What is a QR code generator?
A QR code is a square pattern of dots that a phone camera can read in a moment. A QR code generator turns a web address, a message or other text into that pattern, so anyone can scan it instead of typing. This free tool creates the code inside your browser, and you can download it as a PNG image.
How to make a QR code
- Type or paste your link or text into the box. The code appears as you type.
- Choose a size. Large is best for printing, and medium suits most screens.
- Pick an error correction level if you need one (see below).
- Press Download PNG and save the image.
- Scan it with your phone before you print or share it.
What can you put in a QR code?
The most common use is a website link. You can also store plain text, a phone number written as tel:+923001234567, or an email address written as mailto:name@example.com. A Wi-Fi code can be written as WIFI:T:WPA;S:NetworkName;P:Password;; and most phones will offer to join the network when scanned. Longer content makes a denser code that is harder to scan, so keep it short.
Tips for a code that scans well
- Keep strong contrast. Dark dots on a light background work best, and light dots on a dark background may fail on some scanners.
- Leave a clear blank border around the code. This tool adds one for you.
- Print it at least 2 cm wide, and larger if people will scan from a distance.
- Use a short link when you can, because fewer characters mean a simpler code.
- Higher error correction lets a code survive scratches or a small logo on top, but it also makes the pattern denser.
Privacy
The code is drawn on your own device. The text you enter is not uploaded or stored by this tool. Remember that anyone can read what a QR code contains, so never put passwords or private data in a code you share publicly.
Frequently asked questions
Is this QR code generator free?
Yes. It is free, needs no account and has no scan limit.
Do these QR codes expire?
No. The code simply contains your text, so it keeps working as long as the link or information it points to is still valid.
Can I add a logo to the code?
This tool does not add logos. If you place one yourself, use high error correction and test the code carefully.
Why will my QR code not scan?
The usual causes are low contrast, a code printed too small or too much text. Increase the size, use dark on light and shorten the content.
What image format do I get?
A PNG image. Choose the large size for printing.
