Instead of pasting a logo on top and hoping error correction survives, the image is encoded into the QR's data and error-correction bits, then rendered as a colour halftone. Every code is decoded back by a real reader and checked against its URL before it ships, so nothing unscannable goes out.</p> <p>Codes are dynamic: you can change the destination after printing, and you get scan statistics. Beyond links, sqr.art makes WiFi access codes and SEPA payment codes. Each code comes as PNG, print-ready SVG and PDF, in several styles.</p> <p>Preview for free without an account, and pay only when you like the result: 5 € once per code, yours for life. Subscriptions add unlimited codes, smart redirect rules (device, schedule, A/B) and CSV export (Pro), plus API, webhooks, batch generation and custom domains (Business). If a code does not scan in real life, it gets fixed or refunded.</p> <p>Popular for restaurant menus, business cards, wedding invitations, packaging, hotels and WiFi signs. The engine is open source (MIT, PHP).</p> design saas tools
