How to compress a video to 50 MB

Choose a video and keep the 50 MB target, or enter another limit. The compressor picks a bitrate and resolution that fit, encodes the video in your browser, and measures the finished file before offering the download.

  1. Step 1

    Choose a video
    Pick the file that needs to fit under 50 MB.

  2. Step 2

    Set the limit
    Keep 50 MB or enter another target size.

  3. Step 3

    Download the result
    Save the video after its final size is verified.

What to expect

Supported inputs
Any media file this browser’s engine can read.
What happens
The default limit is 50 MB. Bitrate is estimated from the limit and source size, and the resolution steps down when the budget is too tight for a sharp picture. The output is checked against the limit and the original file size. A smaller input is never intentionally expanded to fill the limit.
Limits
A bitrate estimate is not a size guarantee. Very short size budgets, unsupported codecs, or device memory limits can prevent a valid export.
