Compress a video

Ethical Tube's free video compressor makes MP4, MOV, WebM, and MKV videos smaller by re-encoding them at a lower bitrate and, if you like, a lower resolution, right in your browser. Pick a preset or type a target size, like 10 MB for Discord or 25 MB for Gmail, and compare the size before and after. Your videos are never uploaded, and there's no sign-up or watermark.

How it works

How to compress a video

  1. Add your video

    Drop an MP4, MOV, WebM, MKV, or other video onto the page, or click to choose one.

  2. Pick a preset or a size

    Balanced works for most videos. Choose Target size to hit a limit like 10 MB, and lower the resolution for the smallest files.

  3. Compare and download

    The new size is shown next to the original, so you can check the savings before you download.

Good to know

How much smaller will it get?

  • Phone videos are recorded at a high bitrate, so they often shrink by half or more at the Balanced preset with little visible change.
  • Lowering the resolution from 1080p to 720p roughly halves the size again. 480p is fine for phone screens and chats.
  • Screen recordings and talking-head videos compress very well because little changes between frames.
  • In Target size mode, the bitrate is calculated from the video's length, and the result usually lands within a few percent of the size you ask for.
  • The result is an MP4 with H.264 video and AAC audio, which plays on every phone, computer, and website.

FAQ

Questions, answered

Is the video compressor free?

Yes. It's completely free, with no sign-up, no watermark, and no limit on how many files you process. It costs Ethical Tube nothing to run, because the work happens on your own device rather than on a server.

Are my files uploaded anywhere?

No. Everything happens inside your browser, so your files never leave your device. Once the page has loaded, the tool even works offline.

How do I compress a video for Discord?

Choose Target size and enter 10 MB, the upload limit for free Discord accounts, or the higher limit of your Nitro plan. Keep a little margin, like 9.5 MB, to be safe.

How do I make a video small enough to email?

Gmail and Outlook allow attachments of about 20 to 25 MB. Choose Target size and enter 20 MB. For long videos, also lower the resolution to 720p or 480p so the picture stays sharp at the lower bitrate.

Does compressing reduce quality?

A little, because the video is re-encoded at a lower bitrate. At the Balanced preset the difference is hard to see on a phone or laptop. Small files and very long videos show more softening, especially in fast motion.

Does it work on iPhone and Android?

Yes, in current versions of Safari, Chrome, and Firefox. Short clips compress quickly on a phone. Long or 4K videos are faster on a computer.
