Create QR codes that are as beautiful as they are reliable. QR Atelier gives you a full design workshop — not just a generator. Start from a template or paste your own text or link. Create QR codes for Wi‑Fi, contact cards, email, phone numbers, SMS, locations, and profile links. Then style every detail: colours, module shapes, corner styles, centre logos, frames, quiet‑zone spacing, and error correction. The built‑in readability check keeps your designs practical. It warns you about low contrast, tight quiet zones, oversized logos, or rendering issues — so you never save or print a code that won't scan. Every design you make is saved in a local library. Reopen, edit, duplicate, and organise your work with project folders. When a design is ready, export it as a PNG (with or without background), share it with other apps, or copy the payload text for reuse. Need to scan? Use your camera to read QR codes and common barcode formats. Copy the detected value, open links, search non‑link text, or turn scanned content into a new QR design. You can also import an existing QR image from Photos and decorate it in the designer. No account required. Everything works offline right on your device. Perfect for creators, small shops, classrooms, offices, events, and everyday users who want QR codes that look great and scan every time. Download QR Atelier — design once, reuse forever.
