How this service works

Generate SVG or PNG QR codes for links, text and standard payloads. Includes a four-module quiet zone, selectable error correction and validated foreground/background contrast.

Output

Returns a QR code image file (SVG or PNG) encoding the provided text, rendered at the specified pixel size with a four-module quiet zone, the chosen foreground/background hex colors, and the selected error correction level (M, Q, or H).

Example use cases

Event check-in QR code

“Make a 800px PNG QR code for https://eventbrite.com/e/12345 with black on white and H error correction — I need it printed on badges and it must survive some wear and tear.”

Branded SVG QR for marketing

“Generate an SVG QR code for https://mybrand.com using our brand green (#2d6a4f) as the foreground on a white background at 600px — I want to embed it in our digital brochure.”

WiFi credentials QR code

“Create a QR code for the text WIFI:T:WPA;S:GuestNetwork;P:welcome2024;; at 512px in PNG format with high error correction so guests can scan and connect easily.”

When to prefer

Choose this endpoint when you need a server-side QR code rendered as a proper image file (SVG or PNG) with validated color contrast, configurable error correction, and a standard quiet zone — especially useful when producing print-ready or embeddable QR codes at specific dimensions without relying on a client-side library.
