How this service works
Generate a QR code as PNG or SVG from any text or URL (up to 2000 chars, 64-2048 px). Pairs with the PDF endpoint for payment links and labels. Use when you need a scannable QR image for a URL, payment link or label.
Output
Returns a QR code image file — either a PNG bitmap or an SVG vector — encoding the provided text or URL. The image dimensions are determined by the requested size parameter (64–2048 px).
Example use cases
QR code for a payment link
“Create a 512px PNG QR code for this Coinbase Commerce payment link https://commerce.coinbase.com/pay/abc123 so I can print it on an invoice.”
SVG QR code for a product label
“Generate an SVG QR code for the URL https://myshop.com/products/widget-pro at 256 pixels — I need to embed it on a product label.”
QR code for a Wi-Fi login
“Make a 400 pixel PNG QR code that encodes the text WIFI:S:MyNetwork;T:WPA;P:hunter2;; so guests can scan and connect to my Wi-Fi.”
Technical details
Endpoint
POSThttps://toolrail.dev/qr?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, programmatic QR code image (PNG or SVG) from any text or URL, especially when chaining with the Toolrail PDF endpoint to produce payment links or printable labels. It is ideal for agent workflows that generate invoices, shipping labels, or product packaging requiring a scannable code without relying on a browser-based tool.
