FAQ

Q: What types of data can I encode in a QR code?

A: You can encode almost anything: website URLs, plain text, contact information (vCard), WiFi credentials, email addresses, phone numbers, SMS messages, geographic coordinates, and more. The maximum length is 2,000 characters.

Q: What size should I make my QR code?

A: It depends on your use case: - Digital displays: 200-400px is sufficient - Printed materials: 300-600px for crisp results - Business cards: 200-300px - Posters/signage: 500-1000px - Billboards: 1000px+

The general rule is: the further away people will scan from, the larger the QR code should be.

Q: What error correction level should I choose?

A: Use Medium (M) for most applications. It provides a good balance between data capacity and error tolerance. Use High (H) if: - The QR code might get damaged or dirty - You're placing a logo in the center - The code will be on a textured surface - Lighting conditions might be poor

Q: Can I put my logo in the QR code?

A: Yes! Pro users can add a center logo. Keep these tips in mind: - Logo should be small (no more than 20% of QR code area) - Use high error correction level (Q or H) - Ensure the logo doesn't cover critical parts - Test thoroughly before mass printing

Q: Will my QR code expire?

A: The QR code itself never expires - it's just an image. However, if it points to a URL, make sure that URL remains active. Consider using a URL shortener with redirect capability if you might need to change the destination later.

Q: Why isn't my QR code scanning?

A: Common issues: - Too small: Make it larger - Low contrast: Ensure dark on light background - Damaged: Regenerate with higher error correction - Too complex: Shorten the URL or text - Poor lighting: Test in different lighting conditions - Camera focus: Hold phone steady and ensure QR code is in focus

Q: Can I use QR codes for commercial purposes?

A: Yes! QR codes are not patented and can be used freely for any purpose, including commercial use. However, ensure the content you're linking to complies with relevant laws and regulations.

Q: What's the difference between PNG, SVG, and JPEG formats?

A: - PNG: Lossless compression, supports transparency, best for most uses - SVG: Vector format, scales infinitely, perfect for large prints - JPEG: Lossy compression, smaller files, but can reduce scanning reliability

Q: How do I create a WiFi QR code?

A: Use this format in the text field: WIFI:T:WPA;S:YourNetworkName;P:YourPassword;; Replace WPA with your security type (WPA, WEP, or leave blank for open networks), YourNetworkName with your SSID, and YourPassword with your WiFi password.

Q: Can I track how many times my QR code is scanned?

A: QR codes themselves don't have tracking built-in. To track scans, use a URL shortener with analytics (like Bitly) in your QR code, or link to a page with analytics installed.

Troubleshooting

QR Code Won't Scan

1. Increase Size: Try generating at a larger size (500px+)
2. Higher Error Correction: Switch to Q or H level
3. Simplify Content: Shorten URLs or reduce text
4. Check Contrast: Ensure dark foreground on light background
5. Test Different Devices: Some cameras perform better than others

Poor Print Quality

1. Use SVG Format: Vector format scales without quality loss
2. Increase Size: Generate at final print size or larger
3. High Resolution: Use 600px minimum for print
4. Test Print: Always print a test copy and scan before mass production

File Too Large

1. Reduce Size: 300-400px is sufficient for most uses
2. Use PNG: More efficient than JPEG for QR codes
3. Optimize: Use online image optimizers without losing quality

Bulk Processing Fails

1. Check CSV Format: Ensure headers match template exactly
2. Row Limit: Stay within your tier's row limit
3. Valid Data: Ensure all URLs and text are properly formatted
4. File Encoding: Save CSV as UTF-8 encoding

Best Practices

Design

- Maintain minimum 10% quiet zone (white space) around QR code - Use high contrast colors (black on white is best) - Test on multiple devices before finalizing - Consider placement and viewing angle

Technical

- Use error correction level Q or H when adding logos - Generate at final size or larger - Test scanning distance in real conditions - Save master files in SVG for future scaling

Marketing

- Include clear call-to-action ("Scan to visit website") - Provide alternative access method (short URL) - Track analytics on destination URLs - Update content without regenerating QR code using redirect URLs

Printing

- Use vector formats (SVG) for professional printing - Minimum 2cm x 2cm for handheld scanning - Test print and scan before mass production - Ensure printing process preserves sharp edges
