JPEG is one of the most widely used image file formats, mainly known for its compatibility across different smartphones, digital cameras, websites, and social media platforms. However, sometimes you may encounter instances when your JPEG images suddenly turn pixelated or blurry. Usually, pixelation or blurriness in your photos occurs due to repeated editing, resizing, compression, or improper storage. If you’re having JPEG photos that appear pixelated or have lost their sharpness, don’t worry!
Fortunately, there are several JPEG photo repair methods available online that you can try to repair and restore your original JPEG photos. In this guide, we’ll explore different methods on how to fix JPEG images that turned pixelated or blurry. Just go with these JPEG repair methods one by one to fix or improve your JPEG images effectively.
Why Do JPEG Photos Become Pixelated or Blurry?
Before jumping into different photo repair methods to fix your JPEG photos, try understanding why they lose clarity. Some main reasons include:
- Lossy Compression: JPEG uses lossy compression, which means some image data is permanently discarded to reduce file size. Every time you edit and re-save a JPEG file, it loses additional quality.
- Low Resolution: If an image has low resolution (small dimensions in pixels), then enlarging it stretches its original capacity. This causes visible pixelation.
- Excessive Resizing: Repeated resizing—especially enlarging—can make your JPEG image appear distorted and unclear.
- Over-Compression: Sharing photos via Social media apps and messaging platforms compresses them heavily. This can reduce sharpness and introduce artefacts in your JPEG photos.
Quick Methods to Fix Pixelated or Blurry JPEG Images
Here are some quick and effective photo repair methods that you can try to repair your JPEG images, which are pixelated or blurry:
Method 01: Configure Image Resolution Properly
Your JPEG photo may appear pixelated if it was excessively enlarged. In such cases, resizing alone won’t magically restore lost detail. However, you can use advanced tools like Photoshop, AI upscaling programs, etc., to improve enlargement quality.
If you’re resizing the image in Photoshop, always use the Image Size option and choose an appropriate resampling method, such as Preserve Details 2.0 for enlargement. Also, avoid increasing the size beyond the original resolution, as this causes pixelation.
Method 02: Fix JPEG Photos Using Photoshop
Adobe Photoshop is a powerful and robust photo editing software which can help you repair damaged JPEG photos in multiple ways. Its smart sharpen feature gives better control than basic sharpening. To fix your photos, you have to:
- Firstly, open the JPEG photo that you need to fix in Photoshop.
- Now, duplicate the layer using Ctrl + J.
- Go to Filter > Sharpen > Smart Sharpen.
- You can configure and adjust:
- Amount: 100–200%
- Radius: 1–3 pixels
- Reduce Noise: 10–20%
- Change “Remove” to Lens Blur for better results.
- Click OK to save the changes.
