Email wasn't designed for video. Most services cap attachments at around 25 MB, and a one-minute phone video in full quality can be 200–500 MB — ten to twenty times that. Compressing helps for short clips; for anything longer, a link is simply the more practical choice.
When Compression Alone Is Enough
For a short clip — a few seconds to about a minute — you can usually compress it into a file small enough for email attachment.
- Open Video Compressor.
- Upload the video.
- Choose a quality setting appropriate for email — lower resolution and moderate bitrate will do.
- Check the file size of the result before attaching.
Target around 20 MB to leave a comfortable margin below most services' 25 MB limit. For bitrate guidance, see what is video bitrate and how does it affect quality.
Choosing the Right Settings for Email
| Priority | Setting |
|---|---|
| Smallest file | Reduce to 480p or 720p, low bitrate |
| Reasonable quality | 720p, medium bitrate (around 1,000 kbps) |
| Keep 1080p | Only if the clip is very short; file will be larger |
For an email video that will mainly be watched on a laptop or phone screen, 720p is usually the right call — video resolution explained has more on why.
When to Use a Link Instead
For anything longer than a minute, or where quality really matters, uploading to a file-sharing service and emailing the link is the standard approach:
| Service | Free limit | Notes |
|---|---|---|
| Google Drive | 15 GB free | Accessible to anyone with a Google account |
| Dropbox | 2 GB free | Simple link sharing |
| YouTube | Effectively unlimited | Set to "Unlisted" to share without publishing publicly |
| WeTransfer | 2 GB free | Links expire after several days |
Google Drive is the most convenient option for most people — upload the video, right-click → Share → "Anyone with the link", and paste the URL into the email body.
Common Problems
- Attachment blocked: some corporate email servers block video formats entirely — use a link even if the file is small.
- Attachment stripped: some antivirus software on the recipient's end may strip video attachments — a link bypasses this.
- Recipient's inbox full or mailbox limit exceeded: a large attachment can cause delivery failures even if your server accepted it — again, a link avoids this.
Quick Decision
| Video length | Best approach |
|---|---|
| Under 30 seconds | Compress and attach |
| 30 seconds to 2 minutes | Try compressing; use a link if it doesn't fit |
| Over 2 minutes | Always use a link |
