1. How do I create a QR code for free?
Use a Free QR code builder like CalculatorGrid’s tool to generate codes instantly. No signup required—just enter your URL/text, customize the design, and download.
✓ Pro Tip: Free tools often limit features; ours includes color/shape customization.
2. Can I add a logo to my QR code?
Yes! A QR code maker with logo support (like ours) lets you upload a PNG/JPG to embed in the center. Ensure the code remains scannable by testing it afterward.
✓ Best Practice: Use high-contrast logos for better scans.
3. What’s the difference between QR codes and barcodes?
Barcodes: Store limited data (numbers) horizontally (UPC/EAN).
QR codes: Store 100x more data (text, URLs) vertically + horizontally.
Our QR code & Barcode builder generates both types.
4. How can I change the color of a QR code?
With a custom QR code generator, pick any color or gradient. Avoid light colors on white backgrounds—contrast is key for scannability.
✓ Try This: Use brand colors for marketing consistency.
5. Are QR codes safe from hackers?
Most are safe, but malicious links can hide in codes. Use a trusted QR code generator and scan with a tool that previews URLs (like Google Lens).
✓ Safety Tip: Don’t scan random codes in public places.
6. Can QR codes expire?
Static QR codes (made with a basic code builder) don’t expire. Dynamic codes (from paid platforms) can be set to deactivate after a date.
7. What’s the best format to download a QR code?
PNG (for digital use) or SVG (for printing). Our QR & Bar code builder offers both + 300 DPI resolution.
✓ Pro Tip: SVG scales perfectly for billboards/business cards.
8. Why isn’t my QR code scanning?
Common fixes:
Increase size (min. 2x2 cm for print).
Improve contrast (dark-on-light works best).
Test with multiple scanners.
9. Can I make a QR code for a WiFi password?
Yes! A QR code & Bar Code builder with WiFi support generates scannable codes that auto-connect devices. No more typing long passwords.
