Why do images lose quality?
An image loses the quality the moment it is captured, rendered and saved into your phone or camera’s memory as a JPEG file. When an image is saved as a JPEG, it is compressed. This means that part of the original information is forever lost. This is why JPEG images are so fragile and easily break up if over-edited.
Does JPEG reduce quality?
In theory, this is absolutely true. Every time a JPEG image is saved, compression algorithms are run to reduce the file size. This means that some data is lost every time you make a change to the photo and save it. Even zoomed in to 100\%, you can see that there is no difference in the quality of the photos.
Can photos lose quality?
The short answer to your question: Yes, you will lose image quality. If you resize your images down to a smaller size, and then size back up again, your image will be a lot less clear. When you resize the image back to the original size, you won’t get the original image back.

Does JPEG compression affect image quality?
While JPEG compression can help you greatly reduce the size of an image file, it can also compromise the quality of an image – and if you aren’t careful, there may not be any recovery. Each pixel has its own color value, and the larger the image, the more pixels. The more pixels, the larger the resulting file will be.
