FAQ

How much data can a QR Code hold?
Up to about 7,089 numeric characters, ~4,296 alphanumeric, or ~1,817 UTF-8 Chinese characters at maximum. Longer content makes denser, harder-to-scan codes. For URLs, run them through a URL shortener first.
Why won't my QR Code scan?
The most common culprits: image too small (at least 2×2 cm when printed), not enough contrast between the pattern and background, blurry or compressed image, or the quiet zone (white margin) is too narrow. Download at 512px, use black on white, and leave clear space around the edges.
How should I prepare it for print?
Download at 512px, import into your design software, and make sure there's a quiet zone of at least one module width around all four sides. Don't let other design elements crowd the edges or scanners may fail.
Can I add custom colors or a logo?
This tool generates standard black and white. Custom colors and logos are technically possible, but require enough contrast and raising the error correction level to H to keep it scannable — more risk of scan failures.
