⚙️ Server Configuration (Important)

Edit your PHP configuration file:

sudo nano /etc/php/YOUR_PHP_VERSION/apache2/php.ini

📁 Required Folder Structure

Create required folders:

mkdir merge split uploads text_output compressed protected

Set proper permissions:

sudo chmod 755 merge/ split/ uploads/ text_output/ compressed/ protected/

🛠 Technologies Used

• PHP
• Ghostscript
• Poppler-utils (pdfunite, pdftotext, etc.)
• qpdf

---

🔐 Security Note

• Always validate uploaded files
• Restrict file types to PDF only
• Use escapeshellarg() when executing shell commands
• In production, avoid using 777 permissions — use proper ownership instead

---

📌 Recommended Production Setup

Instead of 777 permissions:

sudo chown -R www-data:www-data merge split uploads text_output compressed protected
sudo chmod -R 755 merge split uploads text_output compressed protected

---

💡 Future Improvements

• Add automatic file cleanup (cron job)
• Add progress bars for large uploads
• Add drag & drop UI improvements
• Add combined compress + protect tool
• Add Docker support
