Gmail's attachment limit is 25 MB. Above this threshold, Gmail converts your attachment into a Google Drive link — the recipient needs a Google account and your permission to open it. Compressing your video to under 25 MB keeps it as a genuine email attachment that opens with one click in any email client, on any device, without a Google account.
When you need 25 MB
- Gmail video attachments (25 MB hard cap)
Gmail won't send video files above 25 MB as attachments. Files above this limit are automatically converted to Drive links.
- Client review clips via email
Short product demos, interview clips, and feedback recordings compressed to 25 MB send cleanly from any email provider.
- Wedding or event highlights
2–5 minute highlight reels for sharing with family via email fit comfortably under 25 MB at 720p.
