What does the QR code generator do?
This QR code generator turns a link, a piece of text, an email address, a phone number or your Wi-Fi details into a code that phone cameras can scan. The codes are static: the information is stored in the pattern itself, so they don’t expire and don’t depend on a redirect service. You can create a QR code online here without signing up.
How to use the QR code generator
- Choose what the code should contain: a URL, text, email, phone number or Wi-Fi network.
- Fill in the details. The preview updates as you type and flags anything that can’t be encoded.
- Adjust the size, colours and error correction if you need to. Dark on light scans best.
- Download the code as PNG or SVG, and test it with your own phone before printing.
Your privacy
QR codes are generated entirely in your browser. The links, passwords and contact details you enter are never uploaded or stored by MyToolsLab.
Frequently asked questions
How do I make a Wi-Fi QR code?
Choose “Wi-Fi”, then enter the network name, password and security type. Guests can scan the code with their phone camera to join without typing the password. The Wi-Fi QR code generator runs in your browser, so the password isn’t sent anywhere.
Do these QR codes expire?
No. They are static QR codes, so the content is encoded directly in the pattern. They keep working for as long as the link or information inside them is valid.
Do I need an account to use this QR code generator online?
No. There is no sign-up, login or email address required. Open the page, create your code and download it.
Should I download PNG or SVG?
Use PNG for websites, documents and social media. Use SVG for print, signage or design software: it is a vector format, so it stays sharp at any size.
Why won’t my QR code scan?
The usual causes are low contrast between the colours, inverted colours (a light code on a dark background), or printing the code too small. Keep it at least 2 cm across for close-range scanning and leave a clear margin around it.
