Blurry QR Codes

QR codes are everywhere these days, taking us to websites, menus, and even hidden discounts. But what happens when the code itself becomes a mystery? A blurry QR code is frustrating for both users and creators. 

This is why we came up with this guide to help you create the perfect QR codes for your brand or business. Stick with us.

What is a blurry QR code?

A blurry QR code is a QR code that appears hazy or lacks sharpness, making it difficult for a QR code reader app to scan and interpret the information encoded within it.

Why is the QR code blurry? What’s the solution?

Blurry QR codes can occur because of multiple reasons, some of the following are. 

1. Inaccurate QR code size or file format

The size and file format of a QR code plays an important role in its clarity. Enlarging a QR code beyond its optimal size or saving it in a low-resolution format can lead to pixelation and blurriness, making successful scans a problem.

Solution: Generate the QR code at the recommended size using a reputable https://replug.io/qr-code-generatorQR code generator. Save it in a high-resolution format like SVG or PNG.

2. Color or contrast concerns

QR codes rely on the stark contrast between dark and light elements to function effectively. Using colors that blend or lack sufficient contrast can result in a blurry appearance, making it difficult for scanning devices to interpret the code accurately.

Solution: Ensure a clear contrast between the foreground (black squares) and background (white space) of the QR code.

3. Your QR code has expired

One of the primary reasons for encountering a blurry QR code is its expiration. Just like perishable goods, these codes come with an expiry date. If not updated or renewed, the information encoded in the code might become inaccessible, leading to blurry scans.

Solution: Use an advanced QR code generator, that offers continuous monitoring and alerts for potential issues.

4. Too many patterns or images

Adding unnecessary patterns or images to a QR code design might seem aesthetically pleasing, but it can also interfere with its readability. Excessive visual elements can cause distortion and blur, making it challenging for scanning devices to decipher the code.

QR Codes

Solution: Keep QR code designs simple and minimalistic. 

5. Broken links in the background

QR codes leading users to broken or non-existent web pages as a result of URL errors or website malfunctions can be a significant issue. These broken links not only frustrate users but also erode trust in QR code campaigns, ultimately leading to subpar user experiences and missed opportunities.

Solution: Check for any broken lines or patterns in the background of the QR code before publishing it. 

6. Not testing out your QR code

Before deploying a QR code, it’s a must to test its functionality across various devices and scanning apps. Failure to conduct thorough testing can lead to unforeseen issues, including blurry scans caused by compatibility issues or technical glitches.

Solution: Generate the QR code at the recommended size using a reputable QR code generator. Save it in a high-resolution format like SVG or PNG.

7. Website compression

If the QR code directs users to a website, website compression techniques can impact the clarity of the code. Compressed images or graphics on the website may not render well when encoded into the QR code, leading to blurriness upon scanning.

Solution: Optimize website content and images to reduce compression effects. Avoid using heavily compressed images or graphics on the website linked to the QR code.
