Feature Comparison

QRelix

Dynamic QR Codes & Real-Time Updates

Never worry about a printed QR code leading to outdated information again. QRelix creates dynamic QR codes, which means the destination link behind the code can be changed at any time from your dashboard. Update a menu, switch a promotion, or correct a link—all without touching your printed materials. This feature saves you time, money, and ensures your audience always gets the right information.

Comprehensive Real-Time Analytics

Understand your audience with detailed, real-time scan analytics. For every QR code you create, QRelix tracks key metrics like the total number of scans, the location (down to the city level), the type of device used (iOS, Android, etc.), and the exact time of each scan. This data is invaluable for measuring campaign success, understanding customer behavior, and making informed decisions to optimize your marketing efforts.

Advanced Customization & Branding

Make your QR codes an extension of your brand. QRelix offers deep customization options, allowing you to change the colors of the QR code and its background, add a central logo, and adjust the style of the code's dots. You can then export your design as a 300 DPI SVG file, which is a vector format that ensures crisp, high-quality printing on anything from small business cards to large billboards.

Mirrored QR & Password Protection

Two powerful features for control and versatility. The Mirrored QR feature lets you take any existing QR code (even one you didn't create) and "mirror" it through QRelix. This allows you to apply your own branding and tracking to it. Password Protection adds a layer of security, letting you restrict access to the QR code's content. Users must enter a password you set before they can see the linked information, perfect for exclusive offers or private documents.

What is a dynamic QR code and why is it better?

A dynamic QR code is one where the destination URL can be changed after the code is created and printed. This is far superior to a static code, which is permanently fixed. With QRelix's dynamic codes, you can correct typos, update promotions, or change linked content anytime from your online dashboard, giving you maximum flexibility and preventing wasted printed materials.

QRelix provides detailed analytics on scans, but it focuses on aggregated, anonymous data to protect user privacy.

It does not collect or display personally identifiable information like specific names or email addresses from scans.

What file format do I get for printing?

QRelix allows you to export your customized QR codes as 300 DPI SVG files. SVG is a vector format, which means it can be scaled to any size without losing quality or becoming pixelated.
