Free Online WMV to MP3 Converter
Convert WMV to MP3 — Rescue Audio from Windows-Only Video Files
WMV is a ghost from the Windows XP era. You will find these files lurking on old backup drives, buried in corporate SharePoint folders, and sitting in Windows Movie Maker project directories that have not been touched in a decade. The video inside may not matter anymore, but the audio often does — a recorded lecture, a training narration, a family video soundtrack, an old Skype call. This WMV to MP3 converter extracts that audio and hands you a clean MP3 that works everywhere. The best part: you do not need a Windows machine to do it. Mac, Linux, Chromebook, phone — open a browser, drop the WMV file in, and change WMV to MP3 in seconds. No codecs to install, no media player to configure.

Where WMV Files Come From (and Why They Are Stuck in the Past)
WMV was Microsoft's answer to every video need from roughly 2000 to 2012. It ended up everywhere. Now those files are stranded in a format that most modern systems have moved on from. Here is where people typically find WMV files they need audio from.
Windows Movie Maker Projects
Windows Movie Maker was the default video editor on every Windows PC for over a decade. It exported everything as WMV. School projects, family montages, early YouTube uploads — millions of these videos exist only in WMV format. If the audio track matters to you — a narration, background music you mixed, dialogue from a family event — converting WMV to MP3 pulls it out without needing to reinstall Movie Maker or dig up old Windows software.
Corporate Training and Presentation Recordings
Companies recorded training sessions, onboarding videos, and webinars in WMV throughout the 2000s. Many of these still sit on internal file servers and SharePoint archives. The video quality is often terrible by today's standards, but the spoken content — procedures, instructions, institutional knowledge — is still valuable. Extract the audio from WMV to MP3 and those recordings become portable podcasts anyone in the company can listen to.
Old Webcam and Skype Recordings
Early webcams on Windows saved footage as WMV by default. Skype (before Microsoft acquired it) and MSN Messenger also used WMV for recorded video calls. If you have personal recordings from that era — a conversation with a grandparent, a long-distance call with a friend, a band rehearsal over webcam — the audio can be saved. Convert WMV to MP3 and keep the voices even if the grainy 320x240 video is not worth preserving.
Why This WMV to MP3 Converter Handles What Others Skip
WMV is a format most modern converters treat as an afterthought. This tool was built to actually read the full range of WMV files people encounter in the real world, not just the easy ones.
Opens WMV Files That Mac and Linux Reject Outright
Try double-clicking a .wmv file on a Mac. Nothing happens. Open it on Ubuntu. Same story. WMV is a Windows-only format, and outside of VLC, almost nothing on non-Windows systems reads it natively. This WMV to MP3 converter runs in your browser on any operating system — macOS, Linux, ChromeOS, even iOS and Android. No codecs, no plugins, no workarounds.
Extracts Audio from Windows Movie Maker Projects and Exports
Windows Movie Maker exported everything as .wmv with WMA audio inside. This converter decodes the WMA audio stream from the WMV container and re-encodes it as MP3. The result is a clean audio file from your old movie projects — narrations, soundtracks, voiceovers, event audio — ready to play on any modern device or import into any audio editor.
Converts Corporate Training WMV Videos to Portable Audio
Those 45-minute training WMV files from 2007 are still full of useful information. Rather than forcing employees to sit through low-resolution video, extract the audio as MP3 and distribute it as a podcast-style file. People can listen during commutes, at their desks, or on their phones. Converting WMV to MP3 turns forgotten video archives into accessible audio resources.
Handles WMV Files Embedded in Old PowerPoint Presentations
Older versions of PowerPoint let users embed .wmv videos directly into slide decks. If you have extracted one of those embedded WMV clips and need the audio — a recorded speaker, a narrated demonstration, a product walkthrough — this converter reads it without issues and delivers the MP3 audio track.
