The quiet zone is the white space around the QR code. QR code scanners need some padding to detect the code edges. We recommend at least margin 1; higher values add more white space.

Free API keys are limited to 60 requests per minute. This is more than enough for most use cases. If you need higher limits, contact us.

The API returns JSON with a base64-encoded image (PNG or SVG), the payload string, QR type, size, MIME type, and generation timestamp. See the API docs for the full schema.

We store basic generation history (type, timestamp, size) for analytics but never the actual content of your QR code. Image uploads are stored temporarily for the Image QR type.

Never. We do not sell, share, or monetize any user data. See our Privacy Policy for full details.
