The image content in a file can significantly change the size of the document. If there are too many images in a document, it is likely to be of a significant size. For this reason, in MS Office, images are compressed by default. They are compressed to 220 ppi. There are options to further reduce them to 150 dpi or 96 dpi. This is useful in PowerPoint documents, as they are likely to have a lot of images. Even for large files, compression saves a lot of storage space. For sending as e-mail attachments and when downloading, it is recommended that you have smaller files. So even if the image quality is a bit compromised, there won't be any delay in loading the images. But if the whole document contains few images, it's fine that they are high resolution. Since the images are compressed in Office by default, you will need to manually change the quality. Follow the steps below to avoid such compressed images.

Open the MS Office file you want. Here the example will be shown with an Excel spreadsheet.

  • Click on New followed by Blank document.

  • Once the document is open, click archive in the upper right corner.

  • Also, click Advanced.

  • Scroll down to locate Image size and quality. Check the box corresponding to Do not compress images into files.

That is! The images would no longer be compressed.

Remember that the same procedure can be used for any MS Office file. The steps are the same. Once this is done, the changes will be reflected in every image in the file. There are also options to compress a specific image if you wish. Depending on the size and quality limits of the file, decide whether to compress or decompress it. I hope this helps!
