How it works
Three steps to a smaller video.
02
Pick a range & quality
Choose the start and end you want (up to 10 minutes) and a preset — Strong for the smallest file, Balanced for the best trade-off, or Light to keep the most quality.
03
Preview & download
The video is compressed in your browser. Play it on the page to check it, see how much smaller it is, then download the file.
Quality presets
Strong, Balanced, or Light — your call.
Strong — scales down to 480p for the smallest file. Best for sharing and tight storage, with the most quality loss.
Balanced — 720p with a strong size cut and good quality. The recommended default for most clips.
Light — keeps the source resolution for the least quality loss, with a smaller saving. Best when quality matters most.
Performance & privacy
Private by design — and honest about speed.
Nothing is uploaded — your video is compressed entirely on your device, so it stays private.
Compression is a full re-encode that runs on a single thread in the browser, so it can take a while on longer or higher-resolution clips — a progress bar shows how it's going.
A smaller file means a lower bitrate or resolution, so there's some quality loss; the presets make that trade-off clear, and Balanced is a good place to start.
No account, no watermark, no install — it runs in the browser you already have open.
Need more than a smaller file?

FAQ
Compress video questions
How do I compress a video online for free?
To compress a video online for free, drop a video file onto the box on this page or choose one. Pick the part you want and a quality preset (Strong, Balanced, or Light), then select Compress video. The video is re-encoded into a smaller MP4 in your browser and offered as a download you can also preview first.
Is my video uploaded to a server?
No. The video stays on your device. It is decoded and re-encoded entirely in your browser — nothing is uploaded, and the smaller video is returned straight to you as a download.
How much smaller will my video be?
It depends on the preset and the source. Strong scales down to 480p for the smallest file, Balanced uses 720p for a strong size cut with good quality, and Light keeps the source resolution for the least quality loss. After it runs, the page shows the before and after size and the exact percent saved.
Why does compressing take a while?
Compression is a full re-encode that runs on your own device, with no server doing the work. In the browser it runs on a single thread, so longer or higher-resolution clips take longer. A progress bar shows how it is going — keep the tab open. Shorter clips and the Balanced preset are the fastest.
Which video formats are supported?
Common video files work — MP4, MOV, WebM, MKV, and more. The output is always a compressed MP4 (H.264 video with AAC audio) so it plays almost everywhere. Each compression handles a range of up to 10 minutes; for a longer file, compress it in parts.
Is it free and do I need to sign up?
It is free and there is no sign-up. Because everything runs in your browser, there is no usage limit on compressing video.
