Send attachments with your Gmail message

You can add attachments, like files, videos, and photos in your emails. If you want to send large files that are over the attachment size, like videos, you can use Google Drive. 

Attach a file

  1. Open Gmail.
  2. Click Compose.
  3. Click Attach Attach.
  4. Choose the files you want to upload.
  5. Click Open.

Tip: You can also add an image by dragging and dropping it into the compose window.

Remove an attachment

After you add an attachment, you can remove it. To the right of the attachment name, click Close Close.

Attachment size limit

You can send up to 25 MB in attachments. If you have more than one attachment, they can't add up to more than 25 MB.

If your file is greater than 25 MB, Gmail automatically adds a Google Drive link in the email instead of including it as an attachment. The person you send the file to can download it so they'll have access to it even if you remove it from Google Drive. Learn more about Google Drive attachment sharing settings.

Attachments won't upload

If you get an error message while adding an attachment, try these steps:

  1. Make sure you're using a supported browser.
  2. Try adding the attachment in another browser.
  3. If you have a web browser proxy set up, try disabling it.

Troubleshoot problems

"Attachments might be unavailable"

If you see "Attachments might be unavailable," your network administrator or Internet provider might block "mail-attachment.googleusercontent.com," the domain Google uses to host attachments. Contact your Internet service provider to troubleshoot.

"Blocked for security reasons"

To prevent viruses, Gmail doesn't let you attach executable files, like files ending in .exe. If you try to attach an executable file, you'll see the message "Blocked for security reasons."
