QR Code Generator
Create custom QR codes for URLs, text, emails, and WiFi networks in seconds.
How to Use
Select the data type (URL, Text, Email, or WiFi), enter the content, choose a size, and click Generate QR Code. The QR code appears instantly. Download as PNG or SVG for print or digital use.
How It Works
The QR code is generated using the Google Charts API, which encodes your data into a standard QR code format. All processing happens server-side via the API — no data is stored or logged. The resulting image can be downloaded and used anywhere.
Common Use Cases for QR Codes
- Restaurant menus — Create QR codes linking to digital menus that diners can scan from their phones. Contactless menus reduce printing costs and make updates instant when menu items change.
- Marketing materials — Add QR codes to flyers, posters, business cards, and brochures that link to your website, portfolio, or promotional video. Track scan rates to measure campaign effectiveness.
- WiFi sharing — Generate a WiFi QR code for your office or home network so guests can connect by scanning instead of typing a long, complicated password.
- Event ticketing — Issue QR codes on digital tickets that can be scanned at event entrances for contactless check-in, reducing queues and eliminating the need for printed tickets.
Tips for Effective QR Codes
- Test before printing — Always scan the generated QR code with multiple devices and apps before printing it on materials. A broken QR code on 10,000 flyers is an expensive mistake to fix.
- Ensure sufficient contrast — The QR code needs high contrast between dark and light modules for reliable scanning. Dark code on a white background is the most reliable combination. Avoid placing codes on busy or dark backgrounds.
- Leave white space around the code — The quiet zone (white border) around the QR code is essential for scanners to recognize it. Maintain a margin of at least four modules width on all sides.
- Choose the right size for the use case — Print QR codes large enough to scan from the expected distance. A code on a billboard needs to be much larger than one on a business card. As a rule, the scanning distance should be about ten times the code width.
Frequently Asked Questions
What can I create QR codes for?
You can create QR codes for websites (URLs), plain text, email addresses (with optional subject), and WiFi network credentials (SSID, password, and encryption type). The WiFi QR code allows users to scan and connect to your network instantly.
What sizes are available?
Choose from 150x150, 200x200, 300x300, or 400x400 pixels. Larger sizes are better for print materials and ensure scannability from a distance. Smaller sizes work well for digital displays and mobile apps.
Are these QR codes free to use?
Absolutely! All QR codes generated on our site are completely free with no watermarks, no expiration, and unlimited generation. Use them for personal or commercial projects without any restrictions.
How do I scan a QR code?
Most modern smartphones (iPhone and Android) have built-in QR code scanners in the camera app. Simply open the camera and point it at the QR code. A notification will appear with the encoded content.
Can I edit a QR code after generating?
Once generated, QR codes are static and cannot be edited. If you need to change the content, you must generate a new QR code. The new QR code will look different due to the encoding change. Always test QR codes before printing.
Do QR codes expire?
No, QR codes themselves never expire. However, the content they point to (like URLs) may change or become unavailable. For website QR codes, ensure the URL remains active.
What is the difference between a QR code and a barcode?
A standard barcode stores information in one dimension — a series of vertical lines read horizontally. It typically holds only a numeric identifier like a product code. A QR code stores data in two dimensions — both horizontally and vertically — allowing it to hold significantly more information including URLs, text, contact details, and WiFi credentials. QR codes also include error correction, meaning they can still be scanned correctly even if partially damaged or obscured.
Can I track how many people scan my QR code?
This tool generates static QR codes that encode the data directly into the image pattern. Static QR codes cannot be tracked. To track scans, you need a dynamic QR code service that uses a short URL which redirects to your actual destination. The redirect service tracks the number of scans, locations, devices, and timing. However, tracking services often require a paid subscription and may introduce dependency on a third-party service for your QR codes to continue working.
