Video to WMA Converter

How to Convert Video to WMA Online

1. Upload Your Video File: Drag and drop or click "Add Files" to select MP4, MOV, MKV, AVI, WMV, FLV, WebM, 3GP, MTS, M2TS, VOB, TS, MPEG, AVCHD, HEVC, or any of 30+ supported video containers. Batch upload is supported — all files convert with the same audio settings.
2. Pick Quality Preset or Custom Bitrate: Quality Preset offers Highest, Very High, High, Medium, Low, Very Low, and Lowest defaults. For tighter control, switch to Custom Bitrate — Constant Bitrate (CBR) for predictable file sizes from 32 kbps up to 320 kbps, or Variable Bitrate (VBR) ranges like 128k–192k for better quality-per-megabyte. You can also target a specific file size in MB/KB or a percentage of the original.
3. Set Channels, Sample Rate, and Trim (Optional): Audio Channel switches between Original, Mono, or Stereo. Audio Sample Rate ranges from 8000 Hz (voice) through 24000 Hz, 44100 Hz (CD quality), to 48000 Hz (broadcast). Trim lets you set a start time and duration in HH:MM:SS.MS to extract just the segment you need rather than the full audio track.
4. Convert and Download: Click Convert. The video's audio track is demuxed, re-encoded into WMA, and delivered for download — no sign-up, no watermark.

Why Convert Video to WMA?

Pulling audio out of a video file and saving it as WMA strips away the video stream entirely, leaving a much smaller file that plays natively on Windows. Windows Media Audio is Microsoft's proprietary codec family, first released August 17, 1999 with Windows Media Technologies 4.0, and it remains the default audio format for the legacy Windows Media Player ecosystem and the Windows Phone media stack. While AAC and MP3 have largely replaced it for cross-platform use, WMA still earns its place when your destination is a Windows-only workflow.

• Voice memos and lecture recordings on Windows — A 60-minute lecture recorded as MP4 video can be 300–800 MB; the same audio at WMA 64 kbps CBR drops to roughly 28 MB. Windows Media Player, Groove (legacy), and Windows File Explorer's preview pane all open WMA without extra codecs.
• Older car stereos and Windows Mobile devices — Many 2005–2015 head units, factory Sony Ericsson and Nokia phones, and Windows Phone 7/8 handsets ship with WMA decoders but not AAC. Extracting audio to WMA keeps these devices in service.
• Audiobook and podcast archives — WMA at 32–48 kbps mono produces speech-clear files smaller than equivalent MP3, useful for ripping long-form video lectures or sermon recordings into a Windows library.
• Background audio for PowerPoint and legacy authoring tools — PowerPoint 2010–2019 and older Microsoft authoring software embed WMA natively without transcoding, where MP4/MOV audio tracks would force a conversion step.
• Replacing the audio on a WMV — If you're remuxing audio back into a WMV video file, keeping the codec family consistent (WMA inside WMV) avoids re-encoding artifacts and keeps the file fully Windows-Media-Player-compatible.
• Voice-grade ASR and dictation pipelines — WMA Voice and standard WMA at 16 kbps mono 8 kHz are common ingest formats for Windows-native transcription tools and older speech-recognition engines.

Frequently Asked Questions

Will the video's audio sound exactly the same after converting to WMA?

No conversion between lossy codecs is bit-identical. If your source video uses AAC (most MP4/MOV files) or Opus (most WebM files), the audio is being decoded and re-encoded to WMA, which adds one generation of lossy compression artifacts. At 192 kbps or higher these are inaudible to most listeners; at 64 kbps or below on music sources you'll notice softened high frequencies and reduced stereo separation. Use the Highest preset or 256+ kbps CBR for music to minimize generational loss.

Should I pick CBR (Constant Bitrate) or VBR (Variable Bitrate) for WMA?

CBR keeps the bitrate flat throughout the file — predictable file size, simpler to stream, and the safe choice for older car stereos or hardware decoders that can stumble on VBR. VBR (the 128K–192K, 160K–192K style ranges in the dropdown) allocates more bits to complex passages and fewer to silence or simple sounds, giving better quality at the same average size. For Windows Media Player or VLC playback, pick VBR. For unfamiliar hardware, pick CBR.

Why is my converted file silent or shorter than the source video?

Two likely causes: (1) the source video has no audio track — common for screen recordings, GoPro silent mode, and some surveillance footage. The conversion will produce an empty or near-empty WMA. (2) You set a Trim duration shorter than the source. Check the Audio Trim section — if "Unchanged" isn't selected, the start time and duration values are applied. Re-open Advanced Options and set Trim back to Unchanged for the full-length audio.

Can WMA files I create play on iPhone, iPad, or Android phones?

Not natively. Apple's iOS does not include a WMA decoder, and the core Android platform doesn't either — Google removed WMA support from stock Android years ago. You can play WMA on those devices by installing VLC, OPlayer, or another third-party player that bundles its own decoders. If cross-platform mobile playback is your goal, convert to MP3 or convert to AAC instead.

What's the difference between WMAv1 and WMAv2?

WMAv1 is the original 1999 codec; WMAv2 (released with Windows Media Audio 7 in 2000) improves coding efficiency, especially below 128 kbps, and is what virtually every player has supported since the early 2000s. This converter produces WMAv2 by default — there's almost no reason to choose WMAv1 unless you're targeting a specific legacy embedded device that only decodes the original codec.

Can I extract just one chapter or scene from a long video?

Yes — use the Trim controls inside Advanced Options. Set the start time in HH:MM:SS.MS (e.g., 00:12:30.000 to begin at the 12-minute 30-second mark) and a duration (e.g., 00:05:00.000 for a five-minute clip). The converter demuxes only the requested segment, so even a 4-hour source video processes quickly when you only need a few minutes of audio. For more precise multi-cut editing, the audio cutter tool exposes a waveform-style trim interface.

Why is my WMA file larger than I expected for a long video?

WMA file size depends on bitrate and duration, not on the original video's size. A 2-hour movie converted at 192 kbps stereo will land around 173 MB regardless of whether the source was a 1 GB 720p file or a 12 GB 4K file. To shrink it, drop the bitrate (128 kbps for music, 64 kbps for speech), switch from stereo to mono for spoken content, or use a lower sample rate (22050 Hz is enough for voice). The Quality Preset Quick Guide above maps typical bitrate choices to estimated output sizes.

Is WMA still a good choice in 2026, or should I use MP3 or AAC?

WMA makes sense in three specific situations: you're targeting Windows Media Player, you're feeding audio into older Microsoft authoring tools, or you have a hardware decoder (car stereo, voice recorder, Windows Phone) that prefers WMA. For everything else — sharing files, mobile playback, web embedding, archival — MP3 or AAC is the better choice because they're supported on every modern OS and browser without third-party codecs. WMA development has been effectively frozen since around 2009 while AAC and Opus continue to improve.
