Why are the photos processed by photoshop so unclear after being saved and opened?

Photos processed by photoshop become unclear after being saved for the following reasons.

Reason 1: When saving the picture, the resolution setting is too low, and the image becomes smaller, which will become blurred after saving.

Reason 2: When saving as JPEG, the value set in the file quality option is too low, which reduces the image quality and leads to blurring.

Reason 3: JPG format is a lossy compression format, which will blur the image compression after the image editing is completed.

Solution:

When saving, set a higher resolution in the image size dialog box, generally between 72dpi and 300dpi;

Set the image quality to the best when saving, and the value is set to 12.
