Gmail Attachment Size Limit for Video
Gmail video attachments are limited by Gmail attachment size rules. Most videos need to be compressed, shortened, or sent with a Drive link before they can be shared.
Pick the PDF, image, or video you want to email. The size check is free.

Sending to work or school?
You do not normally need this. If you are sending to a work, school, or company address, paste it here and we will check the mail service when we can.
You can leave this empty. It is only here if you want to check a work, school, or company email address.
Optional Devenia help
Rather have us make the smaller copy?
The check and advice above are free. You can try the changes yourself, or ask Devenia to make a smaller copy for you.
We use this to send the finished file and receipt.
What this page is for
This page is for videos that are too large to attach directly in Gmail. Even short videos can exceed the limit when recorded at high resolution or high bitrate.
A smaller MP4 export is usually the cleanest option when the video must stay as an attachment.
How to handle it
- Check the video file size before attaching it.
- Export a smaller MP4 copy with H.264 when possible.
- Reduce resolution or bitrate before cutting important content.
- Play the smaller video from start to finish.
- Use Google Drive if the video still cannot fit.
What to check before sending
- Open the smaller file before sending it.
- Check the final file size, not just the compression setting.
- Keep the original file until the recipient confirms the smaller copy works.
- Make sure important text, faces, forms, signatures, or charts are still clear.
