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 PrestigePDF — a completely free, no-signup online PDF toolkit with 22+ tools built with React, TypeScript, and WebAssembly.

Here's the story, the tech, and what I learned building it.

Why I Built It

Tools like ilovepdf and smallpdf are great but they push you toward paid plans fast — file size limits, watermarks, forced signups. I wanted something genuinely free with no limits for basic operations and no account required.

Also, being from Nepal, I wanted to prove that quality developer tools can be built and used globally from anywhere. The "Built from Nepal, used globally" badge on the About page is something I'm genuinely proud of.

What PrestigePDF Does

Everything you'd normally need Adobe Acrobat for — free, in your browser:

  • Merge PDF — combine multiple files into one
  • Compress PDF — reduce file size without quality loss
  • Split PDF — extract specific pages or ranges
  • PDF to Word / Excel / JPG — convert to any format
  • Edit PDF — add text, images, annotations
  • Protect / Unlock PDF — password management
  • Watermark, Rotate, Crop, Number Pages — and more

👉 Try it free at prestigepdf.com

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.
