About FreeInvoiceGen.app
What We Do
FreeInvoiceGen.app is a free online tool for creating professional invoices, receipts, and quotes. It features live PDF preview, multiple templates, multi-currency support, logo upload, automatic tax and discount calculations, and instant PDF download. Everything runs in your browser with zero server-side processing, so your business data stays completely private.
Why We Built This
Freelancers and small business owners need professional invoices, but most invoicing tools require monthly subscriptions, force account creation, or add watermarks to free versions. We built FreeInvoiceGen.app because creating a clean, professional invoice should be free and instant, with no strings attached.
Built by developers for freelancers, contractors, and small business owners, this tool prioritizes simplicity, privacy, and a professional result. Your client details and financial data never leave your browser.
Our Technology
FreeInvoiceGen.app is built with Next.js, React, and Tailwind CSS. PDF generation is handled entirely client-side using JavaScript. The tool supports draft saving via localStorage, multiple invoice templates, and live preview that updates as you type. The application is statically optimized for fast page loads across all devices.
