What can a code contain?

Any text: URLs, plain text, vCard contacts, Wi-Fi credentials or payment strings, up to the QR capacity for the chosen error-correction level.

Which formats are returned?

PNG by default, SVG for crisp scaling, or a base64 PNG data URL inside JSON for embedding.

What is error correction?

Levels L, M, Q and H trade capacity for damage tolerance. H survives about 30% of the code being obscured, which is what you want when placing a logo on top.

Can I change the colours?

Yes. Foreground and background colours are parameters. Keep strong contrast so scanners still read the code.

What does a call cost?

1 token per image. The free plan covers 500 codes a month.

QR Code Generator API

QR codes for any text or URL as PNG, SVG or base64, with size, margin, error correction and colours

Turn any text or URL into a scannable QR code as PNG, SVG or a base64 data URL, with control over size, margin, error-correction level and colours. Generated in the worker on every call, nothing stored.

Every call needs an X-Api-Key header. A free key includes 500 tokens a month, no card required. 1 token per call, so the free plan covers about 500 calls a month.
