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.
- Open the Altols email video compressor.
- Choose your video. It's processed on your device, not uploaded.
- Pick 25 MB for Gmail, or 10 MB for a strict work server, and click Compress video.
- 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.
Option 2: Send a link
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.
