QR code generator
Create a QR code for a web address, text, email, phone number or Wi-Fi details. Preview it and download it without uploading the contents.
Works locally in your browser
How this tool works
Turn supported text and contact payloads into a QR symbol generated entirely in the browser. The preview is an object URL that is revoked when replaced.
Inputs and definitions
Choose the content type, enter the requested fields, generate the code, test the preview with a separate scanner, then download the SVG.
Methodology
The tool builds an allowlisted payload format, escapes reserved Wi-Fi characters, and encodes it at medium error correction with a four-module quiet zone.
Assumptions
Scanner support varies by operating system and application. Wi-Fi and contact actions always require the scanning device to interpret the payload.
Worked examples
Worked example
Entering https://example.com creates an SVG whose encoded payload is exactly that HTTPS address.
Enter and review
Choose the content type, enter the requested fields, generate the code, test the preview with a separate scanner, then download the SVG.

Limitations and common mistakes
A QR code proves only what data it contains. It does not prove that a destination, network, payment request, or person is trustworthy.
Frequently asked questions
Can I create a JavaScript URL?
No. URL mode allows HTTP and HTTPS only.
Is Wi-Fi data private?
It stays local, but anyone who receives the QR image can read the credentials.
Why should I test the code?
Print size, contrast, damage, and scanner differences can affect recognition.
