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 —50MB, 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 — 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.
Regularly emailing large batches of videos to clients or a team? The Shrynk desktop app can batch-compress a whole folder to a target size automatically, for a one-time $9.
