Modern EasyProPDF Website Rebuild

I’m ready to give EasyProPDF a fresh start. The current site feels dated, so the goal is a complete rebuild that looks modern and minimal, runs fast on every device, and puts a powerful suite of PDF tools front-and-center.

Here’s what I need delivered:
• A clean, responsive interface that follows modern-minimal design principles.
• Seamless, browser-based tools for Edit, Merge, Split, Compress, Convert, OCR, Sign, Protect, Watermark, plus an AI-powered chat assistant to help users extract, summarise or troubleshoot PDFs.
• Smooth workflow from upload to download—no clunky page refreshes.
• Robust code that can scale (language, framework and libraries are up to you; I’m open to suggestions as long as performance and security are top-tier).
• Clear hand-off: full source code, build instructions, and a brief walkthrough so I can maintain or extend the site later.

If you’ve built document or media processing platforms before, or have solid experience integrating PDF SDKs and AI APIs, that’s a bonus. Point me to similar work, outline your proposed tech stack, and let me know how quickly you can turn this around.
