Paste a link or text, pick a size, download the image. Free forever.

Quick answer: Paste any URL or text above, pick a size and download the QR image — free, no sign-up. Tip: scan it with your own phone before sharing, and keep content under ~2,000 characters for reliable scanning. The QR itself never expires.

The QR image is created by a free public API — the text you enter is sent there to render the image.
