Introducing PDFto.Tools: Your Open-Source, Private PDF Converter

TL;DR: PDFto.Tools is a free, open-source, and 100% client-side PDF converter. No servers, no waiting, no data leaks. Convert to DOCX, PNG, Excel, and more, right in your browser.

Why Another PDF Converter?

Online PDF converters usually ask you to upload your confidential documents to someone else’s server. That’s… sketchy. PDFto.Tools flips the script by running everything locally with WebAssembly (WASM). Your files never leave your device, and conversions finish before you can refill your coffee.

Privacy on Lock

Because every byte stays inside your browser sandbox, compliance-heavy teams (law, healthcare, finance—you name it) can finally breathe easy.

Transparent and Trustworthy

As an open-source project, our code is available for anyone to inspect. You don't have to take our word for it when we say your data is private—you can see for yourself. This transparency is the ultimate guarantee of security and trustworthiness.

Speed You Can Feel

WASM delivers near-native performance. We rebuilt proven PDF libraries like PDFium and LibreOffice as lean WASM modules, so multi-hundred-page documents convert in seconds—not minutes.

How It Works (Super Short Version)

Drag & drop your PDF into the app.
PDFto.Tools loads the file into a WASM module (think: tiny native app in your tab).
The module renders or re-encodes the document on the spot.
The browser hands you the converted file via a secure download—no middlemen.

That’s it.

Try It Live

👉 pdfto.tools — jump in, drop a file, and see the magic.

(Heads-up: Big files take a few extra seconds while the browser flexes its WASM muscles. Grab a quick sip of water.)

Roll Your Own Instance—Two Ways

Cloudflare Workers

# Fork + clone
git clone https://github.com/your-username/tools.git && cd tools

# Install Wrangler CLI
pnpm i -g wrangler

# Login + deploy
wrangler login
wrangler deploy

Done. Your worker URL looks like: https://pdfto-tools.<your-account>.workers.dev

Static Hosting (Vercel / Netlify / Pages)
```
pnpm install
pnpm build   # generates dist/
```
Upload the dist/ folder and you’re live.

Under the Hood: WASM Wizardry

We take heavyweight libraries—think PDFium & LibreOffice—compile them to WebAssembly, and serve them through a silky TypeScript frontend powered by Vite. The result? A snappy, single-page app that feels native but ships like a website.
