About Video converter

Change the container or codec so a video plays where you need it: MP4 for universal playback, WebM for the web, MOV for Apple apps. When the codec is already compatible the tool remuxes without re-encoding, which takes seconds and loses nothing.

  • Choose Make it play anywhere for a fast MP4 that works on phones, TVs and in browsers.
  • Re-encoding is only needed when the codec changes; the tool tells you which path it will take.
  • Keep the original frame rate unless you have a reason to change it.

How to use it

  1. 1Drop a video.
  2. 2Pick the output format and, if needed, a codec and quality.
  3. 3Convert and download.

Questions

Why will my MKV not play on my phone?
MKV is a container most phones do not open. Converting to MP4 usually just repackages the same video without quality loss.
Does converting reduce quality?
Remuxing is lossless. Re-encoding at the default quality is visually identical.
Is anything uploaded?
No. Everything runs in your browser, so your files never leave your device.
