I Built a Free PDF Tool from Nepal — Here's What I Learned

I'm a full-stack developer based in Nepal and I just launched

The Tech Stack

• 
  Frontend: React + TypeScript + Tailwind CSS + Vite


• 
  PDF Processing: qpdf-wasm, PDF.js, jsPDF


• 
  Hosting: Contabo VPS + Docker + Nginx


• 
  Storage: AWS S3 for temporary file handling

The Hardest Part — PDF Processing in the Browser

The biggest challenge was making PDF operations fast and private. Most operations run client-side using WebAssembly (qpdf-wasm), meaning files never leave your device for most tools. This is a real privacy win compared to many competitors that upload everything to their servers.

Getting qpdf-wasm to work correctly with Vite took a couple of days of debugging — WASM workers, CORS headers, memory limits — all fun stuff.

Blog + SEO

I also built a blog section targeting long-tail keywords like "how to merge PDFs online free 2026". Since the site is brand new, I'm focused on blog content and backlinks right now before worrying about paid growth.

What's Next

• AI PDF features (summarize, Q&A with your PDF)


• More conversion formats


• Browser extension


• Mobile app

Try It + Feedback Welcome

If you work with PDFs regularly, I'd genuinely appreciate you giving it a try and dropping feedback in the comments. Early feedback from developers is gold.
