What is QR Code Generator?

A QR code (Quick Response code) is a two-dimensional barcode that stores data such as URLs, plain text, WiFi credentials, contact cards, and more. QR codes are widely used in marketing, payments, event tickets, restaurant menus, product packaging, and business cards because they can be scanned instantly with any smartphone camera. This free QR code generator creates high-quality, fully scannable codes with Reed-Solomon error correction (Level M) entirely in your browser — no data is sent to any server. You can customize the foreground and background colors to match your brand, choose from multiple sizes (150px to 1000px), and download the result as PNG (for web and print) or SVG (for unlimited scaling). The generated QR codes have no watermarks, no limits, and no signup required.

Frequently Asked Questions

Can I use these QR codes commercially?+
Yes. The QR codes generated by this tool are completely free to use for any purpose — commercial, personal, educational, or otherwise. There are no watermarks, no attribution required, and no usage limits.
Are these QR codes scannable?+
Yes. This tool uses the industry-standard qrcode library with Reed-Solomon error correction (Level M), which means codes can be read even if up to 15% of the code is damaged or obscured. Every generated code is fully compliant with the ISO/IEC 18004 QR code standard.
Should I download PNG or SVG?+
Use PNG for digital displays (websites, social media, presentations). Use SVG for print materials (business cards, posters, flyers) because SVG scales to any size without pixelation.
Will custom colors affect scannability?+
QR codes require sufficient contrast between foreground and background. Dark foreground on light background works best. Avoid low-contrast combinations like light gray on white, or the code may not scan reliably.
Do QR codes expire?+
Static QR codes (like the ones this tool generates) never expire. They encode data directly into the pattern. Dynamic QR codes (from paid services) use redirect URLs that can be changed or deactivated.
Is my data sent to a server?+
No. The QR code is generated entirely in your browser using JavaScript. Your data never leaves your device. This makes it safe to generate QR codes containing sensitive information like WiFi passwords.
