  2. Click Compose.
  3. At the bottom, click Attach Attach.
  4. Choose the files you want to upload.
  5. Click Open.
Tip: You can also add an image by dragging it directly into the compose window.

Remove an attachment

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

Send attachments using confidential mode

Tip: If you're using Gmail with a work or school account, contact your admin to make sure you can use confidential mode.

  2. Click Compose.
  3. Click Attach Attach.
  4. Choose the files you want to attach to your message.
  5. In the bottom right of the window, click Turn on confidential mode Turn on confidential mode.
    Tip: If you've already turned on confidential mode for an email, go to the bottom of the email, then click Edit.
  6. Set an expiration date and passcode. These settings impact both the message text and any attachments. 
    • If you choose "No SMS passcode," recipients using the Gmail app will be able to open it directly. Recipients who don't use Gmail will get emailed a passcode.
    • If you choose "SMS passcode," recipients will get a passcode by text message. Make sure you enter the recipient's phone number, not your own.

Troubleshoot problems

Attachment size limit

You can send up to 25 MB in attachments for each message. If you have more than one attachment, they can't be more than 25 MB total.

If a file is greater than 25 MB, Gmail automatically adds a Google Drive link instead of including it as an email attachment. Learn more about Google Drive attachment sharing settings.

Attachments won't upload (Desktop)

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

Attachments might be unavailable

Your network administrator or Internet provider likely blocked the domain, "mail-attachment.googleusercontent.com," which Google uses to host attachments.

For more help, contact your network administrator or internet service provider.

Blocked for security reasons

Gmail doesn't let you attach executable files, like files ending in .exe to prevent viruses.
