NumberTally QR Code Generator
Turn any text or URL into a QR code instantly — pick the size and error-correction level, then download it as a PNG for print, packaging, or signage.
What error correction does
QR codes include redundant data so they still scan when partly obscured. Level L recovers about 7% damage and makes the smallest code; M (15%) is the everyday default; Q (25%) suits outdoor or rough handling; H (30%) leaves room to overlay a small logo in the center. Higher levels make slightly denser codes.
QR tips for print
For printed materials, download the 400px version and keep the quiet zone — the white margin around the code — intact; scanners need it. Test-scan from the actual viewing distance before a big print run, and use short URLs (or a link shortener) so the code stays sparse and easy to scan.
Frequently Asked Questions
Is the QR code free for commercial use?
Yes. Codes you generate here are yours to use anywhere — packaging, menus, business cards, ads — with no watermark or attribution required.
Do the QR codes expire?
No. The code encodes your text directly (not a redirect service), so it works forever as long as the URL or text stays valid.
Can I put a logo in the middle?
Yes — choose error correction H (30%), download the PNG, and overlay a small centered logo covering no more than ~15% of the code. Always test-scan afterwards.
Is my text sent to a server?
No. The QR image is rendered in your browser (the encoding library loads once from a CDN). Your input never leaves the page.
Why does a long URL make a denser code?
More characters need more modules (the little squares). Shorten URLs first for cleaner, faster-scanning codes.
