QR Code Generator
Runs locally
Turn any text or link into a QR code, or go the other way — upload an image of a QR code (up to 2MB) and see what it contains. Both directions run entirely in your browser.

How it works
Generation uses the open-source `qrcode` library to encode your text into a QR code image; scanning uses the open-source `jsQR` library to decode an uploaded image's pixel data. Neither your text nor your uploaded image is ever sent to a server.
Common use cases
- Creating a QR code for a URL, Wi-Fi network, or contact card
- Checking what a QR code on a poster, package, or document actually links to before opening it
- Generating a scannable code for a printed label or presentation
- Downloading a QR code as SVG for crisp printing at any size
Frequently asked questions
- Is my text or uploaded image sent to a server?
- No. Both generating and scanning QR codes happen locally in your browser using open-source libraries — nothing is uploaded.
- What's the file size limit for scanning?
- Uploaded images must be 2MB or smaller.
- What does the error correction level do?
- Higher levels (Q, H) let the QR code still scan correctly even if part of it is damaged or obscured, at the cost of a denser code. Medium (M) is a good default for most uses.
- Why didn't scanning find a QR code in my image?
- Make sure the QR code is reasonably clear and not too small or blurry in the image. Very low-contrast or heavily distorted codes may not be detected.
