Compress Video to 10 MB

Shrink a video to under 10 MB in your browser, with the target already set. Fit to Size is preset to 9 MB; change it after adding a video.

How to Compress a Video to 10 MB

1

1

Add your video

Drop a video onto the page or click to browse. You can add several at once; each one is compressed to the same target.

2

2

Check the target size

Fit to Size is already selected with a 9 MB target. Lower it for extra headroom, or raise it if your limit is bigger.

3

Compress and download

Click Compress. The video is encoded on your own device and downloads when it finishes, in the same container format it came in.

Getting a Video Under 10 MB

Ten megabytes is a common ceiling for attachments, upload forms and chat apps, and a phone video passes it within seconds. This page opens the compressor in Fit to Size mode with the target already filled in, so you can add a clip and compress straight away.

The target is 9, not 10, on purpose. The size box counts binary megabytes (1 MB = 1,048,576 bytes), so 9 is about 9.4 million bytes, and an encoder can land slightly above the size it aims for. That margin keeps the result under a hard 10 MB limit. You can change the number before you compress.

Fit to Size keeps the original resolution and lowers the bitrate to suit the target and the clip's length, so it works best on short clips. At 9 MB a one-minute video gets roughly 1.2 Mbit/s for picture and sound together; a five-minute video gets about a fifth of that and will look noticeably softer.

Compress Video to 10 MB: FAQ

01

Why is the target 9 MB and not 10 MB?

Two reasons. The size box counts binary megabytes, so 10 in the box would be about 10.5 million bytes, which is already over a 10 MB limit counted in millions of bytes. And video encoders hit a target bitrate approximately, so the file can come out a little larger than aimed for. 9 leaves room for both.

02

Will the compressed video be exactly 9 MB?

Close to it, not exactly. The compressor works out a bitrate from the target and the video's length, and the encoder follows that bitrate approximately. A video that is already smaller than the target is not inflated to reach it: the bitrate never goes above the original's.

03

My video is long. Can it still fit in 10 MB?

Sometimes not. The sound keeps its original bitrate and the picture never drops below a minimum bitrate, so a long video can end up above the target, and a very low bitrate looks blocky anyway. Cut the video down first, or split it into parts that each fit.

04

Is my video uploaded to a server?

No. The video is compressed in your browser with WebCodecs, or with ffmpeg compiled to WebAssembly for files the browser cannot handle itself. It stays on your device the whole time, and there is no account and no watermark.
