Use a simple endpoint to generate static QR SVGs for technical workflows.
Send text or a URL in the query string and receive static SVG QR artwork.
/api/qr?text=https%3A%2F%2Fqrcodeq.com&size=512&margin=4The API is intentionally plain: send text, get an SVG. It is not a secret store and should not be used for private data that you would not put in a URL.
It returns static SVG QR code artwork for the text or data in the request.
No. Query strings can appear in logs, browser history, and analytics. Keep private data out of simple URL-based requests.
Yes. The endpoint is useful for internal pages, documentation, dashboards, and quick generated previews.
The public endpoint returns SVG because it stays sharp at different sizes and is easy to cache. Use the browser tool when you need PNG or PDF downloads.
Cache by the full request URL. If the encoded text, size and margin are the same, the SVG can be reused instead of requested again.
SVG is a vector format that stays sharp at any size, from a thumbnail to a poster. It is also lightweight and easy to cache. If you need a raster image, convert the SVG to PNG on your server or use the browser tool.
The API is designed for internal tools and moderate use. For very high volume, consider generating QR codes locally with an open-source library so you do not depend on an external endpoint.
Yes. The same text, size, and margin settings produce the same SVG output, which makes caching straightforward. Store the result locally and skip the API call when the input has not changed.
Create a static QR code for the everyday jobs people actually print and share.
Paste a link and turn it into a scannable QR code for real-world materials.
Generate a set of QR files from a CSV without sending the sheet to a server.
Generate barcode SVGs from a simple endpoint for internal tools and prototypes.
