Tips
- Use high contrast colors for better scannability
- Minimum recommended size: 200x200 pixels for print
- Test your QR code with multiple scanner apps
- Consider adding a margin (quiet zone) around the code
- For large campaigns, use a URL shortener first

How It Works
This tool generates QR codes from URLs - two-dimensional barcodes that can be scanned by smartphones to quickly access web addresses without typing.
The QR generation process:
- URL encoding: The input URL is encoded into binary data suitable for QR encoding.
- Error correction: Reed-Solomon error correction is added so the QR code remains scannable even if partially damaged.
- Pattern generation: The data is converted into the characteristic black and white square pattern.
- Image output: The QR code is rendered as a downloadable image (PNG, SVG) in your chosen size.
QR codes bridge the physical and digital worlds, making it easy to share URLs in print, on screens, or in any situation where typing is inconvenient.

What to Know Before Using
URL length affects QR complexity
Longer URLs create denser, harder-to-scan QR codes. Use URL shorteners for long links to create cleaner, more reliable codes.
Error correction reduces capacity
Higher error correction (more damage resistance) means larger QR codes. Balance reliability with size based on your use case.
Test before mass production
Always test QR codes with multiple phones and scanning apps before printing. Lighting, distance, and angle affect scannability.
Size matters for scanning distance
QR codes need to be large enough for the scanning distance. As a rule: 1cm of QR code per 30cm of scanning distance.
Contrast is critical
QR codes need high contrast (dark on light). Reversed (light on dark) or low-contrast codes may not scan reliably.
Common Questions
What's the maximum URL length for QR codes?
Technically up to ~4000 characters, but practical limits are much lower. URLs over 100 characters create very dense codes. Use shorteners for URLs over 50 characters.
Can QR codes be customized with colors or logos?
Yes, but maintain contrast and don't cover too much of the code. Keep the three corner positioning squares intact. Test customized codes thoroughly.
Do QR codes expire?
The QR code itself doesn't expire, but the URL it contains might. If the destination changes, the QR code becomes useless. Use permanent URLs or redirect services.
What format should I download - PNG or SVG?
PNG for digital use and standard printing. SVG for large-format printing (banners, signs) as it scales infinitely without quality loss.
Why won't my QR code scan?
Common causes: too small, low contrast, damaged/corrupted, URL too long, or excessive customization. Test with multiple devices and scanning apps.
Are QR codes secure?
QR codes themselves are just encoded data. The risk is where they lead. Don't scan QR codes from untrusted sources - they could lead to phishing sites.
Can I track QR code scans?
Add UTM parameters to your URL before generating the QR code. Analytics will show traffic from the QR code separately from other sources.
