What is QR Code Generator?
QR Code Generator is a free online tool that creates QR codes from any text or URL. You can customize the size and color of your QR code and download it as a high-quality PNG or SVG file for use in print or digital media. QR codes (Quick Response codes) are two-dimensional barcodes that can be scanned by any smartphone camera, making them an essential bridge between physical and digital content in marketing, events, and everyday information sharing.
How to use this QR Code Generator?
- Enter the text or URL you want to encode into a QR code in the input field.

Tips & Best Practices
Use Short URLs for Better Scanning
Shorter URLs produce simpler QR codes with fewer modules (black squares), making them easier and faster to scan, especially from a distance. Consider using a URL shortener for long web addresses before generating the QR code.
Choose SVG for Print Materials
SVG files are vector-based and can be scaled to any size without losing quality. Always choose SVG format when creating QR codes for posters, business cards, flyers, or any printed material where the code might be enlarged.
Maintain Sufficient Contrast
QR codes rely on contrast between the dark modules and the light background to be scannable. Always use a dark color on a light background. Avoid using light colors like yellow or light gray as the QR color, as this may make the code unscannable.
Test Before Printing
Always scan your generated QR code with at least two different smartphone cameras or QR reader apps before printing or publishing. What looks correct visually may not always scan properly, especially with custom colors or when the content is very long.
Common Use Cases
Business Cards and Marketing
Add a QR code to your business card that links to your website, portfolio, or LinkedIn profile. This gives recipients an instant way to access your digital presence without manually typing a URL. QR codes on flyers, brochures, and product packaging can drive traffic to landing pages, special offers, or product information.
Event Management
Generate QR codes for event tickets, conference check-ins, or Wi-Fi access. Attendees can scan a QR code to register, access event schedules, download presentation materials, or connect to the venue's Wi-Fi network — all without manual data entry.
Restaurant Menus and Retail
Create QR codes that link to digital menus, product catalogs, or order forms. Restaurants can place table-top QR codes that let diners view the menu on their phones, while retail stores can link to product reviews, sizing guides, or detailed specifications.
FAQ
What is the maximum amount of data a QR code can hold?
A QR code can hold up to about 3,000 alphanumeric characters. For best results, keep your content concise so the QR code remains easy to scan.
Can I use the generated QR codes for commercial purposes?
Yes. The QR codes you generate are completely free to use for any purpose, including commercial use, without any restrictions or attribution required.
What is the difference between PNG and SVG download formats?
PNG is a raster image format that works well for digital use such as websites, emails, and social media. SVG is a vector format that can be scaled to any size without pixelation, making it ideal for print materials like posters, business cards, and banners where the QR code may need to be very large.
How small can I print a QR code and still have it work?
The minimum recommended print size for a QR code is about 2 x 2 centimeters (approximately 0.8 x 0.8 inches). However, the minimum size depends on the amount of data encoded and the printing resolution. QR codes with less data can be printed smaller because they have fewer modules to distinguish.
Do QR codes expire or stop working?
QR codes generated by this tool are static — they encode the data directly into the image and never expire. The QR code will always decode to the same text or URL. However, if you encode a URL, the QR code will stop working if the destination website goes offline or the URL changes.
