Reduce a video’s size: balanced compression, in the browser

Choose the video, leave the level on Balanced and see the estimate of the final size. It is the starting point for reducing most videos with a good look. If you want more control, advanced mode lets you adjust bitrate, audio and frame rate.

Tips for a good result

  • The Balanced level uses 1400 kbps of video and 128 kbps of audio, about 11 MB per minute.
  • Use the player beside it to compare the original with the compressed one.
  • Fast mode uses the graphics card when available; Precise is slower and more compatible. If acceleration is not available on your device, the app tries Precise mode on its own.

What this tool does not do

  • One video at a time and only MP4, M4V, MOV, WebM, MKV and TS.
  • The compression is lossy; it is not possible to reduce without some quality loss.
  • When you change the screen aspect ratio (16:9, 9:16, 1:1, 4:5) the app resizes without cropping, and the picture may be stretched: keep Keep original if there is no reason to change it.
  • The new file carries the “WebFaz.com” credit in the metadata (comment and artist).

Which level should I choose?
Balanced fits most. Go up to Good quality or High fidelity if the picture matters, and down to Very light or Smallest size if the size limit is tight.
