How to use QR Code Generator?

Frequently Asked Questions
What data can I encode in a QR code?
URLs, plain text, email addresses, phone numbers, SMS text, WiFi credentials, contact info (vCard), calendar events, or any text up to ~4,000 characters. QR codes are versatile and unlimited in use cases.
What is error correction level?
Error correction allows QR codes to remain scannable even if partially damaged or obscured. Level 1 (7% recovery), Level 2 (15% recovery), Level 3 (25% recovery), Level 4 (30% recovery). Higher levels create larger codes.
What file format should I use?
PNG is standard and widely supported. SVG is scalable (good for print). PDF is printable at exact sizes. Choose PNG for web, SVG for logos/print, PDF for documents.
Can QR codes be tracked?
No, unless they link to a URL you control. The code itself is static. If it links to your website, you can track visits via analytics. The code itself contains no tracking.
What is the maximum data a QR code can hold?
About 4,296 characters for plain text, 2,953 for URL/binary. Larger data creates larger codes. Complex URLs with many parameters will produce visibly bigger QR codes.
Can I embed a logo in my QR code?
This tool generates standard QR codes without embedded logos. Advanced tools allow logo overlay, but ensure sufficient error correction (Level 3+) so it remains scannable.
Is it safe to scan unknown QR codes?
No. Unknown QR codes could link to malware or phishing sites. Most phones show the URL before opening. Verify the link looks legitimate before scanning, especially from untrusted sources.
How do I use a QR code for WiFi?
Format: WIFI:T:WPA;S:SSID;P:PASSWORD;; Most modern phones can scan and auto-connect. This tool can generate this format if you paste the WiFi string, or use a WiFi QR code generator.
