AVI to WMA Converter
Convert AVI to WMA online for free and extract audio from video. Use this converter for music tracks, lectures, interviews, podcast source files, and listening without the video stream.
Converting AVI to WMA extracts the audio track from the video and discards the visual frames. The result is typically 80–95% smaller than the source AVI file and is suited for music players, podcast apps, or further audio editing.

Extract audio from AVI into a clean WMA
Pulling the soundtrack out of a video means dropping every video frame and keeping only the audio stream — smaller file, listen-only content.
-
1
Upload your AVI file
Files up to 10 MB on the free plan, up to 1 GB on Pro — enough for lecture recordings, music videos, podcast video versions, and screen captures. Long videos (hour-plus) need Pro because the audio track alone can push past the free ceiling.

Pick the audio quality
For voice content (interviews, lectures, podcasts), 128 kbps WMA is more than enough. For music, aim higher — 192 kbps for casual listening, 320 kbps if you want transparency to the source. The source can't go higher than it already is; if the video's audio was already 128 kbps AAC, exporting at 320 kbps just makes a bigger file.

Convert and download
Extraction is fast — a 30-minute video typically produces its WMA in a few seconds. Both the video you uploaded and the extracted audio are permanently deleted from our servers within 30 minutes.
What actually happens under the hood
A AVI container holds separate video and audio streams. Extraction reads the audio stream, re-encodes it (or copies it, if the target codec matches) into your chosen WMA container, and throws away the video entirely. Metadata like title and track info carry over where the format supports it.
Things worth knowing
- The audio can't be better than the source. Exporting to a high bitrate doesn't recover fidelity — it just wraps the same audio in a bigger file.
- Videos can have multiple audio tracks. Some containers hold dubs, commentary, or 5.1 surround alongside stereo. The default picks the first (usually main) track; the tool page shows a selector when there's more than one.
- Silent video → empty audio. If the source has no audio track, the extraction produces a valid but empty WMA. Check the source has sound before running the tool.
- Copyrighted content still applies. Extracting audio from a video doesn't change who owns the content. Use it for content you have rights to.
When pulling audio out of AVI is the actual job
Six scenarios where extracting audio to WMA solves a real problem.
Turning a lecture recording into a podcast
A recorded lecture, webinar, or class captured as AVI carries hours of good audio and a static talking head. Extracting to WMA produces something you can listen to on a commute — much smaller, playable on any audio app.
Saving a music video's audio for your library
For music videos of tracks you own, extracting the WMA lets you add the song to your regular listening rotation without needing to keep the video around. (Do keep an eye on rights — extraction from third-party sources isn't a licence.)
Publishing a video interview as an audio-only version
Recording a video interview and then distributing the audio-only version to podcast platforms is standard practice. Extracting to WMA gives you the podcast episode without touching the video edit.
Sending audio to a transcription tool
Whisper, Otter, and every other transcription service accept audio directly. Uploading video wastes bandwidth and, in some cases, is rejected outright. Extract to WMA first, upload, get the transcript back in a fraction of the time.
Prepping a ringtone or sound effect
Sound effects and short clips extracted from videos become WMA files ready to import into audio editors, DAWs, or ringtone makers. Video is unnecessary baggage for these use cases; extracting saves the round-trip.
Archiving without the storage overhead
A 1 GB AVI lecture recording carries maybe 60 MB of actual audio. If the video track is disposable — say, a talking head — extracting to WMA cuts storage by 90% while preserving the content that matters.

About the AVI Format
AVI (Audio Video Interleave) is a multimedia container format introduced by Microsoft in 1992 as part of its Video for Windows technology. It is one of the oldest video container formats still encountered today. AVI uses a straightforward structure where audio and video data are interleaved — stored in alternating chunks — allowing simultaneous playback of both streams. Its simplicity made it a dominant format throughout the 1990s and early 2000s.
While AVI benefits from broad legacy support and a simple, well-understood structure, it lacks many features expected in modern video formats. It has no native support for streaming over the internet, cannot embed modern subtitle formats or chapter markers, and its compression efficiency depends entirely on the codec used. AVI files also tend to be larger than equivalent MP4 or MKV files. The format is being gradually replaced by MP4 and MKV in virtually all use cases, though it still appears in older video archives and some legacy industrial systems.
