Image Size Compressor

A Flask web application that compresses images to reduce file size while maintaining quality. Upload your images and specify the target file size in KB, MB, or GB.

Features

• 🖼️ Multiple Format Support: JPG, JPEG, PNG, GIF
• 📏 Flexible Size Targets: Compress to specific KB, MB, or GB sizes
• 🎯 Quality Optimization: Iterative compression maintains best possible quality
• 🌐 Web Interface: Easy-to-use upload and download interface
• ⚡ Fast Processing: Efficient compression algorithm

Setup Instructions

Prerequisites

• Python 3.7 or higher
• pip (Python package installer)

Installation

1. Clone or download the repository to your local machine

2. Navigate to the project directory:

   cd Image-size-compressor

3. Create a virtual environment:

   python -m venv venv

4. Activate the virtual environment:

   • Linux/Mac:

     source venv/bin/activate

   • Windows:

     venv\Scripts\activate

5. Install required dependencies:

   pip install -r requirements.txt

Running the Application

1. Start the Flask server:

   python img_compressor.py

2. Access the application:

   • Open your web browser and go to: http://127.0.0.1:2000
   • The browser should automatically open to the application

3. Using the compressor:

   • Upload an image file (JPG, JPEG, PNG, or GIF)
   • Specify your desired file size
   • Choose the size unit (KB, MB, or GB)
   • Click compress and download your optimized image

After Compression

Technical Details

• Framework: Flask 2.2.3
• Image Processing: Pillow (PIL) 9.5.0
• Compression Method: Iterative quality reduction
• Supported Formats: JPG, JPEG, PNG, GIF
• Target Sizes: KB, MB, GB

Troubleshooting

Common Issues:

1. Import Error: Make sure you've activated the virtual environment
2. Port Already in Use: The app runs on port 2000 by default
3. File Upload Issues: Check that your image is in a supported format
4. Permission Errors: Ensure the uploads/ and static/compressed/ directories are writable
