Frequently Asked Questions

Can I scan the generated QR codes with any phone?

Yes. The QR codes generated by this tool follow the standard QR code specification and can be scanned by any modern smartphone camera or QR code scanning app on both iOS and Android devices.

How much data can a QR code hold?

QR codes can store up to approximately 2,953 bytes of data. For practical use, short URLs and text up to a few hundred characters work best. This tool supports content suitable for QR code versions 1 through 10.

Can I customize the colors of my QR code?

Yes. You can change both the foreground (dark module) color and background color using the color pickers. Make sure there is enough contrast between the two colors so scanners can read the code reliably.

Is my data private when generating QR codes?

Absolutely. This tool generates QR codes entirely in your browser using JavaScript. No data is sent to any server. Your content stays completely private on your device.

What size should I choose for my QR code?

For digital use (websites, emails), 300x300 pixels works well. For print materials like posters or business cards, choose 400 or 500 pixels to ensure the code remains scannable when printed at various sizes.

QR Code Types — Which One Do You Need?

This tool supports five QR code types. Each encodes different data and triggers a different action when scanned.

🔗

URL

Opens a website when scanned. The most common QR code type — perfect for business cards, menus, and marketing materials.

📝

Text

Displays a plain text message when scanned. Good for short notes, codes, or instructions.

📶

Wi-Fi

Connects the scanner's phone to a Wi-Fi network automatically — no password typing needed.

📧

Email

Opens the phone's email app with the recipient address pre-filled and ready to send.

📞

Phone

Opens the phone's dialler with your number pre-filled so the user can call you in one tap.

Tips for Creating Effective QR Codes

  • 1
    Always test before printing. Scan your QR code with at least two different phones before committing to a print run.
  • 2
    Keep URLs short. Longer URLs create denser, more complex QR codes that are harder to scan. Use a URL shortener if your link is very long.
  • 3
    Maintain high contrast. Dark on light always works best. Avoid light-coloured foregrounds on white backgrounds.
  • 4
    Add a call to action near the QR code. "Scan to visit our menu" tells people what to expect. QR codes without context get ignored.
  • 5
    Leave white space around the QR code. QR codes need a clear quiet zone around them to scan correctly. Don't crop the code too tightly in your design.

Frequently Asked Questions

Can I scan the generated QR codes with any phone?
Yes. QR codes generated by this tool follow the international QR code standard (ISO/IEC 18004) and can be scanned by any modern smartphone camera or QR code scanning app on iOS and Android. Most phone cameras can scan QR codes natively without a separate app.
Do QR codes expire?
Static QR codes generated by this tool never expire. The QR code permanently encodes whatever content you enter. However, if the URL your QR code points to goes offline, the code will scan successfully but lead nowhere. Always make sure the destination URL is permanent before printing.
How much data can a QR code hold?
QR codes can store up to approximately 2,953 bytes of data. For practical use, short URLs (under 100 characters) and brief text work best for reliable scanning. Very long URLs create dense QR codes that are harder to scan when printed small.
Can I customise the colours of my QR code?
Yes. You can change both the foreground and background colours using the colour pickers. Always ensure strong contrast — dark foreground on a light background is the most reliable combination.
Is my data private?
Absolutely. QR codes are generated entirely in your browser. No data is sent to any server. Your URLs, Wi-Fi passwords, email addresses, and phone numbers are never stored or transmitted.
Can I use the QR code for commercial purposes?
Yes. QR codes generated by ToolsNest are yours to use however you like — on business cards, product packaging, marketing materials, and any commercial application. There are no usage restrictions or licensing fees.
Does this work on mobile phones?
Yes. ToolsNest is fully mobile-responsive. You can generate and download QR codes directly from your phone browser without installing any app.
