How it works

A QR code is a two-dimensional barcode that stores text — a link, a message, WiFi login, or contact details — as a pattern of black and white squares any phone camera can read. This generator builds them entirely in your browser, so whatever you encode (including a WiFi password) never leaves your device.

Four content types are supported. URL and Text are straightforward. WiFi encodes your network name, password, and security type in the standard format phones recognize, so guests can join by scanning instead of typing. vCard packs a name, phone, email, and organization into a contact card that scanning adds straight to a phone's address book.

The error-correction setting controls how much of the code can be damaged or obscured while still scanning — higher levels add redundancy (and density) so a code survives a logo overlay or a smudge. You can adjust the pixel size and download the result as a crisp SVG for print or a PNG for the web. Codes are rendered as clean vector output for maximum scan reliability.

Examples

URL → point a phone camera at the code to open your link.

WiFi → guests scan to join without typing the password.

vCard → scanning saves your name, phone, and email as a contact.

Frequently asked questions

Do QR codes expire?

No. The code is a static encoding of your data, so it works forever as long as what it points to (like a URL) still exists. There's no server dependency.

What does error correction do?

It adds redundant data so the code still scans if part of it is dirty, damaged, or covered by a logo. Higher levels are more robust but make the code denser.

Is my WiFi password safe?

Yes. The code is generated in your browser and never uploaded. Only someone who scans the printed code can read the credentials, so share it as you would the password itself.

PNG or SVG — which should I download?

Use SVG for print or large sizes because it stays sharp at any scale. Use PNG for quick web use where a fixed-size image is fine.
