Reduce video file sizes by 50-80% while keeping visual quality intact. Free up gigabytes of iPhone storage in minutes.
iPhone videos are recorded at extremely high quality, which means massive file sizes. Here's what your videos are really costing you:
| Video Quality | Size per Minute | 10-Minute Video | After Compression |
|---|---|---|---|
| 1080p HD at 30fps | 60 MB | 600 MB | ~200 MB (67% saved) |
| 1080p HD at 60fps | 90 MB | 900 MB | ~300 MB (67% saved) |
| 4K at 30fps | 170 MB | 1.7 GB | ~500 MB (71% saved) |
| 4K at 60fps | 400 MB | 4 GB | ~1.2 GB (70% saved) |
* Compression savings based on Medium quality setting. Actual results may vary.
Fast Cleaner makes video compression simple. Here's the process:
Get the app free from the App Store and grant access to your photo library when prompted.
Open Fast Cleaner and tap the "Compress Videos" feature to see all your videos sorted by size.
Select Low (30% smaller), Medium (50-60% smaller, recommended), or High (70-80% smaller) compression.
Tap "Compress" and wait for processing. Save the compressed version to replace the original and instantly reclaim storage.
The smartest way to compress videos on your iPhone:
Compress multiple videos at once. No need to process them one by one — select all large videos and compress in a single session.
See the compressed video before replacing the original. Compare quality and file size to make sure you're happy with the result.
Before and after file sizes shown clearly. Know exactly how much space you'll recover before committing.
Videos never leave your iPhone. All compression happens locally — nothing is uploaded to any server. Your privacy is protected.
Optimized for Apple Silicon. Compress videos quickly even on older iPhones. Processing runs in the background.
Modern HEVC compression maintains visual quality while dramatically reducing file size. Ideal for sharing and storage.
Use Fast Cleaner's video compression feature. Download the app, select "Compress Videos," choose your videos, and pick Medium compression for the best balance of size reduction and quality. Modern compression can reduce files by 50-80% with virtually no visible difference on phones and tablets.
No, iPhone doesn't have a built-in way to compress existing videos. You can only change recording quality for future videos (Settings > Camera > Record Video). To compress videos already on your phone, you need an app like Fast Cleaner.
It depends on recording quality. 1080p at 30fps uses ~60MB per minute. 4K at 60fps uses ~400MB per minute. A 5-minute 4K video can consume 2GB. If you record often at high quality, videos can easily take up 20-50GB of your storage.
Not at recommended settings. Medium compression produces videos that look virtually identical to originals when viewed on phones, tablets, or most TVs. Quality loss is only noticeable when zooming in significantly or viewing on large 4K displays up close.
About 10-30 seconds per minute of video, depending on your iPhone model. Newer iPhones compress faster. You can queue multiple videos and let them process while you do other things — compression runs in the background.
Compression replaces the original, so back up important videos first. However, if you use iCloud Photos, the original may still be in iCloud for a while. For truly irreplaceable videos, consider keeping originals on a computer or external drive.
