QR code generator
Create a QR code, choose the size and error correction, and download a PNG. Every code is decoded before delivery to verify the output.
Verified before delivery
Every generated code is decoded with the same verifier Renderwolf runs against its own output. If decoding fails, the request returns an error instead of an image. Codes from any source can be checked with the QR verifier.
Error correction levels
M is a sensible default. Q and H add recovery capacity - the code tolerates more damage or obstruction - at the cost of a denser pattern. Payloads are processed transiently and never stored or logged. For styled codes with logos, generated by API, see Renderwolf.
