Turn a link, a block of text, a Wi-Fi network or a contact card into a crisp QR code. Choose the size and error-correction level, then download it as SVG or PNG. Codes are generated on the fly in your browser and never expire.

Use the tool now Step by Step

Trusted & free

It is completely free, private and requires no signup.

IDs are not secrets

A UUID identifies a record — never use it as an authentication token.

Use crypto randomness

Math.random() is predictable. Use the CSPRNG for tokens, IDs and secrets.

Never trust a JWT blindly

Decoding is not verifying. Always validate the signature and claims on the server.

Keep secrets out of code

Generate keys here, then store them in environment variables or a vault.

How it works

Pick Text/URL for links, Wi-Fi to let guests join a network, or vCard for contact details.

The preview updates live as you type. Adjust the size and error-correction level for the best scan reliability.

Save it as vector SVG for print or PNG for screens and documents.

Examples & Data

Use case	Encoded data
Website link	https://password.brightcoding.dev
Plain text	Hello from Bright Coding
Wi-Fi	WIFI:T:WPA;S:MyNetwork;P:secret;;
vCard	BEGIN:VCARD...END:VCARD

Every type is compiled into the QR data automatically — no third-party redirect involved.

Frequently Asked Questions

No. They are static QR codes generated locally, so they are free, permanent and contain your data directly.

Higher levels keep the code readable even if part of it is dirty, covered or damaged, at the cost of a denser pattern.

Use SVG for printing, logos and large formats (it stays sharp), and PNG for quick sharing or embedding in apps.

The QR contains the network password so devices can join — only share it with people you trust.
