Frequently Asked Questions
What is a QR code?
A QR (Quick Response) code is a two-dimensional barcode that stores data as a pattern of black and white squares. It can be scanned by smartphone cameras and QR code reader apps to quickly access the encoded information — such as opening a URL, connecting to WiFi, or saving a contact.
QR codes were invented in 1994 by Denso Wave, a Japanese automotive company, to track vehicle parts during manufacturing. Today, they're used worldwide for marketing, payments, authentication, and information sharing.
Which QR code type should I use?
Choose the type based on your content:
- URL / Text — Websites, plain text, or any alphanumeric content
- WiFi — Share network credentials without typing passwords
- vCard — Digital business cards that save directly to contacts
- Email — Pre-filled emails for quick communication
- SMS — Quick text messages with pre-filled content
- Location — GPS coordinates for map navigation
- Event — Calendar invitations that save to user's calendar
- Crypto — Cryptocurrency payment requests with wallet addresses
What does error correction mean?
Error correction allows a QR code to remain scannable even if parts of it are damaged, dirty, or obscured. The QR code standard uses Reed-Solomon error correction with four levels:
| Level | Recovery | Best For |
|---|---|---|
| L (Low) | ~7% | Clean environments, digital displays |
| M (Medium) | ~15% | General use, printed materials |
| Q (Quartile) | ~25% | Industrial environments, outdoor use |
| H (High) | ~30% | Logo embedding, harsh conditions |
Can I add my company logo to the QR code?
Yes. Upload a PNG or JPG image (under 2MB) in the Customize section. The logo is placed at the center of the QR code, and error correction is automatically set to H to compensate for the covered area.
What format should I download?
PNG Format
- Most widely supported
- Supports transparency
- Perfect for web and documents
- Lossless compression
SVG Format
- Vector graphics
- Infinite scalability
- No quality loss at any size
- Ideal for professional printing
JPG offers a smaller file size but does not support transparency. Use it for email attachments and messaging when file size matters more than quality.
Is my data safe?
Yes. All processing happens in your browser using client-side JavaScript. No data is transmitted to any server. Your WiFi passwords, contact information, cryptocurrency addresses, and other content remain on your device.
Zero Data Collection
We don't log, store, or analyze any input data.
Local Processing
All QR generation runs in your browser memory.
Open Source
Code is transparent and verifiable.
Why does my QR code not scan?
Common scanning issues and solutions:
- Low contrast — Use dark foreground on light background (or vice versa)
- Complex dot styles at small sizes — Use square dots for codes under 512px
- Logo too large — Keep logo under 20-30% of code area
- Insufficient error correction — Use level H when embedding logos
- Too much data — Reduce content length or increase QR code size
- Poor print quality — Use SVG format and print at high resolution
What is the maximum content length?
QR codes can store up to approximately 4,296 alphanumeric characters or 7,089 numeric characters. The actual limit depends on the content type and error correction level:
| Data Type | Maximum Capacity | Error Correction Impact |
|---|---|---|
| Numeric only | 7,089 characters | -30% at level H |
| Alphanumeric | 4,296 characters | -30% at level H |
| Binary/Byte | 2,953 bytes | -30% at level H |
| Kanji/Kana | 1,817 characters | -30% at level H |
A character counter below the URL/Text input shows how much capacity you've used. Keep in mind that larger QR codes with more data become more complex and may be harder to scan, especially at small sizes.
