About QR Studio
A free QR code generator that works in your browser and keeps your data on your device.
What QR Studio is
A free QR code generator and a layout editor that run entirely in the browser. You pick the data type, design the code with frames, colours, a logo and a caption, check that it scans and export it as PNG, SVG, JPG or a print-ready A4 sheet. No sign-up, no subscription, no expiry.
Why it is free
The site is static: there is no backend to pay for, no account system and no subscription. Codes are built by your own browser, so one visitor costs the same as a thousand. Nothing is hidden behind a paywall, and the codes you make keep working forever — they point straight at your link, not through our redirect.
How the codes are made
The QR matrix follows ISO/IEC 18004: four error correction levels, a standard quiet zone and untouched finder, alignment and timing patterns. On top of that we draw our own module and corner shapes — 14 and 12 of them — plus 335+ frames and illustrations. Every design is checked by a real decoder in the browser before you download it, and the indicator warns you when contrast or a logo makes the code unreadable.
Privacy
Links, Wi-Fi passwords, contacts, logos and photos never leave your device: generation, preview and export happen locally. Analytics, if enabled, loads only after you agree. Details are in the privacy policy.
