Is the QR code you made or found too blurry to scan with your phone? A blurry QR code can be caused by low image size, poor printing resolution, compression, or even environmental factors like rain and sun damage. This wikiHow article teaches you how to unblur a blurry QR Code and gives you tips to make crisp, clear, and sharp codes in the future.

Fixing a Blurry or Distorted QR Code

Printing errors, environmental factors, quality, and image compression all factor into why some QR codes are blurry. You can use online tools like HitPaw or software like Photoshop to sharpen images, but your best bet is to generate a new code with higher quality, correct print settings and paper, and proper design.

How to Sharpen a Blurry QR Code

There are a few simple online tools that make it easy to unblur a QR code. You'll need to have the QR code saved to your computer, phone, or tablet. Here are a few we recommend:

How to Create Clear QR Codes

A low-quality or smaller image size can result in a blurry QR code. When you're using tools like Adobe Express QR Code Generator, qrcodemonkey, Canva's QR Code Generator, or other online sites to create QR codes, make sure you're creating something with a high-quality resolution so it comes out sharp, crisp, and clean.

The foreground should be darker than the background and have strong contrast. Inverted colors will make your code unreadable. Avoid putting a lighter foreground on a dark background or making the two closely related colors, like gray code on a white background. In either case, cameras won't easily pick up the QR code. You'll miss out on that revenue or traffic since no one can access your code!

Not only do you want to check the printer settings (that it's printing in high-quality), but you also want to make sure that the paper you're using is optimal for the use. For example, you don't want to use heavily textured or patterned paper for a QR code.
If you're using a laser printer, use the best quality settings to get better results! For example, raise the print speed settings on a laser printer when color saturation is too high, and lower them when images or documents seem undersaturated or faded.
