Compress Pictures is available in the desktop Office apps, not in Microsoft 365 for the web.
To access it in Word on Windows:
- Open the document in Word desktop.
- Insert the
.JPG into the document, or select a picture already in the document.
- Select the picture.
- Go to the Picture Format tab.
- In the Adjust group, select Compress Pictures.
- If the ribbon is narrow, the button may appear as an icon without a label.
- Choose whether to apply compression only to the selected picture.
- Under Resolution, choose the resolution needed, then select OK.
Important details:
- This feature compresses pictures in a document. It is not described as a standalone JPG file resizer.
- If the Picture Format tab does not appear, the picture is not selected. Double-click the picture if needed.
- The default picture resolution in Office is 220 ppi.
- Compression can reduce image detail.
If the goal is to reduce the size of the original image file itself, one supported method is:
- Insert the JPG into Word.
- Use Picture Format > Compress Pictures.
- Save the document.
For older Picture Manager guidance, the path is similar:
- Select the picture.
- Click Picture Tools Format.
- Click Compress Pictures.
- Choose Print, Web, or E-mail.
- Click OK, then save the compressed picture.
