About

Tools that work without an account or upload

Every tool here runs entirely in your browser. QR codes are generated client-side. Invoice PDFs are built with pdf-lib directly on your device. EMI calculations and unit conversions never touch a server. Your data stays private.

The Invoice Generator supports 7 tax regions with correct logic for each — India splits CGST+SGST automatically, Canada auto-fills HST/GST/PST by province (including Quebec QST), EU handles reverse-charge for B2B. Add a logo, discount, choose from 3 PDF templates, and sign in with Google to sync your profile and invoice history across devices. The EMI Calculator includes a reverse mode (how much can I borrow?) and a full year-by-year amortization table.
