Free QR Code Generator & Reader that works offline
Create a QR code for text or a URL, or inspect a QR image locally without sending its content to a remote service.
What this qr code generator & reader does
Generation uses a local QR matrix encoder. Reading uses the browser BarcodeDetector API when available; unsupported browsers show a clear compatibility message instead of uploading the image elsewhere.
How to use the QR Code Generator & Reader
- Paste or enter text for generation or a local QR image.
- Adjust the available options for the result you need.
- Choose Generate or read QR and review the output before using it.
- Copy or download the result, then clear the page if the input was sensitive.
Common uses
- Preparing QR codes for development and testing
- Inspecting copied data without sending it to a remote service

- Completing a browser-based workflow while offline
Private processing and offline access
This tool does not submit your input to a conversion server. Processing takes place inside the browser using local JavaScript and standard Web APIs. After the PWA has been installed or cached, the page and its core features remain available without an internet connection. Closing or clearing the page removes unsaved input; the tool does not create an account or cloud history.
Tips for accurate results
- Test generated codes with more than one scanner before printing them.
- Use a high error-correction level for labels that may be damaged.
- QR codes can contain unsafe links, so inspect decoded URLs before opening them.
