Email hates big videos
Email was never built for large files. Gmail caps attachments at 25MB, Outlook at around 20MB, and plenty of workplace servers are stricter still. The limit counts the entire encoded message, so a “20MB” video can tip a 25MB inbox over the edge. Go past it and Gmail silently swaps your attachment for a Drive link — or the message just bounces.
Mynify shrinks the video on your device so it slips comfortably under those limits and arrives as a real, downloadable attachment — with nothing uploaded to us along the way.
How the email preset works
This page uses the Super small setting — maximum compression — so even a few minutes of video can fit an attachment limit. Mynify re-encodes to a compact H.264 MP4 that opens on any mail client, phone, or computer, and shows you the estimated size before you send. If it’s still a touch large, switch to a stricter setting or trim the clip.
Where your browser supports it, compression runs on your device’s hardware encoder for speed; otherwise a universal fallback engine handles it. Either way it’s a standard MP4 your recipient can just double-click.
Getting it under the limit
- Trim ruthlessly. For email, the shortest clip that makes your point compresses best and respects the recipient’s inbox.
- Aim under 20MB, not exactly 25. Encoding overhead and mail-server rules make a little headroom worthwhile.
- Watch corporate limits. Many workplace mail servers are stricter than Gmail — 10MB is common. If you’re emailing a work address, aim smaller and confirm it arrived.
- For big or long videos, consider a link. If even maximum compression won’t fit, a shared link is kinder than a bounced message — but for most short clips, this preset does the job.
No signup, no watermark, no limits — and because it’s fully local, the video you’re emailing stays entirely on your device.
