QR Code Generator: Create Custom QR Codes in Seconds
What it is
A QR Code Generator that creates custom QR codes quickly — encode URLs, text, contact cards, Wi‑Fi credentials, payment links, and more.
Key features
- Fast creation: Generate a QR code in seconds from any input.
- Formats supported: URL, plain text, vCard, Wi‑Fi, email, SMS, phone numbers, and calendar events.
- Customization: Change colors, add logos, adjust corner styles and eyes, choose error-correction level.
- Export options: Download as PNG, SVG, PDF, or EPS for web and print.
- Error correction: Select levels (L, M, Q, H) to allow scanning even with partial damage or overlayed logos.
- Scan testing: Preview how codes scan at different sizes and distances.
- Dynamic codes (optional): Create editable/trackable short URLs behind QR codes to update destination without changing the code.
- Analytics (optional): Track scans by time, location, device, and referrer for marketing insights.
Best practices
- Use high contrast: Dark code on a light background ensures reliable scanning.
- Size appropriately: For print, keep codes at least 2 x 2 cm (0.8 x 0.8 in); increase for long distances.
- Allow quiet zone: Maintain a margin around the code equal to four modules (the small squares).
- Choose error correction based on design: Higher error correction lets you add logos but increases density.
- Test across devices: Scan with multiple phones and apps before distribution.
When to use
- Marketing materials (flyers, posters, business cards)
- Event check‑ins and ticketing
- Contact sharing (vCards)
- Wi‑Fi auto-join
- Payments and donations
- Product packaging and instructions
Limitations
- Dense data makes complex codes harder to scan at small sizes.
- Custom colors or heavy design overlays can reduce readability.
- Static codes require regeneration to change the destination unless using dynamic codes.
If you want, I can generate suggested short copy or sizes for print materials (business card, flyer, poster).
