Free PromptPay QR code generator, right in your browser
Onova PromptPay QR Generator turns your PromptPay phone number, national or tax ID, or e-Wallet ID into a QR code that any Thai mobile banking app can scan to pay you. You can lock the QR to a fixed amount or leave it open so the payer decides. Everything is generated locally in your browser, so your details never leave your device, and you can download the QR as a PNG to print, share or add to an invoice.
How to create a PromptPay QR code
- Choose whether you are using a phone number, a national/tax ID, or an e-Wallet ID.
- Type in the PromptPay number or ID that should receive the money.
- Optionally enter a fixed amount in baht, or leave it blank for any amount.
- Download the QR as a PNG, then print it or share it with whoever is paying.
Your details stay private
This tool builds the PromptPay QR entirely inside your web browser. It creates a standard EMVCo PromptPay payload with the correct CRC checksum, exactly like the QR codes Thai banks generate, and encodes it as a QR image on your own device. Nothing is uploaded to a server, there is no sign-up and no watermark. It even works offline once the page has loaded.
