WMV to MP3 Converter

WMV is a Windows Media format that stopped being convenient years ago — Macs, phones, and most editors will not touch it. Drop a .wmv here and the audio comes back as an MP3, converted right in this page without uploading anything.

仕組み

Add your WMV file

Drop the .wmv above. Files from Windows Movie Maker, old PowerPoint recordings, and Windows camcorder software all work.

Choose a bitrate

WMA audio in WMV files is usually modest quality, so 128 or 192 kbps is generally the right choice.

Download your MP3

Preview it in the page, then save. Your file stayed on your computer the whole time.

主な機能

このwmv to mp3が際立つ理由。

Decodes Windows Media Audio

WMA and WMA Pro tracks are decoded properly, which is the part most non-Windows software cannot do at all.

Works on a Mac

macOS dropped WMV support long ago. This page runs in Safari or Chrome and needs no Flip4Mac or Windows Media plugin.

No upload and no size limit

Old recordings can be large. Nothing is uploaded, so there is no cap and no waiting on a progress bar.

Rescues archived material

Corporate training videos, recorded webinars, and lecture archives from the Windows Media era become usable audio again.

Private and offline-capable

Conversion runs locally, and the converter is cached after the first visit so it works without a connection.

Same conversion via API

Migrating a whole archive? POST each file to /v1/convert/audio instead of doing it by hand.

ユースケース

このツールが時間を節約する一般的なシナリオ。

Old webinar and training archives

Organisations recorded years of sessions as WMV. Convert to MP3 so they can be listened to and transcribed today.

PowerPoint recordings

Older PowerPoint versions exported narrated slideshows as WMV. Keep the narration as audio.

Windows Movie Maker projects

Recover the soundtrack or voiceover from finished WMV exports without the original project file.

Playing WMV audio on a phone

Neither iOS nor Android plays WMV out of the box. MP3 plays on both without any app.

Preparing files for transcription

Transcription services almost never accept WMV. Convert first, then upload the MP3.

Bulk archive migration

Convert a shared drive full of legacy WMV recordings through the API in one pass.

APIで自動化

同じツールをプログラムで使用。HTTPのみで、あらゆる言語で動作します。

cURL

curl -X POST https://api.parsejet.com/v1/convert/audio \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -F "[email protected]" \
  -F "output_format=mp3" \
  -F "bitrate=128k" \
  -o webinar.mp3

Python

import httpx

with open("webinar.wmv", "rb") as f:
    resp = httpx.post(
        "https://api.parsejet.com/v1/convert/audio",
        headers={"Authorization": "Bearer YOUR_API_KEY"},
        files={"file": f},
        data={"output_format": "mp3", "bitrate": "128k"},
        timeout=300,
    )

with open("webinar.mp3", "wb") as out:
    out.write(resp.content)

JavaScript

const form = new FormData();
form.append("file", wmvFile);
form.append("output_format", "mp3");
form.append("bitrate", "128k");

const res = await fetch("https://api.parsejet.com/v1/convert/audio", {
  method: "POST",
  headers: { Authorization: "Bearer YOUR_API_KEY" },
  body: form,
});
const mp3 = await res.blob(); // audio/mpeg

よくある質問

How do I convert WMV to MP3?

Drop the .wmv file above, pick a bitrate, and click Convert. The Windows Media audio is decoded and re-encoded as MP3 inside your browser — no upload, no Windows required.

Can I convert WMV to MP3 on a Mac?

Yes. macOS has not supported Windows Media natively for years, and Flip4Mac is long gone, but this page runs in the browser and does the decoding itself. Nothing to install.

Why will nothing play my WMV file?

WMV is a Microsoft container, and support for it has been removed from most modern players, phones, and editors. Converting the audio to MP3 gives you a file that plays everywhere.

Is WMA audio supported?

Yes. WMV files normally contain WMA or WMA Pro audio, and both are decoded and converted. Files protected by Windows Media DRM cannot be converted by any tool.

Will the audio quality drop?

Marginally, since re-encoding one lossy format to another always costs a little. WMA in old WMV files is typically 64–128 kbps, so converting at 128 or 192 kbps preserves everything audible.

Is it free?

The browser converter is free with no limits. The API for automation is free for 300 credits per month, with paid plans from $19/month.
