How to compress a video to 100 MB

Choose a video and keep the 100 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 100 MB.

  2. Step 2

    Set the limit
    Keep 100 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
MP4, MOV, MKV, WebM, MPEG-TS (.ts, .mts), and 3GP videos. AVI, WMV, and FLV files can’t be opened yet.
What happens
The default limit is 100 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.

Your files stay on your device

Your computer does the work, so the file never has to be uploaded, and that’s also why it’s free: there’s no server time for us to pay for. You don’t need an account, and nothing you make gets a watermark.

“Thanks for the video trimmer! I had a file size that was too big for anywhere else and your free one helped a lot!”

Questions

About 2½ minutes at 1080p, or about 5 minutes at 720p. Longer videos are scaled down automatically; for the best picture, trim the clip first.

GitHub blocks files over 100 MiB (about 105 MB), so a video under 100 MB can go in a repository without Git LFS.

The export stops instead of handing you an oversized file. Trim the video, raise the limit, or try a different file.
