Custom QR code with logo: how to design a branded QR code without losing scannability.
A custom QR code with logo is a QR code that incorporates a brand’s logo at its center while remaining scannable. This design requires balancing visual branding with technical constraints like error correction and color contrast. Dynamic QR codes, which use short URLs and redirects, allow users to update the destination without changing the printed code. This guide covers the essentials of designing branded QR codes that work reliably and explains how dynamic QR codes function under the hood.
What is a dynamic QR code?
A dynamic QR code is a type of QR code that does not directly encode the final destination URL. Instead, it contains a short URL pointing to a redirect service.
When scanned, the QR code sends the user to a short URL, which then redirects them to the actual destination. This allows the destination to be changed anytime without altering the printed QR code itself.
How dynamic QR codes differ from static QR codes.
Static QR codes encode the full destination URL directly into the code. Once printed, the destination cannot be changed without generating a new QR code.
Dynamic QR codes encode a short URL linked to a redirect server. This indirection enables updating the final destination on the server side without reprinting the QR code.
When does the dynamic property pay off?
Dynamic QR codes are useful in printed materials like flyers, restaurant menus, packaging, and signage where reprinting is costly or impractical.
They are ideal when you need to update URLs frequently, such as changing a promotion link or fixing a broken page without wasting printed assets.
Trade-offs of dynamic QR codes.
Dynamic QR codes depend on the redirect service being available. If the service goes down, the QR code becomes unusable.
They add a small scan-time delay due to the redirect lookup, which may affect user experience slightly compared to static codes.
How the redirect works under the hood.
The QR code encodes a short URL pointing to a redirect server.
When scanned, the user’s device requests the short URL. The server looks up the associated destination URL and responds with a 301 or 302 HTTP redirect.
The device then loads the final destination URL, completing the process.
Designing a custom QR code with a logo without breaking scannability.
The key to adding a logo is using error correction, which allows the QR code to recover data from damaged or obscured areas.
Using H-level error correction (the highest standard level) lets you safely cover up to about 30% of the QR code area with a logo.
Color contrast is critical: the QR code modules (usually black) must contrast sharply with the background (usually white). Avoid low contrast color combinations.
Use SVG file format for the QR code to ensure sharp edges and scalability, especially important when printing at various sizes. PNG is acceptable but less flexible.
How KaiQR fits in.
KaiQR offers dynamic QR codes with a free tier that supports basic destination editing and unlimited scans.
Paid plans add features like custom branding, click analytics, and team collaboration.
KaiQR’s platform lets you upload a logo and customize your QR codes while maintaining scan reliability through proper error correction settings.
The redirect service is reliable and designed for long-term use, but like all dynamic QR providers, it depends on continued service availability.
Frequently asked questions
What is the maximum logo size allowed in a QR code?
The maximum logo size generally should not exceed 30% of the QR code area when using H-level error correction. Larger logos risk making the QR code unscannable.
Can I use any colors for my custom QR code with logo?
You need high contrast between the QR code modules and the background. Dark modules on a light background work best. Avoid colors that reduce contrast or blend together.
Why is SVG preferred over PNG for QR codes?
SVG is a vector format that scales without losing quality, ensuring sharp edges on any size print. PNG is raster-based and can become blurry or pixelated when resized.
What happens if the dynamic QR code redirect service shuts down?
If the redirect service goes offline, the dynamic QR code will stop working since the short URL cannot resolve to the destination. It’s important to choose a reliable provider.
