Free QR Code Generator — URL, WiFi & More
Create free QR codes for URLs, text, WiFi, email, and phone numbers. Static codes that never expire. Works offline in your browser.
What is a QR code?
A QR code (Quick Response) is a two-dimensional barcode that you can scan with your phone. QR codes are widely used for URLs, WiFi passwords, business cards, and payments.
The QR code is generated entirely in your browser. No data is sent to a server.
How long does a QR code last?
The QR codes generated by this tool are static QR codes. The data (URL, text) is encoded directly into the pattern of the QR code itself. There is no server, database, or third party involved. This means your QR code never expires — it works forever, as long as the image exists.
This is different from dynamic QR codes offered by paid services. Dynamic QR codes use a redirect URL on a server, which can stop working if the service shuts down or your subscription expires. Our static QR codes have no such dependency.
Note: while the QR code itself never expires, the content it points to can change. For example, if you encode a URL and that website goes offline, the QR code will still scan but the link won't work anymore.
How the QR Code Generator Works
- Enter the URL, text, or data you want to encode
- Customize the size and error correction level
- Preview the QR code in real time as you type
- Download the QR code as a PNG image
QR Code Best Practices
QR codes can store URLs, plain text, Wi-Fi credentials, contact cards, and more. Use a higher error correction level (H or Q) if the QR code will be printed on materials that may get damaged or partially obscured. Always test your QR code with multiple phones before printing. For URLs, use a short link to keep the QR code simple and easier to scan.
When to Use a QR Code Generator
QR codes bridge the gap between physical and digital. Use them on business cards to link to your portfolio or LinkedIn profile, on restaurant menus for contactless ordering, on product packaging for instruction manuals or warranty registration, on event posters and flyers to link to ticket pages, and on Wi-Fi access cards so guests can connect without typing passwords.
Common Use Cases
- •Add a QR code to business cards linking to your portfolio or LinkedIn profile

Expert Tips
- ✱Use short URLs to keep QR codes simple and easier to scan from a distance
- ✱Always test your QR code with at least two different phone cameras before printing
- ✱Use error correction level H (30% recovery) for printed materials that may get scratched or partially obscured
Frequently Asked Questions
- A QR code encodes data into a two-dimensional grid of black and white squares. When you scan it with a camera, the device reads the pattern and decodes the stored information — typically a URL, text, phone number, or Wi-Fi credentials. QR codes use Reed-Solomon error correction, allowing them to be read even when partially damaged.
- Static QR codes generated by this tool never expire. The data is encoded directly into the pattern itself with no server dependency. However, if your QR code points to a URL and that website goes offline, the QR code will still scan but the link will not load. Dynamic QR codes from paid services can expire if your subscription ends.
- A QR code can store up to 4,296 alphanumeric characters or 7,089 numeric digits. However, more data means a denser, harder-to-scan code. For best results, keep your content short — use URL shorteners for long links and keep text under 300 characters.
- Error correction determines how much of the QR code can be damaged while still being readable. Level L recovers 7% damage, M recovers 15%, Q recovers 25%, and H recovers 30%. Use higher levels (Q or H) for printed materials that may get scratched or worn, and lower levels (L or M) for digital use where the image stays intact.
- This generator creates standard black-and-white QR codes for maximum compatibility. While colored QR codes are possible, dark-on-light contrast is essential for reliable scanning. Avoid light colors on light backgrounds, and always test a colored QR code with multiple devices before printing.
