How to Reduce the size of picture attachments in Outlook
- Reduce the picture dimensions Digital cameras can create very large images far in excess of the dimensions that most computer monitors can display full screen. Compressing the image to a smaller width and height can greatly reduce the file size. This option is available for pictures that are attached, but not displayed within the message body.
- Compress the picture resolution By decreasing the dots per inch (DPI), file size is reduced, but the quality of the image is also impacted. Displaying images on a computer monitor requires a lower DPI than images that are printed. If the recipient doesn’t need higher quality resolutions, use a lower setting. This option is available for pictures that appear within the message body.
In all cases, the original picture file saved on your computer hard disk or memory device is not modified. Only the copy of the picture being sent is reduced in size.
Picture files attached within Outlook
When you add attachments in Outlook, you can reduce picture attachments on a per-message basis. When you choose to resize large images, any attached image is reduced to a maximum resolution of 1024×768 pixels
Note: If you embed the picture in the message body — the picture appears in the message — by using the Picture command in the Illustrations group, the image attachment resize feature is not available.
