Our principles
🔒 No data uploaded — all processing happens in your browser. We never see your files, invoices, or tax numbers.
🚫 No signup required — every tool works immediately, no account needed.
💸 Free forever — the core tools will always be free. We may display ads to cover hosting costs.
📱 Mobile-friendly — all tools are designed to work on phones and tablets.
Why we built this
Most free tools online are free only up to a point — they ask you to sign up, limit the number of files you can process, or make you wait 30 seconds watching an ad before downloading your output. NxtCraft was built with a different philosophy: tools should just work, instantly, without friction.
We cover costs through non-intrusive advertising. Your data privacy is not the product — your attention is, briefly, via ads that don't interrupt the tool experience.
Built with
All NxtCraft tools are built with plain HTML, CSS, and JavaScript. No frameworks, no build tools, no servers. Fast to load, easy to audit, and private by design. Open source libraries used include pdf-lib, PDF.js, jsPDF, jsPDF-AutoTable, and qrcode.js.
