How to Compress iPhone Videos
Compressing iPhone videos can reduce file size so clips are easier to share, store, send, upload, or keep without filling storage too quickly.
iPhone videos can look great, but they can also become very large. A short recording may be easy to save, while longer or higher-resolution clips can quickly become difficult to send or store.
Compressing a video creates a smaller version that is easier to manage, especially when the original quality is more than the situation requires.

Shrink Video Size
Shrink Video Size supports this workflow with a focused iOS app built for video compression and easier sharing.
Why video compression helps
Compressed videos take less storage and can be easier to send through messages, email, shared folders, or upload workflows.
This is useful when a clip is meant for quick sharing, reference, or documentation rather than high-end editing.
Quality vs file size
Compression usually means balancing quality and size. A smaller file may lose some detail, but that tradeoff can be worth it when sharing speed or storage matters.
Keep the original if the video is important or if you may need the highest-quality version later.
When to compress a video
Compress videos before sending large clips, uploading to a platform with limits, saving long recordings, or keeping reference videos that do not need maximum quality.
Compression is also useful before archiving many videos together.
