How to convert WEBM to AVI
- Add your .WEBM file - drop it in the box above or click to browse.
- Convert it to .AVI in a few seconds.
- Download your new .AVI file.
What to expect
- Every WEBM-to-AVI conversion re-encodes both video (to Xvid) and audio (to MP3), so some quality is always lost.
- AVI has a 4 GB file size cap due to the RIFF container format - long or high-bitrate videos may hit this limit.
- Subtitles embedded in the
.webmsource are dropped in the AVI output; AVI does not support embedded subtitle tracks.
Frequently asked questions
Does converting WEBM to AVI lose quality?
Yes - because VP8, VP9, and AV1 are not supported in AVI, the video must be re-encoded to Xvid or a similar codec. Using higher quality settings reduces the loss but increases file size.
Why is my AVI file larger than the original WEBM?
VP9 and AV1 (used in WEBM) are more efficient codecs than Xvid (used in AVI), so the same video takes more space in AVI at comparable quality.
Should I convert to AVI or MP4?
Convert to AVI only if your target software specifically requires it - MP4 (H.264/AAC) offers wider compatibility, smaller files, and subtitle support.
Can I convert WEBM to AVI without using the command line?
Yes - our free converter above and desktop tools like Freemake Video Converter handle it without any command-line knowledge.
