# How to compress a video on iPhone

**Short answer:** iOS has no built-in "compress" button. Change **Settings › Camera › Record Video** to **1080p at 30 fps** with **Formats › High Efficiency** for new videos, and use an on-device compressor such as Spaceclear for the videos you already have: it re-encodes them in HEVC, keeps the date, location and HDR, and only removes the originals after you review them.

## Steps
1. For new videos: **Settings › Camera › Formats › High Efficiency**, and **Record Video › 1080p at 30 fps**.
2. For existing videos: open [Spaceclear](/) › **Compress Videos**, choose **High** (1080p), **Balanced** (720p) or **Small** (540p).
3. Select the videos (biggest first) and check the estimated savings.
4. Tap **Compress**. When it's done, review the originals and delete them.

## FAQ
### Does compressing lose quality?
Some, but at 1080p on a phone screen it's hard to see. Spaceclear's High setting is meant to look the same on an iPhone.

### Are my videos uploaded to compress them?
Not with Spaceclear: compression runs on the iPhone. Online compressors upload your video.
