Free online WEBM to AVI converter
Create an AVI copy from a WEBM video.
Fileverses processes WEBM uploads sequentially to make a new AVI with MPEG-4 Part 2 video and MP3 audio only when the source has audio.

Supported files
WEBM in. Newly encoded AVI out.
WEBMAVI
The profile uses the first video stream and an optional first audio stream. It encodes them anew rather than only changing the container.
How it works
Convert WEBM to AVI with known boundaries.
Start sequential conversion
Each file is processed one at a time with the fixed AVI encoding profile.
Test the AVI result
Download each separately named AVI and confirm it in the legacy player or workflow that needs it.
AVI output facts
One video stream and optional audio.
The result uses fixed MPEG-4 Part 2 and conditional MP3 settings. Metadata, chapters, subtitles, attachments, and alternate tracks are removed.
Convert WEBM to AVIFirst video and optional first audio
Only the first video stream is mapped, plus the first audio stream if present. Video-only sources produce video-only AVI output.
Fixed legacy-oriented codecs
The route writes MPEG-4 Part 2 video at quality setting 5 and MP3 audio at quality setting 4 when audio exists; it is not a remux.
No source structure preservation
Metadata and chapters are removed. Subtitles, attachments, alternate tracks, and original codec data are not retained.
No tuning controls
There are no trim, resize, bitrate, codec, quality, or stream-selection controls. Input must be a readable non-empty WEBM of 100 MB or less.
WEBM to AVI help
AVI conversion questions.
Which codecs are in the AVI?+−
The profile encodes MPEG-4 Part 2 video at quality 5 and adds MP3 audio at quality 4 only when source audio exists.
Can a silent WEBM be converted?+−
Yes, if it has a readable video stream. Its AVI result will not contain audio.
Is this a container-only WEBM to AVI conversion?+−
No. Video and any mapped audio are re-encoded with fixed codecs and settings.
Does it retain every track or subtitle?+−
No. It uses only the first video and optional first audio stream; subtitles, attachments, alternate tracks, metadata, and chapters are removed.
Can I choose AVI quality or dimensions?+−
No. The encoding profile is fixed and this route has no trim, resize, bitrate, codec, quality, or stream controls.
What files can I upload?+−
Use a non-empty .webm up to 100 MB that host FFmpeg can read and that contains video.
Will every player support the AVI?+−
Compatibility is not guaranteed. Test the new AVI in the specific destination application.
