Thanks for the reply, I am getting the mht file from the PSR.

What do you mean by improving quality? Are the images blurry, need sharpness or what? In general, you cannot improve the original image resolution, color depth etc...what do you need to do?

The image which i get from PSR and taking a screenshot using printscreen button are different. My images looks blurry and its not clear compared to the actual screenshot.

Depending on how the .mht file was created there may be alternatives. You need to give the details on how the .mht file is created.

I am running the PSR for taking system screenshots and it will save as zip file (ABC.Zip). when i extract this zip file i get the .mht file (Problem_20150317_1742.mht). This .mht file contains images and text. i need to extract those images and save in a folder. while doing this this the image looks blurry compared to manual screenshots.

I don't think it is possible,, sorry. Jpeg is a lossy compression format, it means that whenever an image is compressed, some informations in the original image are lost. You cannot recover the 'original' quality from the file.
There must be some algorithms that can act on smoothness, brightness, contrast, etc., and may result in a better sensation of quality; but that is not guaranteed, and the same algorithm could lead to an acceptable result for one image, and a non-acceptable for another one.
