EasyInvoicePDF

EasyInvoicePDF is a free, open-source invoice generator that runs entirely in your browser. It features a live PDF preview that updates as you type, so you can see exactly what your invoice will look like before downloading.

No account or sign-up is required — your data stays local and is never uploaded to a server. It supports 10+ languages, 120+ currencies, customizable tax labels (VAT, GST, Sales Tax), QR codes for payments, and shareable invoice links.

Built with Next.js and React, it's a lightweight alternative to full accounting suites like FreshBooks for users who just need to generate and send professional invoices quickly.
