UPIQRTool is a web based application that generates UPI QR codes from an existing UPI ID, enabling users to create payment request codes directly in their browser without requiring an account or signup. The tool processes all data locally on the user's device, meaning entered details such as recipient name, UPI ID, optional amount, and note are not stored in the URL or transmitted to a server. Users can download the generated QR code as a PNG image, create a printable poster, or copy a payment link for sharing. The workflow is straightforward: the user provides a valid UPI ID (for example, name@bank) and the recipient's name. An amount and a note of up to 140 characters may be added, though these are optional. The prefilled amount is not a payment lock and the payer remains free to adjust it in their UPI app. The tool does not verify the UPI ID or generate tax receipts, transaction IDs, or reconciliation records. When uploading a logo or image to embed in the poster, the file must be under 4 MiB in size, with a maximum resolution of 8 megapixels and 4096 pixels per side; SVG and HTML files are not accepted. Common use cases include individuals or small business owners who need a simple way to request payments from customers or clients without relying on a dedicated payment platform. The generated QR can be downloaded, printed on posters or signs, or shared as a link. A Pro version offers additional features, though details are not enumerated on the main page. The tool is maintained at upiqrtool.com and is designed for quick, browser based use with no installation or registration required.
