To compress a video on Android, open the MobileStudio Video Compressor in Chrome, pick your video, and choose a target size such as 25 MB. It runs right in the browser, so there's no app to install and the video stays on your phone. To make future videos smaller, record at 1080p instead of 4K.
The short answer
| Goal | Best way on Android |
|---|---|
| Send a video under a limit (email, Discord) | Browser compressor with a target size |
| Shrink many old videos | Re-record settings won't help; compress them one by one |
| Smaller videos from now on | Record at 1080p, not 4K |
| Free up phone storage | Back up to the cloud, then delete originals |
How do I compress a video on Android without an app?
- Open Chrome and go to the MobileStudio Video Compressor.
- Tap the drop area and choose the video from your gallery or files.
- Pick 10 MB, 20 MB (Discord), 25 MB (email), or a custom size.
- Leave Resolution on Auto and tap Compress.
- Tap Download MP4. The file lands in your Downloads folder, ready to share.
Auto picks the sharpest resolution that fits the size. A 30-second clip stays 1080p at 25 MB but drops to 720p at 10 MB, because a clean 720p looks better than a blocky 1080p.
Why are Android videos so big?
Most flagship Android phones can record 4K at 60 fps, and some default to high resolutions. A minute of 4K video can run to hundreds of megabytes. File size is roughly bitrate times length, so high resolution and long clips add up fast. The underlying idea is explained in how to compress a video.
How do I record smaller videos on Android?
Lower the recording resolution in your camera:
- Samsung Galaxy: in the Camera app's Video mode, tap the resolution label (such as UHD or FHD) and choose FHD (1080p).
- Google Pixel: in Video mode, open the settings and choose 1080p instead of 4K.
1080p at 30 fps is plenty for social media, chat apps, and most screens. Keep 4K for footage you'll edit or watch on a big TV.
Can Google Photos compress videos?
Not the file on your phone. Google Photos can trim, crop, rotate, and stabilize videos, as its video editing help describes, but it doesn't offer a file size setting when you save. Its backup quality setting affects the copy stored in your Google account, not the original on your phone.
How do I free up space without deleting videos?
Back up your videos to Google Photos, Google Drive, or another cloud service, then remove the originals from the phone. On Samsung, the Gallery app's own tools help you find large items, as Samsung's Gallery guide shows. For individual videos you want to keep on the phone, compress them to a smaller size instead.
What size should I compress to?
| Where it's going | Size to choose |
|---|---|
| Gmail | 25 MB, which is Gmail's attachment limit |
| Discord (free) | 20 MB |
| Quick shares and forms | 10 MB |
| Phone storage | Whatever looks fine on your screen |
If you also record your screen, the same tool works on those recordings. See how to screen record on Android.
