How to Compress a Video to Email It
Most email providers cap attachment size well below what a phone video actually weighs. Gmail allows 25MB per attachment (and will auto-switch to a Google Drive link above that), Outlook.com also caps at 25MB, and Yahoo Mail sits at 25MB as well. A 60-second 1080p clip from a modern phone is easily 100–150MB, so it needs to shrink by 80% or more before it'll attach directly.
Why not just use a Drive/Dropbox link?
Links work, but they add friction: the recipient needs to click through, sometimes sign in, and the link can expire or get blocked by corporate spam filters that flag unfamiliar file-sharing domains. A direct attachment under the size limit is simpler and more reliable — especially for one-off videos sent to people who aren't tech-savvy.
How to hit 25MB reliably
- Open Shrynk and drop in your video — everything runs locally, so there's no upload wait either way.
- Choose Target file size mode and set the slider to 20MB, leaving a small buffer under most providers' 25MB cap.
- Download the result and attach it directly — no link, no sign-in required for your recipient.
What quality can you expect at 20MB?
For a video under 90 seconds, 20MB at 720p usually looks clean enough for casual viewing — presentations, quick clips, walkthroughs. For anything longer than 3–4 minutes, you'll want to either drop to 480p or accept more visible compression, since the bitrate budget per second shrinks as duration grows for a fixed file size.
FAQ
What if my video is still too big even after compressing?
Trim the clip to just the relevant section first — cutting length is the single biggest lever for hitting a hard size cap, more effective than any codec setting.
Will the recipient need special software to open it?
No. Shrynk always outputs standard MP4 (H.264/AAC), which plays natively on Windows, macOS, iOS, Android and in every modern browser.
Does this work for outlook.com vs. a company Exchange server?
Corporate Exchange servers sometimes set a lower limit than 25MB (10MB is common). Check with your IT policy, or target 8MB in Shrynk to be safe.
