QR Code Designer - Custom QR Code Generator

Foreground/background colors, size, margin, error correction level (L/M/Q/H), eye styles (square/circle/rounded), and dot styles (square/circle/dots/star). The page warns when contrast is weak — readers with color-vision differences may struggle with low-contrast pairs, so favor contrast over brand colors when in doubt. Center logo embed is not supported; use the plain QR generator when you just need a fast monochrome code.

PNG bitmap and SVG vector: SVG suits print scaling, PNG suits everyday sharing. Fancy modules or weak contrast lower the scan success rate — test on a real device before shipping.

Higher levels recover more damage but make the code denser and harder to print clearly at tiny sizes. Posters and large prints can afford a higher level; small on-screen codes or long payloads actually scan worse with excessive correction. If a styled code stops scanning, raise the level one notch first, then fall back to square modules.

A dark foreground on a light background is the safe default; inverted color schemes deserve repeated testing on real devices. Fancy modules like stars and dots trade away fault tolerance, so keep a conservative style for outdoor or long-distance scans; when print size is small, raise the error correction level or simplify the dots. Keep the payload short too — shorter codes are sparser and scan more easily.

Confirm the destination stays reachable — if a dynamic short link dies, even a beautiful code opens nothing. And never bake token-bearing URLs into codes meant for long-term display.
