I developed a comprehensive, web-based file manipulation platform offering over 30+ tools for image conversion, PDF management, and file compression. The system utilizes a hybrid backend architecture to process complex file formats (AVIF, HEIC, PDF) efficiently while delivering a seamless, real-time user experience.
⚙️ Hybrid Image Processing Engine
- Engineered a smart format handling system that dynamically selects between GD Library for speed (JPG, PNG) and ImageMagick for complex formats (HEIC, AVIF, SVG) to optimize server performance.
- Implemented advanced conversion logic capable of flattening transparencies for JPG output, preserving alpha channels for PNG, and handling animated GIFs.
- Built a robust job-tracking system that generates JSON status files to monitor conversion progress in real-time, updating the UI from "Pending" to "Processing" to "Completed".
📄 Automated PDF Manipulation
- Developed a PDF-to-Image pipeline that renders high-resolution pages using Ghostscript/ImageMagick and automatically packages the output into a downloadable ZIP archive.
- Created a scalable architecture supporting diverse PDF operations, including splitting, merging, and compression, accessible via a unified API endpoint.
- Integrated automated cleanup routines to securely remove temporary input files and intermediate artifacts immediately after processing to conserve server storage.
💻 Reactive Frontend & UX
- Designed a responsive, no-refresh interface using AJAX and Tailwind CSS, featuring live progress bars that track upload and server-side processing status.
- Implemented client-side validation to restrict file types before upload, reducing server load and improving user feedback loops.
- Structured a modular layout system using PHP output buffering (ob_start) to dynamically inject page-specific content into a universal master template for consistent branding.
🛡️ Secure & Scalable Backend
- Implemented strict MIME-type validation and error handling to prevent malicious file uploads and manage server-side exceptions gracefully.
- Built a directory-based job isolation system, ensuring that concurrent user requests do not conflict by generating unique transaction IDs for every conversion task.
