How to email a video that's too big to attach

Email was never designed for video. Gmail lets you attach up to 25 MB, and a minute of phone video is often bigger than that. You have two good options: make the video small enough to attach, or send a link to it.

Email attachment limits

  • Gmail lets you send up to 25 MB of attachments per email, in total. You can receive emails up to 50 MB.
  • If you attach something bigger, Gmail uploads it to your Google Drive and puts a link in the email instead.
  • Work and school email servers often set lower limits. If a message bounces, aim for 10 MB.

Option 1: Compress the video so it attaches

Best for short videos, and when you want the person to be able to play it straight from the email.

  1. Open the Altols email video compressor.
  2. Choose your video. It's processed on your device, not uploaded.
  3. Pick 25 MB for Gmail, or 10 MB for a strict work server, and click Compress video.
  4. Download the MP4 and attach it to your email.

Remember the limit is for the whole email. If you're sending two videos, give each one a smaller target, such as 12 MB.

Best for long videos, or when full quality matters, such as a video for work or a wedding clip for family.

  • Gmail: attach the big file anyway and Gmail switches it to a Google Drive link automatically. Make sure the sharing setting lets the recipient open it.
  • iPhone Mail: when an attachment is too big, Mail offers to send it with Mail Drop, which handles files up to 5 GB.
  • Any email: upload the video to Google Drive, OneDrive or Dropbox and paste the share link into your message.

Frequently asked questions

Why did my video turn into a Google Drive link?

Gmail does this automatically when attachments add up to more than 25 MB.

Will the person need special software to play the video?

No. Altols produces an MP4 with H.264 video, which plays on Windows, Mac, iPhone and Android without any extra software.

Is the 25 MB limit per file or per email?

Per email. All the attachments together must fit under 25 MB.
