How to use the QR Code Generator

Type or paste any URL, text, WiFi credentials or contact info into the field above. Pick your brand colours and the QR code renders instantly. Hit Download QR Image to save a crisp high-resolution PNG that works everywhere.

Why use this QR code generator?

Everything runs locally, so codes for private links, WiFi passwords and contact cards never touch a server and never expire. There is no account, no scan limit and no watermark, so the code you test here is exactly the code you can print on packaging or a business card.

Step by step: create a scannable QR code

1. Type or paste what the code should contain — a URL, plain text, a WiFi login or contact details.
2. Set the foreground and background colours to match your brand.
3. Watch the live preview and confirm the code still scans as you change colours.
4. Click Download QR Image to save a high-resolution PNG.
5. Scan the saved file with two different phones before you print anything.

Tips for codes that scan every time

• Keep strong contrast — dark blocks on a light background scan best, and inverted codes often fail.
• Leave the white border (the quiet zone) untouched; cropping it is the most common reason a code will not scan.
• Shorter links produce fewer, larger blocks, which scan far more reliably when printed small.
• Test the printed proof, not just the screen, and try two or three different scanner apps.

Is it private and secure?

Yes. The QR code is generated entirely inside your browser using the qrcode library. Nothing you enter is ever uploaded, tracked or stored on any server.
