Frequently Asked Questions
Q:
Is my data stored on your servers?
Absolutely not! All QR code generation happens entirely in your browser using JavaScript. Your data never leaves your device, ensuring complete privacy and security. We don't see, store, or track any of your content.
Q:
How does auto-formatting work?
Our smart detection analyzes your input and recognizes the content type (URL, phone, email, etc.). It then applies the optimal formatting - like adding "tel:" for phone numbers or "mailto:" for emails - to ensure maximum compatibility with all QR scanners and devices. You can always choose to disable this and use your raw input.
Q:
What size should I choose for printing?
For digital use (websites, emails, presentations), Medium (256px) is perfect. For printing on business cards or flyers, use Large (512px). For posters, banners, or large displays, choose XL (1024px). The rule of thumb: 1 inch of printed QR code needs at least 100-150px of resolution.
Q:
Do phone numbers need country codes?
For best results, yes! Include the country code with a + prefix (e.g., +1 for US, +44 for UK, +91 for India). This ensures the QR code works internationally. Our tool will format it with "tel:" prefix for direct calling functionality.
Q:
Can I create WhatsApp QR codes?
Yes! Select "WhatsApp" type or use Auto-Detect with a phone number starting with +. The tool will automatically create a wa.me link that opens a WhatsApp chat when scanned. Perfect for customer support or quick contact options.
Q:
What's the maximum text length for QR codes?
QR codes can technically hold up to 4,296 alphanumeric characters, but for best scanning reliability, keep it under 500 characters. Shorter content = faster scans and better error correction. For long text, consider using a URL shortener first.
Q:
Will my QR codes expire?
Never! These are static QR codes that contain the actual data (not a redirect link). They will work forever, even if Tool Studio goes offline. However, if you encode a URL, that URL must remain active for the QR to be useful.
Q:
Can I use these QR codes commercially?
Absolutely! The QR codes you generate are yours to use freely for any personal or commercial purpose without restrictions. Print them on products, business cards, marketing materials, or anywhere else you need.
Q:
Why isn't my QR code scanning?
Common issues: 1) QR code is too small - try a larger size, 2) Poor print quality - ensure high resolution and contrast, 3) Damaged or distorted QR - maintain quiet zone (white border), 4) Very long text - use error correction by keeping content short, 5) Poor lighting - scan in well-lit area.
