Avoid the "Video is too large" Error

We've all seen it: you try to attach a video, and Gmail says "Large files must be shared with Google Drive." This is annoying for you and the recipient.

  • Permissions Issues: "You need request access to view this file."
  • External Friction: The user has to leave their inbox to watch it.
  • Ignored Emails: People often ignore links they don't recognize.

The "Under 25MB" Strategy

Direct Playback

MP4 files under 25MB often play directly inside the email client (especially Gmail and Apple Mail).

Instant Access

No loading external sites. The video is right there.

Email video compressor FAQ

Answers about 25MB limits, quality, and supported formats.

How do I send a video larger than 25MB?+
Normally, you'd have to use a cloud link (Google Drive/Dropbox). However, with Cubix, you can compress that 50MB or 100MB video down to under 25MB and attach it directly.
What is the size limit for Gmail attachments?+
Gmail has a strict 25MB limit for all attachments combined. If your video is 26MB, it will force you to use a Drive link.
Will the video look bad if compressed to 25MB?+
Not necessarily. For short videos (under 2-3 minutes), we can maintain decent quality (720p) while staying under 25MB. For longer videos, resolution might drop.
Which format is best for email?+
MP4 (H.264) is the safest bet. It works in Gmail preview, Outlook, and Apple Mail without requiring the recipient to download a special player.
Does this work for Outlook and Yahoo?+
Yes. Outlook generally has a 20MB limit (sometimes 25MB) and Yahoo has 25MB. Our tool targets these specific sizes.
