CapCut requires between 200 MB and 500 MB of free storage to install, depending on your device and operating system, but you will need significantly more space to actually use it
The app itself is small — roughly 200 MB on Android and 300 to 500 MB on iOS. However, the real storage demand comes from the video files you edit. A single minute of 1080p video takes up 100 to 150 MB. A 10-minute video project can easily consume 1 to 2 GB of space, and CapCut creates temporary files during editing that can double your storage needs temporarily.
If you plan to edit videos regularly, you should have at least 5 to 10 GB of free space available on your device. This gives you room for the app, your project files, and the working files CapCut generates while you edit. Without this buffer, your device may slow down, crash during export, or prevent you from saving your work.
Key Takeaways
- CapCut itself takes up 200 to 500 MB depending on whether you use Android or iOS.
- Video files are the real storage burden — one minute of 1080p video occupies 100 to 150 MB.
- CapCut creates temporary working files during editing that can use as much space as your original video, so you need roughly double your project size in free space.
- For regular video editing, keep at least 5 to 10 GB of free storage available on your device.
Storage needs on Android versus iOS
Android devices typically require 200 to 300 MB of free space to install CapCut from the Google Play Store. iOS devices need 300 to 500 MB from the App Store. Both platforms also need additional space for the system to function — most devices reserve 1 to 2 GB for operating system operations, so your actual usable free space should be higher than the app's minimum requirement.
Android users have an advantage: you can move CapCut to an external SD card if your phone has one, which frees up internal storage. iOS does not allow this, so iPhone and iPad users are limited to their device's built-in storage. If you have a 64 GB iPhone and plan to edit video, you will fill it quickly.
How video resolution affects file size
The resolution of your video determines how much storage each minute of footage consumes. A one-minute video at 720p uses roughly 60 to 80 MB. The same video at 1080p uses 100 to 150 MB. At 4K resolution, one minute jumps to 300 to 500 MB or more, depending on the frame rate and bitrate.
When you export your finished video from CapCut, the file size depends on the resolution and quality settings you choose. Exporting a 10-minute video at 1080p typically produces a file between 1 and 2 GB. If you export at 4K, expect 3 to 5 GB or larger. CapCut also keeps your original project file, which is separate from the exported video, so both take up space.
Temporary files and working space during editing
CapCut creates temporary cache files while you edit — these are working copies of your video, effects, and transitions. These files can be as large as your original video or larger, depending on how many effects and layers you add. If you are editing a 2 GB video project, CapCut might use an additional 2 to 4 GB of temporary space while you work.
This is why having free space matters more than the app's installation size suggests. If your device only has 500 MB free, CapCut will either run very slowly, crash during export, or refuse to save your work. Once you export and delete the project, CapCut clears these temporary files, but they occupy space while you are actively editing.
Clearing cache and managing storage on your device
If you are running low on storage, you can clear CapCut's cache without losing your projects. On Android, go to Settings > Apps > CapCut > Storage > Clear Cache. On iOS, you can only clear cache by uninstalling and reinstalling the app, which also deletes your projects unless you have saved them to the cloud.
You can also delete old projects from within CapCut. Open the app, find the project you no longer need, and swipe or tap to delete it. This removes both the project file and its associated temporary files. If you want to keep a project but free up space, export it to your device, then delete the project from CapCut — the exported video file remains in your photo library or file system.
Cloud storage and CapCut's backup options
CapCut allows you to save projects to the cloud through your account, which moves some of the storage burden off your device. However, the app does not automatically back up to cloud storage — you must manually save each project. The cloud storage is useful if you want to edit the same project on multiple devices or keep a backup, but it does not reduce the storage you need on your phone while actively editing.
Exported videos can be uploaded to cloud services like Google Drive, iCloud, or Dropbox after you finish editing. This frees up device storage while keeping your finished videos accessible. Many people export to their device, upload to the cloud, then delete the local copy to reclaim space.
Minimum device storage recommendations by use case
| Use Case | Recommended Free Storage | Why |
|---|---|---|
| Light editing (short clips, occasional use) | 2 to 3 GB | Room for app, a few small projects, and temporary files |
| Regular editing (multiple projects per week) | 5 to 10 GB | Multiple projects, working files, and buffer for exports |
| Heavy editing (4K video, daily use) | 15 to 20 GB | Large video files, many temporary files, multiple projects in progress |
| Professional work (multiple 4K projects) | 50+ GB | Large files, extensive effects, need for fast performance and backups |
Frequently Asked Questions
Can I use CapCut on a phone with only 64 GB of storage?
Yes, but only for light editing. A 64 GB phone with the operating system, apps, and photos already installed typically has 20 to 30 GB of actual free space. This is enough for short video projects, but you will need to delete old projects frequently to make room for new ones. For regular video editing, a device with 128 GB or more is more practical.
What happens if my device runs out of storage while I am editing?
CapCut will likely crash or freeze, and you may lose unsaved work. The app needs space to write temporary files, and without it, the export process will fail. Always keep at least 1 to 2 GB of free space available before you start editing, and check your device storage before exporting.
Does CapCut use cloud storage automatically?
No. CapCut stores projects locally on your device by default. You can manually save projects to the cloud through your CapCut account, but this is optional and does not happen automatically. Exported videos are saved to your device's photo library or file system unless you manually upload them to cloud services afterward.
Can I edit videos on an external storage device with CapCut?
On Android, you can store videos on an SD card and import them into CapCut, but the app itself and your projects must be on internal storage. On iOS, there is no external storage option — everything stays on the device. CapCut cannot directly access or edit files from external drives on either platform.
How do I know how much storage my videos are using?
On Android, open Files or your file manager, navigate to your DCIM or Movies folder, and check file sizes. On iOS, open the Photos app, select a video, tap the info icon, and view its size. You can also check CapCut's project storage by opening the app and looking at individual project details, though CapCut does not always display exact file sizes clearly.
