Convert text or URLs into QR code images with configurable size and error correction.

How it works
We URL-encode your text and pass it to the goqr.me API as a query parameter. The API encodes your data using Reed-Solomon error correction and returns a QR code PNG at the size you choose. Your text is sent as a URL parameter in a standard HTTPS GET request.
Frequently Asked Questions
What is the error correction level for?
Error correction lets a QR code be scanned even if it is partially obscured or damaged. Higher levels (Q, H) store more redundant data, so the code can still be read if up to 25–30% of it is covered — useful when you overlay a logo on top of the QR.
How much text can a QR code hold?
A standard QR code can hold up to about 3KB of alphanumeric data. In practice, keep URLs short — long data produces denser codes with smaller modules that are harder for phone cameras to scan reliably.
