- Is this invoice generator really free, with no account required?
- Yes. There is no signup, no login, and no email address required. You fill in the form and click download. The PDF is generated in your browser using the open-source pdf-lib library. No data is sent to any server at any point.
- What currencies and tax rates does it support?
- You can select from 10 common currencies (USD, EUR, GBP, CAD, AUD, JPY, CHF, INR, SGD, NZD) using the currency dropdown. The currency symbol is shown in the PDF. For tax, enter any percentage from 0 to 100 — for example, 10 for 10% GST, 20 for 20% VAT, or 8.5 for a partial sales tax rate. Tax is calculated as: Tax = Subtotal × Rate ÷ 100.
- Can I add multiple line items and does the total update automatically?
- Yes. Click "Add line item" to add as many rows as you need. Each row has a description, quantity, and unit price — the line total (qty × unit price) and overall subtotal/tax/grand total all update in real time as you type. You can remove any row with the × button.
- What does the "Remember my details" toggle do?
- When enabled, your business name, address, and email (the "From" section) are saved to your browser's localStorage so they pre-fill the next time you open this page. This data never leaves your device. You can clear it at any time by toggling the switch off and reloading.
- Is the PDF suitable for professional use — can I send it to clients?
- Yes. The generated PDF contains your invoice number, issue and due dates, both parties' names and addresses, an itemized line-item table with quantities and unit prices, a clear subtotal/tax/total breakdown, and your notes or payment instructions. It is formatted cleanly and is suitable for emailing to clients or printing.
