Project Overview

ImageComposer is a modern, feature-rich web application that provides comprehensive image processing capabilities directly in the browser. Built with privacy-first principles, it allows users to compress, enhance, convert, and optimize images without uploading them to external servers.

Purpose & Mission

The primary goal of ImageComposer is to provide professional-grade image processing tools while maintaining complete user privacy. Unlike traditional online image processors that require file uploads, this application processes all images locally in the user’s browser, ensuring data security and privacy.

Key Objectives:

• Provide client-side image processing capabilities
• Offer multiple image optimization features in one platform
• Ensure complete privacy and data security
• Deliver professional-quality results
• Support modern web standards and responsive design

Development Process

Architecture Overview

The application follows a modular, component-based architecture with clear separation of concerns:

src/
├── components/          # Reusable UI components
│   ├── image-composer/  # Image compression feature
│   ├── image-enhancer/  # Image enhancement feature
│   └── ui/             # Base UI components
├── hooks/              # Custom React hooks
├── lib/                # Core business logic
├── pages/              # Route components
├── types/              # TypeScript type definitions
└── utils/              # Utility functions

Development Workflow

1. Feature Development: Each feature is developed as a separate module with its own components, hooks, and utilities
2. Type Safety: Comprehensive TypeScript implementation ensures code reliability
