Compress Video for iMessage
iMessage compresses videos hard when your connection is weak, and falls back to MMS (capped near 100MB or lower by carrier) when iMessage is unavailable. Pre-compressing keeps the quality you choose and avoids send failures.

iMessage and MMS size limits
When iMessage can't send (recipient on Android, or iMessage is down), it falls back to MMS, which carriers cap between 300KB and 100MB. iMessage itself also re-compresses large clips. Compressing to ~100MB or less keeps videos sendable both ways.
Frequently asked questions
- Why does iMessage make my videos blurry?
- On slow connections iMessage drops the bitrate aggressively to send faster. Compressing to a sensible size yourself gives a predictable result instead of letting iMessage decide.
- What's the limit when it sends as a text (MMS)?
- Carrier-dependent, often around 100MB on modern networks but as low as 300KB–1MB on older ones. Compress below that to ensure green-bubble recipients can receive it.
