Create. Scan. Share.

Yes. Create and scan as many QR codes as you like — no signup, no watermark, and the codes never expire because they're static (the content is stored in the code itself).

No. Codes are drawn and scan-tested in your browser, and scanning reads camera frames or images on your device. Your recent history is saved only in this browser, and you can turn it off or clear it at any time.

Every design is automatically tested with a real QR decoder as you edit it. You'll see “Scan-tested” when it reads correctly, and a warning if the colors, logo size or density might cause problems — before you download anything.

Up to 30% of the code's width. Adding a logo automatically raises error correction to High, which lets the code survive the modules hidden behind the logo. Keep logos simple and high-contrast for the best results.

Never. It shows you the real website name first and checks for common QR-phishing tricks — hidden destinations, short links, look-alike characters, raw IP addresses and app downloads — and you choose whether to open it.

Yes. Upload or paste a photo or screenshot and QR Studio finds every QR code in it, each with its own result card.

At least 2–3 cm (about 1 inch) wide for close scanning, and larger for posters viewed from a distance — roughly 1 cm of code per 10 cm of scanning distance. Always test a printed sample with your phone first.
