After saving a document, spreadsheet, or presentation which contains an image, a loss of image quality such as blur may occur.

It is not possible to recover pictures that have already been compressed.
For future saves, compression can be disabled on a per-file basis using the following steps:
You can also modify the following registry setting to prevent basic compression from occurring by default.
Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.
