Overview
The QRtag QR Code API generates clean, scan-ready QR code images from any URL or text with a single GET request — no authentication or signup required. You can control the output size by appending a size suffix to the API endpoint and receive either a PNG or SVG image directly. It also doubles as a simple URL shortener, making it useful for print materials, event tickets, and product packaging workflows.
Beginner Tip
No account or API key is needed — just construct a URL like https://api.qrtag.net/api/qr_10.svg?url=https://example.com and paste it into a browser or img tag to instantly see a QR code. The number after "qr_" sets the image size in centimetres (1-40). For a first test, try the SVG format as it scales perfectly at any resolution.

const data = await response.json();
console.log(data); What Can You Build?
