How it works

How to compress a video

Drop, compress, download — all local.

01
Drop your video
Add an MP4, MOV, or WebM file, or click to browse. It stays on your device.
02
Compress it
VidTools shrinks the file in your browser while keeping it looking sharp.
03
Download the smaller MP4
Save the compressed video, ready to send, upload, or post.

What it's good for

Get videos under the limit

Big video in, shareable video out

Email & chat limits

Shrink a clip so it fits under an attachment or message size cap.

Faster uploads

Compress before posting so uploads finish quickly.

Saving storage

Keep a lighter copy of a recording without losing much quality.

Web & embeds

Serve a smaller file so pages and previews load faster.

How it works

A video compressor that runs in your browser

Most online video compressors make you upload a huge file to a stranger's server and wait. VidTools compresses your video locally, right in this tab, so nothing is uploaded and nothing is stored. Drop an MP4, MOV, or WebM and export a smaller MP4 with no watermark and no noticeable drop in quality.

Local, private, and fast

Because the work happens in your browser, there's no upload wait and no data policy to trust. Your video stays with you from start to finish, and the compressed file downloads straight back to your device.

Compress, split, or convert

If a video is still too long rather than too heavy, use the Video Splitter to cut it into clips. Need a different format entirely? Run it through the Media Converter.
