QR Code Generator turns text or a URL into a PNG QR code. Send the data you want encoded, and you get back a binary image response that you can download, store, or embed in your app.
Use size to control the output dimensions, from 1 to 40, with a default of 10. That makes it easy to generate compact codes for receipts and labels, or larger ones for posters, packaging, and print materials where scan reliability matters.
This is a straightforward fit for systems that need to render QR codes on demand: checkout pages, invitation flows, asset labels, event badges, or internal tools that attach machine-readable links to documents and products.
If you already have the destination text or link, QR Code Generator handles the image generation step and returns the PNG directly, without extra formatting or metadata.
