📱 QR Code Generator

Our free QR Code Generator creates custom QR codes instantly. Enter any URL or text, choose size, and download. Perfect for business cards, restaurant menus, marketing materials, event check-ins, and Wi-Fi sharing. No sign-up, no ads, no tracking.

How it works: Paste your URL or text. Select QR size (small/medium/large). Click Generate. Download as PNG. The QR pattern encodes your data using Reed-Solomon error correction — even if partially damaged, it still scans. Works with any smartphone camera.

Best practices: (1) Test before printing — scan with multiple phones. (2) Minimum 2×2 inches on printed materials. (3) White background with dark foreground. (4) Keep URLs short (use bit.ly). (5) Add a call-to-action ('Scan for discount code').

Common uses: Restaurant QR menus (scanned 50M+ times during COVID), business cards linking to LinkedIn profiles, flyers to landing pages, product boxes to manuals/warranty registration, event badges to attendee profiles, and in-store displays to online reviews.
