Email Attachment Size Restrictions in Yahoo and Gmail


Yahoo Mail and Google's Gmail share the same attachment limit of 25MB, but with the help of cloud storage, you can get around this limit and send much larger files. With a free Google Drive account on Gmail, you can attach files up to 15GB. Yahoo Mail works with Dropbox and Flickr to send files as large as can fit in your Dropbox and Flickr accounts. And with most cloud-storage services, you can create sharable links to send by email, avoiding the attachment limit entirely.

Attachment Size Limits

  • Both Gmail and Yahoo Mail have the same limit on email attachments: You can only send or receive emails up to 25MB large. This limit applies to each email individually, not each attachment -- you can send or receive three separate emails, each with a 10MB attachment, but not one email with three 10MB attachments.

    The process of encoding and sending an attachment can add to its size. According to Yahoo, you should factor in an extra third of the file's original size, so a 20MB file might not actually fit under the 25MB limit.

External Size Limits

  • Even if you keep your attachments under the Gmail or Yahoo Mail size limit, your email will bounce back if your recipient's email service has a smaller limit. If you run into trouble, try splitting up your attachments across several emails or send the files using another method.

Gmail Workaround -- Google Drive

  • To send files larger than 25MB on Gmail, insert a file with Google Drive. With a free Drive account, you can send files as large as 15GB. Paid Drive members can attach files as large as an entire terabyte. To attach files using Drive, click the Drive icon instead of the attachment icon while writing your message. Pick a file on Drive or click Upload to add a new file from your computer.

Yahoo Workarounds -- Dropbox and Flickr

  • Yahoo Mail supports attaching files of any size on Dropbox and pictures of any size from Flickr -- provided they fit in your Dropbox or Flickr storage limit. Instead of clicking the attachment icon directly, open the nearby drop-down menu and choose either Share from Dropbox or Share from Flickr to pick a file to attach. The first time you use Dropbox on Yahoo, the site asks you to sign in to your Dropbox account to link it with your Yahoo account. Yahoo owns Flickr, so you won't need to perform this process to add Flickr photos.

Other Cloud Solutions

  • If you'd prefer to use Dropbox with Gmail, Google Drive with Yahoo Mail, or use another cloud service entirely, such as Box or OneDrive, create a sharable upload link.

    Most cloud-storage services support sharable links to a file. Create a link and paste it into the body of your email to share the file, regardless of which email provider you use. For example, Gmail has no trouble sending Dropbox links, even though it doesn't advertise it as a feature.
