I engineered and deployed a fully secure, 100% Client-Side PDF Tools Suite. It allows visitors to carry out high-overhead operations like PDF merging, splitting, compressing, and digital signing directly inside their sandboxed web browser, ensuring absolute user data privacy.
Key features implemented:
100% Local processing: Zero file uploads to external servers, protecting sensitive document data.
Drag-and-Drop file ingestion pipelines with rapid parsing.
HTML5 digital signature canvas for adding electronic signatures.
Premium slate dark theme with optimized responsive components.
Technologies used: HTML5, CSS3, vanilla JavaScript, Client-Side File Reader APIs, and local PDF rendering engines.
