How to Reduce Video File Size
File size drops when the picture is smaller, the frame rate is lower, or the bitrate is lower. You cannot keep every pixel and also keep a tiny file.
This downloader will not shrink a video for you. It can only offer the smaller file if the platform already made one.
Quick answer. On a download, choose SD when it is listed. On an iPhone recording you have not made yet, set Settings, Camera, Record Video to 1080p at 30 fps, or 720p if that model still offers it.
The only size control on this site
HD, SD, and Auto appear when you paste a link. SD is the smaller rendition. If the two buttons save the same size, the platform published one file. Tapping SD cannot create a lighter copy.
Do not run the video through a random compressor site afterward if you care about the picture. Many of them re-upload your file. A normal editor on your own computer, exporting H.264 at a lower bitrate, is the straightforward way to shrink a file you already have.

Shrink the recording instead
4K at 60 fps is the setting that fills a phone. 1080p at 30 fps is the setting that leaves room. Change it before you press record.
On iPhone the path is Settings, Camera, Record Video. The list includes a storage estimate. That estimate is for the camera, not for a Reel you download later.
What does not work
Renaming the file does nothing to the size. Zipping a video barely helps, because the video is already compressed, and the other person has to unzip it.
Sending it through a messaging app often recompresses it without telling you the settings. That is a smaller file, and it is also a blurrier one. Watch it before you delete the original.
Shrink a file without ruining it
The easiest reduction is to save the SD or 720p rendition when the downloader lists it. That choice happens before the file is on your phone. Converting afterward takes longer and can look worse.
On a computer, a simple export at 1080p and a moderate bitrate is enough for social apps. Do not stack two compressions. If the clip already looks soft, another pass will not make it cleaner.
This website does not compress files for you. It saves the rendition you pick. If you need a smaller file than every listed option, use a video editor after the download.
Frequently asked questions
Will SD look bad?
It is the platform's smaller file. Play the preview. If it is soft, the HD file is the one to keep.
Can you compress a video I already downloaded?
No. The tool does not upload your camera roll or recompress a finished save.
Does a shorter clip always mean a small file?
Shorter helps, but 10 seconds of 4K can outweigh a minute of a compressed Reel.
