How to use it

  1. 1Drop a video onto the box, or click to choose a file from your device.
  2. 2Pick a compression level — High quality, Balanced, or Small file.
  3. 3Click Compress video, then download the smaller MP4 once it finishes.

Big video files are a constant headache. Email attachments bounce off size limits, upload forms reject anything over a few megabytes, chat apps refuse to send, and cloud storage fills up fast. Compressing a video brings the file size down so it actually fits — and as a bonus, smaller files upload and share far faster, which matters when you are sending a clip to a client or posting it to social.

Screen recordings are the worst offenders. A few minutes of a high-resolution capture can balloon into hundreds of megabytes because every pixel of the screen is encoded frame by frame. Running that recording through a compressor can cut the size dramatically while keeping it perfectly watchable, so you can attach it, embed it, or hand it off without wrestling with a giant file.

This tool does it all locally. Your video is processed entirely inside your browser using an in-browser video engine — there is no upload, no server, no watermark, and no account. The file you drop in stays on your machine the whole time, which makes it safe for confidential demos, client work, and anything you would rather not hand to a website.

The compression level lets you trade quality against size. High quality keeps the picture crisp and saves less space; Small file squeezes harder and gives you the smallest result at some visible cost; Balanced sits in the middle and is the right pick for most clips. Pick a level, compare the before and after sizes, and download a standard MP4 that plays everywhere.

FAQ

Is this tool free?
Yes — completely free, with no sign-up, no watermark, and no limits. It runs in your browser.
Is my video uploaded anywhere?
No. Everything happens locally in your browser. The video is never sent to a server — it stays on your device the entire time.
Will compressing reduce the video quality?
Compression re-encodes the video, so there is always some trade-off between size and quality. The High quality level keeps the picture crisp with a smaller saving, while Small file shrinks the most at a more visible cost. Balanced is a good default for most clips.
What formats does it support?
It accepts MP4 and most common video formats. The compressed file is saved as a standard MP4 that plays everywhere and imports into editors.
Why does the first run take a moment?
The first time you use it, your browser downloads the in-browser video engine (about 30 MB) once. After that it is cached, so later runs start instantly.
