How to Fix JPEG Images That Turned Pixelated or Blurry?

This makes it best for cameras, phones, websites and social media. However, sometimes your JPEG pictures can become fuzzy or blurry. There are several reasons, ranging from excessive compression to corrupted file itself etc., why your image may appear pixelated or blurry.

Fortunately, there are several ways to restore images using some online photo repair to fix your broken photos. In this article, we will talk about the reasons for which JPEG pictures become either pixelated or blurry and suggest how to solve the problem. Let’s begin!

Understanding Pixelation and Blur in JPEG Images

Before applying any photo repair workaround to fix your blurry JPEG pictures, you need to understand the meaning of pixelation and blur.

Pixelation

Pixelation is when you can see the individual pixels of your picture, and this makes it look chunky or rough. This happens when:

• A low-resolution image is enlarged beyond its original size.
• Excessive JPEG compression reduces image details.
• The image is repeatedly saved in JPEG format.
• The original image has insufficient pixel data.

 

Blurriness

Any photo is called blurry when its sharpness and detail are lost. Common causes include:

• Camera shake during photography.
• Incorrect focus settings.
• Motion blur caused by moving subjects.
• Image resizing and compression.
• Corruption or degradation during file transfer.

 

Common Reasons for Pixelated or Blurry JPEG Images

Identifying the exact cause of why you are getting pixelated or blurry images can help you to know what kind of photo repair workarounds you need to try. Some common causes include:

Excessive Compression

JPEG images use the lossy compression technique to reduce the image file size. Over-compressing your photo would result in loss of some image details and creation of artefacts.

Low Image Resolution

Using a low-quality camera to take photos can result in pictures that look pixelated or blurry. Any enlargement of such photos will lead to pixelation due to the lack of enough information.

Over Editing and Saving

Each time you edit or save JPEG image, some data is lost. With time, it becomes easy to notice the poor quality of the image.

Improper Resizing

Overstretching of the image will lead to blurriness of the edges and visibility of pixels.

File Corruption

Some other issues, like storage device problems, interrupted transfers, malware attacks, or software errors, are also one of the main reasons for damaged image files, which lead to visual distortions.

 

Quick Methods to Fix Pixelated or Blurry JPEG Images

Now that you’re familiar with the reasons for your damaged JPEG images, it’s time to apply adequate photo repair methods. Here are quick and easy JPEG repair fixes that can help you to repair blurry photos:

Method 01: Reduce Noise and Compression Artefacts

Excessive compression of your JPEG photos sometimes introduces artefacts that resemble blocky patterns or grain. In such a case, follow the below steps to reduce noise in your images:

• Firstly, open your pixelated or blurry JPEG image in a photo editing software.
• Now, use the noise reduction tool.
• Adjust luminance and colour noise settings.
• Once done, check if pixelation is fixed in your photo.

Noise reduction can improve overall image appearance while minimising pixelation effects.

 

Method 02: Fix Blurry Photos Using Deblurring Features

Several third-party programs like Adobe Photoshop, Lightroom, Remini and others are available and known for inbuilt deblurring features which you can use to solve issues of motion blur and focus problems. To fix blurry images using Photoshop you need to:

• Launch Photoshop and open your blurry photos in it.
• Select Filter, go to Sharpen > Smart Sharpen.
• Set Remove to Lens Blur.
• Also, increase Amount and adjust Radius until the image looks sharper.
• Click OK to apply the changes.

Results depend on the severity of the blur and the amount of recoverable detail.

How to Prevent JPEG Images from Becoming Pixelated or Blurry?

Using the above-described photo repair methods to fix pixels or blurry photos is relatively simple. In addition, you can take some measures to prevent images from becoming pixelated or unclear:

• Capture the image using the highest resolution, as more the number of pixels in an image, the more the amount of information is displayed.
• Save the image in its highest quality state without performing any editing or resizing of the image. Having the best quality photo as a backup will ensure that you revert to the original image in case you fail while editing the image.
• Do not up-scale your low-resolution photos to a size bigger than the original size of the image. You will end up losing the quality of the photo if you enlarge it to a size where pixels can become visible.
• Make sure that the camera of the phone is focusing on the desired object. Some phones have tap-to-focus technology.
