Last Updated: November 2, 2025

Welcome to the QR Master FAQ section. Here you’ll find answers to the most common questions about generating, customizing, and using QR codes safely. We designed this page to help users, developers, and businesses make the most out of our platform — efficiently, securely, and in full compliance with Google AdSense and global privacy regulations.

General Questions

What is QR Master?

QR Master is an online QR-code generator that allows you to create, customize, and manage professional-grade QR codes for personal or business use. Our platform supports multiple QR types — links, Wi-Fi, text, vCards, payments, and more — with full AdSense policy compliance and privacy protection.

Do I need to register to use QR Master?

No registration is required to generate basic QR codes. However, creating an account allows you to save your designs, manage campaigns, and access advanced analytics features like scan tracking and dynamic QR editing.

Is QR Master free?

Yes. Most core features are completely free. Premium or enterprise plans may include advanced customization, dynamic QR codes, and branded analytics dashboards for professional users.

How do I generate a QR code?

Simply choose a QR type (for example, Website URL or Wi-Fi), fill in the required fields, customize the design if needed, and click “Generate.” You can then download your code in PNG, SVG, or PDF formats for print or digital use.

Technical and Design Questions

Can I customize the appearance of my QR codes?

Absolutely. You can change colors, shapes, add logos, or use templates to match your brand identity. QR Master ensures all designs remain fully scannable regardless of customization level.

What file formats are supported for download?

You can download QR codes in PNG, SVG, and PDF formats. All exports are high-resolution and ready for print or digital media.

Do QR codes expire?

Static QR codes never expire — they’ll work indefinitely as long as the encoded content remains accessible. Dynamic codes can be updated or deactivated manually at any time through your dashboard.

What’s the difference between static and dynamic QR codes?

Static QR Codes contain fixed information that cannot be changed once generated. Dynamic QR Codes link to a short URL hosted by QR Master, allowing you to update destinations, track scans, and analyze engagement without reprinting your code.

How large should a QR code be for printing?

For best results, keep the code size at least 2 × 2 cm (≈ 0.8 inches) for short URLs, and larger for complex or logo-rich designs. Maintain high contrast between foreground and background colors for reliable scanning.

Security and Privacy

Are QR Master codes safe?

Yes. All QR codes are generated using secure HTTPS links. We never inject tracking pixels or hidden scripts. You control your data entirely, and all generated links comply with Google AdSense and privacy standards.

Can someone hack a QR code?

The code itself cannot be hacked, but a malicious actor could replace a printed code with a fake one. Always verify the source before scanning and use trusted generators like QR Master to ensure link safety.

Does QR Master collect user data?

We collect only minimal technical data required for service functionality (e.g., anonymous scan counts for dynamic QR codes). We never sell or share personal information and comply with GDPR, CCPA, and AdSense policies.

How can I make my QR codes more secure?

Use HTTPS links, avoid embedding personal data directly, and enable password protection or expiration where possible. QR Master offers encrypted dynamic QR codes for additional safety.

Business and Marketing

Can I use QR codes for advertising campaigns?

Yes, but all campaigns must comply with advertising and AdSense content policies. Avoid linking to deceptive, adult, or restricted content. QR Master automatically validates URLs to help ensure compliance.

Can I track scans or engagement metrics?

Dynamic QR codes allow you to view statistics such as scan counts, location, and time data. Analytics are anonymized and intended to improve performance tracking while maintaining user privacy.

How can QR codes improve my marketing results?

They simplify engagement by turning offline materials into instant digital interactions. From flyers and posters to business cards and packaging, QR codes boost conversions and bridge the gap between print and web.

Technical Support

My QR code doesn’t scan — what should I do?

Check contrast, size, and quiet-zone spacing around the code. Avoid blurry prints or overly dark backgrounds. You can also test on multiple devices or regenerate with higher resolution from your QR Master dashboard.

Can I integrate QR Master into my mobile app or website?

Yes. We provide a developer-friendly API and SDKs that allow you to generate and manage QR codes programmatically. Documentation and examples are available in our developer portal.
