Illustration
Photos sorts by date. Metras sorts by size.
In Photos, albums sort by date or in your own order, not by size. Metras scans your library and puts the heaviest videos first, so you can see where the space went and free up storage on iPhone.
- IMG_4120.MOV 7:42 1.21 GB

Limits
Where the limits are.
Most email stops at 20 or 25 MB. A minute of 1080p video is about 70–105 MB, so it rarely fits as it is. Compress videos on iPhone to a size under the limit first.
Two ways
Two ways to a smaller file.
On a computer
The browser compressor
Free, right in your browser, on Windows or Mac.
Files never leave your device.
Questions
Are my videos uploaded anywhere?
No. Metras makes the copies on your iPhone, and nothing is uploaded to a server. The browser compressor works the same way: files are processed in your browser and never leave your device.
Does Metras delete my originals?
No. Originals are never deleted automatically. Compare the copy with the original, then decide what to keep.
Which size should I choose for email?
25 MB for Gmail, Yahoo Mail and Outlook.com on the web. 20 MB for iCloud Mail and the Outlook app. 10 MB for strict work servers. See every limit, with sources.
What does the video compressor for iPhone and Android cost?
Metras will be free to download, with up to 3 files per batch. A one-time Premium purchase unlocks large batches, with no subscription and no ads. It is available for iPhone (iOS 15 or later) and Android (8.0 or later). On a computer, use the browser compressor.
How to make videos smaller on iPhone?
Choose the videos in Metras, pick a size such as 25 MB for email or a balanced reduction, and check the estimate. Metras then makes the smaller copies on your iPhone, and your originals stay in Photos until you decide what to keep.
How to make videos take up less space on iPhone?
Metras scans your library and puts the heaviest videos first, so you see where the space went. Choose them, pick a balanced reduction, and it makes lighter copies on your iPhone. Compare each copy with its original, then decide what to keep. Nothing is deleted automatically. To see how much space your videos would free before you start, compress videos to save space adds it up in your browser.
How can I send a video that is too large on iPhone?
Make a smaller copy first. A minute of 1080p video is about 70–105 MB, and most email stops at 20 or 25 MB. In Metras, pick the size your email accepts, such as 25 MB for Gmail, check the estimate, and send the copy. The video size calculator shows how long a video fits in each size.
