Frequently Asked Questions

What is the maximum video size for email?

Gmail and Outlook both limit attachments to 25 MB. Many corporate mail servers enforce tighter limits of 10 MB or 5 MB. Aim for under 10 MB to ensure delivery to any recipient.

Which preset should I use for email?

Use Fast for the smallest output file. A typical 1-minute 1080p clip compresses to 5–15 MB on the Fast preset — well under most email limits. Use Balanced if quality matters more than file size.

What if the compressed video is still too large?

Try trimming the video to a shorter clip first using our Video Trimmer, then compressing. Alternatively, upload to Google Drive or Dropbox and share the link in your email.

Is my video kept private?

Yes. Your video and the compressed output are automatically deleted within 60 minutes. We never store or analyse your files.
