📦 File Compression Project

A portable and efficient file compression tool supporting Text, PDF, and Video files, with ready-to-run builds for both Windows and Linux.

---

🚀 Features

• 📄 Text Compression – Optimized compression for .txt files
• 📕 PDF Compression – DPI-based adjustable compression
• 🎥 Video Compression – Supports .mp4 and .webm with bitrate control
• ⚡ Portable Execution – No installation required
• 🧠 Smart file-type detection (not just extensions)
• 🖥️ Cross-platform builds – Windows & Linux

🖥️ How to Run

▶️ Windows

1. Download builds/windows_x64
2. Open terminal inside that folder
3. Run:

.\compressor <filepath> <level> <custom_value>

---

▶️ Linux

1. Download builds/linux_x64
2. Open terminal inside that folder
3. Give permission (first time only):

chmod +x compressor

4. Run:

./compressor <filepath> <level> <custom_value>

---

✅ Example

.\compressor input.pdf 2 150

---

⚙️ Parameters Explained

1. filepath

Path to the input file

Supported formats:

• .txt
• .pdf
• .mp4, .webm

---

2. level (Compression Level)

Level	Meaning	Notes
1	Low Compression	Best quality, least compression
2	Medium Compression	Balanced
3	High Compression	Smaller size, lower quality
4	Custom Compression	Requires custom_value

Use level 4 for full control.

---

3. custom_value (Only when level = 4)

📕 PDF → DPI

Value	Quality
300	High
150	Medium
72	Low

Lower DPI → higher compression

---

🎥 Video → Bitrate (kbps)

Value	Quality
2000+	High quality
1000	Medium
500	Low

Lower bitrate → smaller file

---

📄 TXT

• No custom value required
• Compression handled automatically

---

🧠 How It Works

• Detects file type using internal logic
• Routes processing:
  • PDF → Ghostscript
  • Video → FFmpeg
  • Text → Zstd compression
• Outputs compressed file in an output directory

---

📌 Notes

• Keep all binaries inside the build folder
• Works fully offline
• No installation required
• Just download the correct build and run
