QR codes & barcodes

Three: the QR Code Generator for text, URLs, Wi-Fi access, contacts, emails, and events; the QR Code Scanner, which reads codes using your camera or an uploaded image; and the Barcode Generator for EAN, UPC, Code 128, and Code 39. All are free to use without an account.

No. The generator creates static QR codes: the content is embedded directly in the code, with no redirect through our servers and nothing that could expire or be disabled. Once printed, the code works indefinitely.

Yes. You can choose any colors and add your own logo in the center. Download the finished code as a PNG or a losslessly scalable SVG — ideal for business cards, displays, or posters.

No. The generator and scanner run entirely in your browser: neither your QR code's content nor an uploaded or camera-captured image is sent to a server.

The higher the level, the more damage or obstruction the code can withstand, but the denser its pattern becomes. “Medium” is enough for most cases — “High” or “Very high” is useful mainly when adding a logo in the center or printing on difficult surfaces. When you upload a logo, the generator automatically sets error correction to the highest level.

No. The QR code scanner works without camera access — upload an image or screenshot containing the QR code instead. If you grant camera access, it automatically uses the rear camera on devices with multiple cameras.
