Free QR Code Generator by HeYHLo lets you create high-quality QR codes for URLs, contact cards, Wi-Fi access, PDF downloads, text, email, and more — instantly and for free. No signup, no software, and full customization options for size, color, and error correction.
What Is a QR Code Generator?
A QR Code Generator is an online tool that converts information (such as website links, contact information, or plain text) into a two-dimensional barcode known as a QR code. QR codes are easily scanned by smartphone cameras and QR readers, instantly delivering the encoded content to users. Because QR codes are compact and scannable, they’re widely used in marketing, payments, product packaging, events, and more.
How the Free QR Code Generator Works
Our tool creates both static and dynamic QR codes quickly using a few straightforward steps:
- Select the QR code type (URL, vCard, Wi-Fi, Text, Email, Phone, PDF, or Dynamic link).
- Enter the content you want to encode (for example a URL or contact details).
- Customize appearance — choose size, color, background, logo, and error correction level.
- Generate the code and preview it on-screen.
- Download the QR code as PNG, SVG, or PDF for print and web use.
- Optional for Dynamic codes: update the destination later without changing the printed QR code.
The entire process runs in your browser and takes a few seconds.

Customization Options — Make QR Codes That Match Your Brand
Brand-consistent QR codes increase scan rates. Our generator offers:
- Colors: Foreground and background color pickers (use brand hex codes).
- Logo & Icon: Add your logo at the QR center (auto-resizes, keeps scannability).
- Shape Variations: Rounded modules, square modules, or eye-shapes to match visual identity.
- Frames & Call-to-Action: Add a frame with text like “Scan to visit” to improve engagement.
- High Error Correction: Increase to H to allow for logo overlays and partial damage.
Careful customization improves aesthetics while maintaining scanning reliability.
Common Use Cases for QR Codes
QR codes are versatile. Here are popular ways businesses and creators use them:
| Use Case | Example |
|---|---|
| Marketing & Advertising | Poster/print ad linking to promotional landing page |
| Contact Sharing | vCard QR on business cards — tap to save contact |
| Wi-Fi Access | Guest Wi-Fi QR on cafe tables — easy connection |
| Payments | Instant payment QR for POS or donation drives |
| Event Check-in | Tickets with QR codes scanned at the entrance |
| Product Packaging | Link to instructions, warranty registration, or video demo |
Why Businesses Should Use QR Codes
QR codes bridge offline and online experiences. They:
- Make information instantly accessible via mobile devices.
- Reduce friction — no typing long URLs or details.
- Support contactless interactions — valuable for hygiene-conscious consumers.
- Enable quick conversions from print to web — increasing campaign effectiveness.
- Allow for tracking and analytics when dynamic codes are used.
How to Create a High-Quality QR Code — Step-by-Step
- Choose the right type: URL for websites, vCard for contacts, Wi-Fi for access, etc.
- Use short URLs: Shorter destinations create simpler QR patterns and scan more reliably.
- Select appropriate error correction: Choose H if adding a logo.
- Keep contrast high: Use dark foreground and light background for easy scanning.
- Test on multiple devices: Scan with different phones and apps before printing.
- Use vector formats for print: Export SVG or PDF to maintain crispness at any scale.
Following these steps reduces scan failures and improves user experience.
QR Code Size & Print Guidelines
Optimize QR size for the distance at which users will scan:
- Small items (business cards): Minimum 2 cm × 2 cm (0.8 in) — test before print.
- Posters & banners: 10–20 cm depending on expected scan distance.
- Packaging: Ensure quiet zones (margin) around the code — at least 4 modules width.
Always print a test copy and scan it at intended distance to verify readability.
Security & Privacy Considerations
QR codes are a convenience and can carry risks if misused. Keep these tips in mind:
- Validate destinations: Warn users if the QR opens external pages — use HTTPS links.
- Avoid embedding sensitive data: Don’t put passwords or personal data directly into static QR codes unless encrypted.
- Use dynamic redirect services carefully: Ensure you trust the provider and monitor click activity.
- Educate users: Label codes clearly (e.g., “Scan to view menu”) so users know what to expect.
Examples — QR Code Types & Sample Use
| QR Type | Example Content | Typical Use |

FAQ (Frequently Asked Questions)
1. Is the Free QR Code Generator really free?
Yes — you can generate static QR codes for free without signing up. Some advanced features (like analytics or API/batch) may be part of premium or enterprise options.
2. What formats can I download?
Download QR codes as PNG (raster), SVG (vector), or PDF for the best print quality.
3. Can I update the destination after printing?
Only with dynamic QR codes. Dynamic codes point to a short redirect URL which you can change later in the control panel.
4. Will adding a logo break the QR code?
Not if you use sufficient error correction (Q or H). Always test on multiple phones before finalizing printed materials.
5. Are QR codes safe to use?
QR codes themselves are safe, but scanning unknown codes can be risky if they lead to malicious websites. Use HTTPS and label codes clearly to build trust.
6. Do QR codes work offline?
Static QR codes that encode text or contact information work offline. Codes that link to online resources require internet access on the scanning device.
