How to Test a QR Code Online

QR codes are widely used in marketing, business, and daily life. But before distributing them in print materials, it’s crucial to test them. One non-working code on a thousand flyers means wasted budget, and the effect of a digital business card with a QR code drops to zero.

In this article, you'll learn how to test a QR code online, which parameters affect its readability, and which mistakes to avoid.

Generating a Test QR Code

Before testing a QR code, you need to generate it. You can create either a static or a dynamic QR code:

  • A static QR code is free but cannot be edited after printing.

  • A dynamic QR code is paid, but it allows you to change the content, track scans, and gather analytics.

To try it out, visit the QR TIGER platform, select the desired function (link, file, menu, etc.), customize the appearance, and get a test code.

What to Check Before Testing

Before starting the testing process, make sure your QR code meets the following criteria:

  • High contrast between the code and the background (dark code on a light background)

  • Sufficient size, especially if the QR code will be placed at a distance

  • Correct link or file embedded in the code

  • Minimal content — do not overload a static code with data

  • Compatibility with various devices and platforms

How to Scan a QR Code

Most modern smartphones can scan QR codes directly through the camera. You can also use social media apps (Instagram, Snapchat) or dedicated scanner apps.

Instructions:

  1. Open your camera or a scanning app

  2. Point it at the QR code

  3. After 2–3 seconds, the link or content will open

How to Test a QR Code Online

Before mass printing or deployment, test your QR code in various conditions.

Check Lighting Conditions

Test scanning:

  • In low light

  • In bright light

  • During the day and at night

If the QR code is difficult to read, increase the color contrast.

Test on Different Devices

The code should scan on both Android and iOS. Sometimes it works on one device but fails on another — so test it on multiple gadgets.

Check the Scanning Distance

Determine from what distance the QR code will be scanned:

  • If it’s placed on a business card — a small size will work

  • If it’s on a banner — increase the size

Check Internet Access

A dynamic QR code requires an internet connection to work. Make sure there is coverage in the chosen location. A static code works even without internet access.

Best Practices for Creating a Scannable QR Code

  • Don’t change colors drastically — a light background with a dark code is best

  • Avoid pixelation — don’t overload a static QR code with too much data

  • Don’t over-design — minimalist designs improve readability

Before printing or distributing a QR code, always test it. This helps avoid technical issues and saves resources. Follow these simple tips, and your QR codes will work reliably and effectively.
