What is Invoice Studio?
Invoice Studio is a free invoice, quote, and receipt maker. It runs in your browser. Your documents stay on your computer.
How Invoice Studio works
Invoice Studio is a free, private invoice, quote and receipt maker. It runs entirely in your browser as an installable PWA. Your documents never leave your device.
Everything happens on your device
There is no server and no backend. When you create a document, your browser does all the work — calculating totals, formatting currency, and drawing the PDF. Nothing you type is ever sent over the network. The site's Content-Security-Policy (connect-src 'self') even blocks the page from making outbound requests, so the privacy guarantee is enforced by the browser itself.
Where your documents are stored
Saved documents and your business profile live in your browser's IndexedDB — a local database that survives reloads and offline use. They are never uploaded. Clearing your browser storage removes them, so export anything important to PDF.
Offline-capable PWA
Install Invoice Studio to your home screen or desktop. A service worker caches the app shell, so you can keep creating and editing documents with no internet connection at all.
Branded PDFs, no watermark
Add your business name, logo and accent color in the profile, then export a clean, branded PDF in one click — or print straight from the live preview. The PDF is generated in your browser; there is no conversion server.
What about Pro features?
The free tier is fully usable: invoices, quotes and receipts, the Modern template, multi-currency, tax/discounts, and one-click branded PDF export. Invoice Studio Pro adds the Classic & Minimal templates, batch export (download many documents as a ZIP or one combined PDF), and recurring schedules with due reminders. Pro is a one-time, client-side license key — no subscription, no account, and the key is validated entirely in your browser (no license server). Unlock Pro →
