintained by: Akshat Rawat
Repository: github.com/akshatrawat095/compress-io

Compress I/O is a lightning-fast, offline media compressor built with Tauri, Rust, and React. It uses your computer's dedicated hardware (GPU) to shrink video and image files without losing quality.

Unlike online converters, your files never leave your device.

✨ Key Features

⚡ Universal GPU Acceleration

Automatically detects and uses your hardware for maximum speed.

• ✅ NVIDIA: NVENC (RTX/GTX support)
• ✅ AMD: AMF (Radeon support)
• ✅ Intel: QuickSync (UHD/Iris/Arc support)
• ✅ Apple: VideoToolbox (M1/M2/M3 & Intel Mac support)

🛡️ Hybrid Engine (Crash-Proof)

Uses a smart "Hybrid Mode" (CPU Reads → GPU Writes) to ensure stability even on massive 8K files or corrupted inputs.

🎬 Universal Playback Fix

Automatically standardizes video pixel formats (yuv420p), ensuring your compressed videos play perfectly on:

• Windows Media Player / QuickTime
• Smart TVs & Consoles
• iPhones & Android devices

🔒 100% Offline & Private

No cloud uploads. No file size limits. No watermarks. Your data stays on your machine.

❓ FAQ / Troubleshooting

Q: Why does Task Manager show 0% GPU usage?

• A: Windows Task Manager often hides the "Video Encode" graph. Switch the graph from "3D" to "Video Encode" to see the work happening.
• Note: On laptops, ensure you plug in your charger for maximum GPU speed.

Q: My 4K video size didn't drop significantly. Why?

• A: The app prioritizes Quality and Compatibility. If your input was already highly compressed (H.265), the app converts it to the more compatible H.264 format while maintaining visual fidelity, which limits size reduction.
