Features

Professional QR codes via a single POST

PNG, SVG & Base64
Choose your output format. PNG for images, SVG for scalable vector output, Base64 to embed inline.
Custom colours
Set foreground and background colours via hex codes. Dark QR on white, or white on brand colour.
Error correction
L, M, Q, or H correction levels. Use H when embedding a logo — up to 30% of the code can be obscured.
Custom size
Control output size in pixels. From thumbnail (128px) to print-ready (2048px+). No quality loss on SVG.
REST API
Simple POST endpoint with JSON body. Returns binary image or Base64 string. Works from any language.
Per-key quotas
