How to compress a video

  1. 1. Add a video. Drop an MP4, MOV or WebM file onto the compressor, or tap Choose file.
  2. 2. Choose a target. Pick a size (10 MB, 16 MB, 20 MB or a custom number) and the compressor works out the bitrate for your clip’s length, or pick High, Balanced or Smallest quality.
  3. 3. Compress and download. Press Compress video, compare the before and after size, preview it, then download the MP4. Free, no watermark.

Frequently asked questions

How do I compress a video without losing quality?
Choose the High quality preset, which re-encodes to efficient H.264 at a near-original quality level and usually shrinks phone and screen recordings a lot. If you need a specific size, pick a target and the compressor spends every available bit on the picture, lowering resolution only when the size cannot carry the original sharply.
How do I get a video under 10 MB or 16 MB?
Pick the 10 MB, 16 MB or 20 MB target (or type your own), then press Compress video. It calculates the bitrate from the clip’s length, keeps a safety margin, and re-runs once at a lower bitrate if the first pass lands over. If a long clip cannot fit and still look watchable, it tells you the smallest sensible size so you can trim first.
Is my video uploaded to a server?
No. Compression happens in your browser and the file never leaves your device. Nothing is uploaded unless you sign in and choose to save the result to your library.
Why is compressing slower than uploading to an online site?
The encoding runs on your own device instead of a remote server, which is what keeps your footage private. Short clips finish quickly; long or 4K videos take longer, and files over 500 MB show a memory warning. Keep the tab open until it finishes, or press Cancel.
What formats does it support?
MP4, MOV and WebM in; an H.264 MP4 with AAC audio out, which plays almost everywhere, including Discord, WhatsApp, email and social apps. There is no watermark and no sign-up.
