Elegant QR codes. Auto-detection. Zero tracking. No subscription. Radical QR generates every code — links, contacts, Wi-Fi, events — entirely on your device. Paste anything, the app recognizes what it is and produces the right QR. Nothing is sent to a server. Nothing is stored without your consent. Built for the people who use QR codes every day — freelancers, restaurants, associations, entrepreneurs — and who want something beautiful, fast, and respectful of their privacy. WHY RADICAL QR • Auto-detect: paste a URL, a phone number, an email, a vCard, an iCalendar event, a Wi-Fi network — the app understands and produces the right QR, with the right encoding. • Right-click on the Mac, in any app: select a link, an address or any text and choose Services › Generate QR Code. In Finder it works on contact cards (.vcf) and calendar events (.ics) too — no need to open Radical QR first. • Written the way people write: paste "Dinner Saturday 8pm", "Wi-Fi: CafeGuest / Password: …", an email signature or an address, and get a calendar event, a Wi-Fi code, a contact card or a Maps link — filled in, in a small form you can adjust. • Settings you can see: every option draws its own result. Pick the corner you want, the eye you want, the size you want — there is nothing to read and nothing to guess. • Duplicate a code: point the camera at an existing QR, or pick a photo of one, and make it yours. Nothing is recorded, nothing is sent. • Clean export: PNG, JPEG, WebP for free; PDF and SVG vector in Pro, up to 4096 px. • Drag & drop: drop a text file, a vCard, or an .ics directly into the app. • 10 languages: English, French, German, Spanish, Italian, Portuguese, Japanese, Arabic, Hindi, Chinese. FREE Everything essential: auto-detection, duplicating an existing code, module and eye shapes, 6 preset colors and 3 preset gradients, PNG / JPEG / WebP export up to 512 px, system sharing. PRO (one-time purchase, lifetime) • Vector PDF and SVG export for print and large-scale use • Custom logo embedding with automatic quiet zone • Export size up to 4096 px • History with iCloud sync across your devices • Full color picker and custom gradients (linear, radial, angular, diamond) • Dot and leaf eye shapes • Up to four of your own styles, saved and brought back in one tap One purchase. Lifetime access. No subscription. OUR PRIVACY COMMITMENT • No analytics, no tracking • No logs, no telemetry • Your content never leaves your device • The camera reads a code live — no photo is taken, nothing is written • Pro history lives in your private iCloud container — never on our servers • We don't need to see what you encode — and we never will.

The call
