In short: A QR code generator encodes text, a URL, Wi-Fi details or contact data into a scannable two-dimensional barcode that phones can read with their camera.
About QR Code Generator
QR codes bridge paper and screens: a poster, a menu, a business card or a slide can send people straight to a web page. Many free generators, however, encode a short link on their own domain so they can track scans — or stop working unless you pay. The codes made here contain your content directly, so they keep working and nobody sits in the middle.
You can encode a URL, any text, or Wi-Fi credentials that phones can join with one tap. Choose the error-correction level (higher levels survive damage or a small logo overlay but make the pattern denser), the pixel size and the colors, and download a PNG for documents or an SVG that stays sharp at any print size.
How to use QR Code Generator
- Choose Link / text or Wi-Fi and enter the content.
- Adjust error correction, size and colors if needed — keep strong contrast with a dark code on a light background.
- Check the live preview with your phone’s camera.
- Download as PNG or SVG.
Examples
Enter the SSID and password with WPA security. Guests scan the code and their phone offers to join the network.
Encode your event URL, choose High error correction, and download the SVG so the code prints crisply at any size.
Frequently asked questions
Do these QR codes expire?
No. They contain your content directly, not a redirect link, so they keep working as long as the destination exists.
Is there a scan limit or tracking?
No. Because there is no redirect service, scans are not counted or tracked by anyone.
How much text fits in a QR code?
Up to about 2,900 bytes at Low error correction, less at higher levels. Shorter content gives a simpler, easier-to-scan code.
Why won’t my colored code scan?
Scanners need strong contrast. Use a dark foreground on a light background; inverted (light on dark) codes fail on many phones.
