No. This tool generates static QR codes that encode your URL directly into the pattern. They never expire and don't depend on any third-party service staying online. Once downloaded, the PNG works forever — unlike 'dynamic' QR codes from some services that stop working if you cancel a subscription.

Yes, completely. The QR code is generated in your browser and encodes only your URL. There's no watermark, no tracking, and no usage restriction. Print them on packaging, business cards, posters, or anywhere you like.

Yes, if you want to measure scans. Add utm_source=qr and utm_medium=print (or similar) to your URL before generating the code, so Google Analytics attributes the resulting visits to your QR campaign. Use our UTM Builder to create the tracked URL first.

A common rule is the code should be at least 1/10th of the scanning distance. For a poster scanned from 2 meters away, print the QR at least 20cm wide. For a business card scanned from 30cm, 2-3cm is fine. Always test a printed sample before mass production.

Common causes: too small for the scan distance, low contrast (always use dark code on light background), insufficient quiet zone (the white margin around the code), or printing on a curved/reflective surface. This tool includes a proper quiet zone and high error correction by default.

QR codes can encode plain text, Wi-Fi credentials, contact cards, and more — but for SEO and marketing purposes, URLs are the standard. This tool focuses on URL QR codes, which are the most useful for driving traffic to landing pages, menus, and reviews.

Indirectly. QR codes bridge offline marketing to your website, driving real visits that can improve engagement signals. Point them at a fast, mobile-friendly landing page with a clear next step. The scan itself isn't a ranking factor, but the traffic and conversions it generates support your broader goals.
