JPEG (Joint Photographic Experts Group) is a popular image file format used nowadays. It strikes a balance between compression and image quality, making it best for sharing and storing images. However, sometimes you may encounter situations when JPEG images get corrupted. This means when you save or edit a JPEG image, some quality is lost due to compression.

Luckily, there are several JPEG repair methods available online that you can try to repair your JPEG image file and obtain the original image. In this guide, we will explore various techniques to help you learn how to improve JPEG quality. Just go with these methods one-by-one for enhancing JPEG images.

Why JPEG Image Quality Degrades?

Before diving into JPEG repair methods to improve JPEG image quality, it’s important to understand why your image files usually get compressed or corrupted. JPEG files use a lossy compression algorithm, which reduces file size by discarding some of the image data, resulting in loss of detail and sharpness of your image.

There are many reasons for the loss in quality of JPEG images, some of them are:

• Over-compression: Saving a JPEG file at a lower quality setting increases compression and leads to artifacts and pixelation.
• Multiple edits and saves: Whenever you open, edit or save a JPEG file on your device, the image undergoes compression, which leads to cumulative loss of quality.
• Resizing: Scaling a JPEG image down and then enlarging it can cause a loss of clarity and introduce artifacts.
• Noise and artifacts: JPEG images can suffer from visible artifacts, such as blockiness or noise, due to compression.

Quick Methods to Improve JPEG Image Quality

Understanding the above-mentioned factors can help you identify the adequate JPEG repair method to enhance your image quality. In this part of the blog, we’ve enhanced various methods that can help you in obtaining your original image file:
