How It Works
MultiWeb is a static website — just HTML, CSS, and vanilla JavaScript. There are no servers, no databases, and no backend. Here's what happens when you use a tool:
- Your browser downloads the page and its scripts once
- All processing happens locally using your device's CPU
- No data is sent to any server during tool usage
- When you close the page, all data is gone — nothing persists
This architecture means your files, calculations, and inputs never leave your device. It's privacy by design, not by policy.
Technology
MultiWeb is built with modern, lightweight web technologies:
- HTML5, CSS3, Vanilla JavaScript — No frameworks, no build tools, no bloat
- Google Fonts (Inter) — Clean, readable typography
- Service Worker — Enables offline caching and fast repeat visits
- CSS Custom Properties — Theming (light/dark mode) without JavaScript overhead
- Open Source Libraries — mammoth.js, pdf.js, SheetJS, QRious, jsPDF, and pdfmake for document and QR processing
- JSON-LD Structured Data — SEO-friendly markup for search engines
- Cloudflare Pages — Fast, global CDN hosting with automatic SSL
Privacy First
We take privacy seriously. None of our tools send your data to external servers. Everything runs locally in your browser using JavaScript. Your inputs, calculations, and files never leave your device.
The only cookies used are for analytics (Google Analytics) and advertising (Google AdSense), and only after you explicitly consent via our cookie banner. You can change or withdraw your consent at any time. See our Privacy Policy for full details.
