How to convert WEBM to AVI

  1. Open the WEBM

    Drop the .webm file onto the page, or click to choose it from your computer.

  2. Turn it into AVI

    Set the output to AVI and start. VP9 or VP8 video becomes MPEG-4 Part 2, and Opus sound becomes MP3.

  3. Grab the file

    The AVI downloads without a preview, because browsers can't play AVI. Move it to a USB stick for your player.

New web video, older players

WEBM is a modern web format with VP9 or VP8 video, and older TVs and media players were never built to read it. Many of them do play AVI files with MPEG-4 Part 2 video, the kind DivX and Xvid players use, with MP3 audio.

WEBM is always fully converted, and so is every AVI output, so allow some time for long videos. The frame size is kept up to 1920x1080 and frame rates are capped at 60 fps.

Questions and answers

Why won't my older TV play WEBM?

WEBM uses VP9 or VP8 video, which older TVs and players don't read. An AVI with MPEG-4 Part 2 video and MP3 sound is more likely to work.

What codecs does the AVI from a WEBM use?

MPEG-4 Part 2 video, the kind DivX and Xvid players read, and MP3 audio.

Is there a way to check the AVI before I copy it?

Not in the browser, since browsers can't play AVI. Convert a short clip first and test it on your TV or player.

Can I put several WEBM clips into one AVI?

Yes. Add them in the order they should play and they are merged into one AVI file.

Does a WEBM ever skip re-encoding?

No. WEBM is always fully converted, whatever the output format.
