Every QR code produced by this site uses the standard QR model 2 format, so it is readable by the native camera app on iOS and Android as well as by dedicated scanner apps. There is nothing proprietary in the output and no account or app required for the person scanning.,If a code fails to scan, the cause is almost always one of three things: insufficient contrast, a quiet zone that has been cropped away, or a code printed too small for the content it carries. Increasing the error-correction level and printing slightly larger solves the great majority of real-world failures.
For print, download the SVG file and place it in your design tool at the size you need. Vector output stays sharp at any scale and avoids the pixelation that comes from enlarging a PNG. For screen use such as a slide deck or a social post, a PNG up to 2K resolution is usually the better choice because it is supported everywhere.,If you are printing on a curved surface such as a cup or a banner, test a proof first. Distortion changes the module geometry and can make an otherwise valid code unreadable, so a physical proof is always worth doing before a large run.
Yes. Every tool is free with no account, no watermark, no usage cap and no hidden upgrade. Unlimited generation and high-resolution downloads are included.
No. The codes are static, so the destination is built into the graphic itself. They keep working indefinitely as long as the target URL or content remains valid.
SVG for unlimited scaling and print, and PNG up to 2K resolution for screens and social. Transparent backgrounds are supported.
No. Encoding happens in your browser, so URLs, WiFi passwords and contact details never leave your device.
Yes. Place a logo in the centre and raise the error-correction level so the code still scans if part of the centre is covered.
