Usage tips
Whether it's a gateway to a portfolio, a video, or a menu, the QR code has become a discreet yet powerful link between the physical and digital worlds. Now, it doesn't just transmit information: it can also convey a brand image, an intention, or an atmosphere. Thanks to intuitive tools, it's easy to customize its appearance and role.
Add your visual touch
Gone are the soulless black and white squares. Today, a QR can adopt a project's colors, be enhanced with a logo, or adapt to a visual background. This allows it to blend harmoniously into printed materials, presentations, stories, or packaging without breaking the overall aesthetic. A neat design also makes people want to scan it.
Play with visual codes
You don't need to be a designer to create a QR code that's both elegant and readable. Qreek offers an intuitive interface designed for efficiency: live preview, accessible visual settings, customization of shapes, colors, and logo integration. A few clicks are enough to achieve a professional result, without sacrificing clarity or graphic consistency. It's simple, fast, and above all, accessible to all levels.
Contextualize to convince better
Before distributing a QR, test it on different media. Contrast, size, lighting environment: all these factors influence the ability to scan quickly. High-definition export is also an asset if you plan professional printing.
A QR is more effective when accompanied by a clear indication: 'See the demo', 'Access the menu', 'Discover my work'. This creates an explicit bridge between the scanned object and the expected information, strengthening trust and engagement.
Summary:
The QR code is no longer just a utility tool. When well designed, it becomes a full-fledged design element, capable of attracting attention, guiding an action, or embodying an identity. Colors, shape, positioning, associated message: every detail counts.
