Frequently Asked Questions

Is my data sent to a server?

No. The QR code is generated entirely in your browser. Your data never leaves your device.

What can I encode in a QR code?

URLs, text, phone numbers, email addresses, Wi-Fi credentials, and more. Up to 4,296 characters.

Can I customize the colors?

Yes. Choose any foreground and background color. Just ensure enough contrast for scanners to read the code.

What size should I use?

For print, use 600px or higher. For web and social media, 300-400px is usually sufficient.

Will the QR code have a watermark?

No. Your QR code is completely clean with no watermarks, logos, or branding added.

Can I use this for commercial purposes?

Yes. QR codes generated here are yours to use freely for any purpose — personal, commercial, or educational.

Does it work offline?

Once the page loads, QR generation works entirely offline since it uses WebAssembly in your browser.

What image format is the QR code?

QR codes are exported as PNG images with transparency support and crisp pixel-perfect rendering.

Do QR codes expire?

No. QR codes generated by FyleTools are static — they encode your data directly and never expire. They will work as long as the encoded URL or content remains valid.

How much data can a QR code hold?

Up to 4,296 alphanumeric characters or 2,953 bytes of binary data. For practical use, shorter content produces simpler QR patterns that scan faster and from greater distances.

Can I create a QR code for a Wi-Fi network?

Yes. Enter your Wi-Fi credentials in the format WIFI:T:WPA;S:NetworkName;P:Password;; and the QR code will let anyone scan to connect automatically.

Are colored QR codes still scannable?

Yes, as long as there is sufficient contrast between the foreground and background. Dark foreground on light background works best. Avoid very light colors for the QR pattern itself.
