- Download: Select your preferred format (PNG, JPG, or SVG) and click "Download".
Pro-Tips for Scannability
Two common mistakes break QR codes: low contrast and inverted colors. Always ensure your foreground is significantly darker than your background. Most scanners cannot read a white code on a black background. Always test your code with your phone camera before printing.
What is Error Correction?
Error correction allows a QR code to be scanned even if part of it is damaged or covered. "High" (H) level withstands up to 30% damage, making it ideal for outdoor posters or adding logos. "Medium" (M) withstands 15% and is perfect for standard URLs and business cards.

Frequently Asked Questions
Do these QR codes expire?
No. The QR codes generated here are static. They directly encode your data and will work forever, as long as the destination URL is active. If you need to track clicks, use our UTM Builder before generating the code.
Is my data private?
Yes. This tool runs 100% in your browser using JavaScript. No data is sent to or stored on our servers, ensuring complete privacy for your links and text.
Can I use these for commercial print?
Absolutely. You can download the high-resolution PNG and use it on business cards, flyers, or product packaging. For best print results, use the "1024 x 1024" size option.
Why isn't my QR code scanning?
Ensure there is high contrast between the foreground (dark) and background (light). Also, check that the "Error Correction" level is high enough if the code is printed small. If you are using custom colors, ensure they contrast well.
