When you send a message that exceeds the message size limit for either your or the recipient's mail server, the message will be returned to you and not delivered. This is often called a "bounced" message. Optimizing the size of pictures and attachments for email helps to avoid exceeding the maximum message size limits associated with most e-mail accounts. This wikiHow article teaches you how to compress images and include them as an attachment to an e-mail message

Things You Should Know

  • Lots of online websites offer to resize your pictures, but you can also use built-in tools like Preview and Paint on your Windows or Mac computers.
  • Resize a picture in Outlook by changing the values in "Crop" or dragging and dropping the handles on the picture.
  • Alternatively, Outlook will automatically resize your image if you attach it as a file instead of inserting a picture and select "Resize large images when I send this message" in "File."

    Click the envelope with the plus sign next to "New Email."
    • Use this method if you have Outlook on your phone or on your computer, and you'll be able to resize the image before sending it.
    • If you instead click Attach File and select your picture, you can set Outlook to automatically resize the picture. To do this after you attach a file, go to File and select Resize large images when I send this message.

    You'll see your picture get smaller and larger as you click the arrows.
    • By default, the original aspect ratio will remain, so when you make the picture small, it will not be distorted.
    • If you want to set the height and width sizes yourself and change the aspect ratio, click the small arrow pointing away from "Crop" to open a pop-up window with layout settings.
    • If you don't have the Outlook window enlarged to fit your screen, you won't see the Up and Down arrows next to "Crop" so you can change the image size. Instead, click the small arrow next to "Crop" and change the height and width there.
    • You can also use the points on the image to drag and drop and make it smaller.

    Gmail has some limited options for resizing images. These features are only available in the desktop browser version of Gmail. To resize a picture in Gmail, start composing an email , then click the Insert photo button at the bottom of the message window to select and insert an image. Once the image is inserted:
    • Click on it to select it. Several formatting options will appear under the image.
    • Choose from Small , Best Fit , or Original Size to change the size of the image.
    • Best Fit will be selected by default, which means Gmail may automatically shrink your pictures for you if they are very large.
    • If you try to send images that are over the attachment size limit, Gmail will put into a Google Drive folder for you. The recipient will have to click the link to see them.

    • Once you insert the image, click the Image Size dropdown in the top right corner of the message window.
    • You can select from Small , Medium , Large , or Actual Size . Actual Size is selected by default.
