After downloading photos they stay in mb so they are hard to compress for email

    1. Open the photo in Paint

    Right-click the downloaded photo, select Open with → Paint.

    1. Resize the image

    Click Resize in the toolbar. Select Pixels and reduce the horizontal size to around 1200 pixels. Keep the aspect ratio enabled.

    1. Save as JPEG

    Choose File → Save as → JPEG picture. Save it under a new name so you retain the original.

    The resulting photo will often be much smaller and easier to attach to an email.

    Downloading a photo does not automatically convert it from MB to KB; to make it smaller for email, reduce its resolution before sending or use Outlook’s built-in image resizing where available.

    If you use classic Outlook

    1. Create an email and attach the photos.
    2. Select File > Info.
    3. Under Image Attachments, select Resize large images when I send this message.
    4. Return to the message and select Send.

    Classic Outlook will resize the attached images when sending them, reducing their file size. ^1^

    To create smaller copies before attaching them

    If Microsoft Word, Excel, or PowerPoint is installed:

    1. Insert the photo into a blank document.
    2. Select the photo.
    3. Open Picture Format > Compress Pictures.
    4. Choose E-mail resolution, and then select OK.
    5. Right-click the compressed picture and select Save as Picture.
    6. Give it a new name so that the original full-quality photo is preserved.

    The E-mail compression setting reduces the photo’s resolution and file size. Compression can reduce visible detail, so keep the original photo as a backup. ^2^ Saving a selected photo as a separate file is supported in Word, Excel, PowerPoint, and Outlook. ^3^

    If you use new Outlook or Outlook.com

    New Outlook can make a picture look smaller inside the message, but that does not reduce the picture’s file size. Instead:

    • Compress the image before attaching it using the method above, or
    • Upload the original to OneDrive and email a sharing link.

    Microsoft documents file compression and cloud-sharing links as the available large-file options in new Outlook and Outlook.com. ^1^

    MB and KB are simply different measurements of file size: a photo displayed in MB is larger than one displayed in KB. The home computer may be using an email or photo application that automatically resizes images, rather than the download itself performing the conversion.