Processes Old Webcam Recordings from Early Skype and MSN Messenger
The early days of webcam video calls meant WMV recordings at laughable resolutions. The video is barely watchable, but the audio of those conversations is often priceless. This WMV to MP3 converter extracts the audio cleanly, regardless of how low the original video quality was. A 240p webcam recording from 2005 yields perfectly listenable MP3 audio.
Reads WMV7, WMV8, WMV9, and VC-1 Encoded Files
WMV went through multiple codec revisions over the years. Older files use WMV7 or WMV8 encoding, the majority use WMV9, and some HD-era files use the VC-1 variant. Many online converters choke on the older versions. This tool handles the full range — from that WMV7 file off a Windows 98 backup to a VC-1 encoded Blu-ray rip.
How to Convert WMV to MP3
Even if you have never converted a file in your life, this takes under a minute. Here is how to extract audio from any WMV and save it as MP3.
Drop Your WMV File In
Open videotoaudio.net in any browser — it does not matter if you are on Windows, Mac, or Linux. Drag the .wmv file onto the page. Found a whole folder of WMV recordings on an old hard drive? Add them all at once.
Select MP3 and Set the Bitrate
Choose MP3 as the output format. For spoken content like training videos and recorded meetings, 128 kbps keeps files small and sounds clear. For music or high-quality audio, go with 192 or 320 kbps to get the best result when you convert WMV to MP3.
Save the Extracted Audio
Hit convert. The audio is pulled from the WMV container and encoded as MP3 in seconds — even for long recordings. Download the MP3, share it, load it onto your phone, or grab all files as a ZIP if you processed a batch.

WMV to MP3 — Frequently Asked Questions
What is WMV and why can I not play it on my Mac?
WMV stands for Windows Media Video. Microsoft developed it in the early 2000s as their proprietary video format, and it was the default output for Windows Movie Maker, Windows Media Encoder, and countless webcam and screen recording tools on Windows. Apple dropped WMV playback support from macOS years ago, and Linux never supported it natively. Without installing VLC or a codec pack, a Mac simply does not know what to do with a .wmv file. Converting WMV to MP3 sidesteps the whole compatibility problem by extracting the audio into a format everything understands.
Can I convert WMV files from old Windows Movie Maker projects?
Yes. Windows Movie Maker exported finished videos as .wmv files with WMA audio inside. If you still have those exported files — school projects, vacation montages, tutorial recordings — this converter reads them and extracts the audio as MP3. You do not need Movie Maker installed, and you do not even need a Windows PC. Just drop the .wmv file into the converter from any browser on any operating system.
I found WMV training videos from 2008 at work — can I extract the audio?
Absolutely. Corporate training videos from that era were almost always saved as WMV. The spoken instructions, procedures, and institutional knowledge in those recordings is often more valuable than the dated PowerPoint slides visible in the video. Convert the WMV to MP3 and you get a portable audio file that employees can listen to on their phones, in the car, or at their desks — no need to hunt down a WMV-compatible video player.
Does this handle WMV files embedded in PowerPoint?
Yes, once you extract the .wmv file from the PowerPoint deck. Older versions of PowerPoint (2007 through 2013) commonly embedded WMV clips directly into presentations. You can extract the embedded video by renaming the .pptx to .zip and opening it, or by using PowerPoint's "Save Media As" option. Once you have the standalone .wmv file, drop it into this converter and extract the audio as MP3.
WMV was the standard for Windows webcams — can I convert old recordings?
Yes. Early webcams on Windows — Logitech, Creative, Microsoft LifeCam — all defaulted to WMV for recorded video. The resolution was usually 320x240 or 640x480, but the audio is often surprisingly clear for the era. If you have webcam recordings from old Skype calls, MSN Messenger sessions, or just personal video diaries, convert WMV to MP3 and preserve the audio in a modern, universally playable format.
Why did Microsoft stop using WMV?
Microsoft shifted away from WMV as the industry standardized around MP4 (H.264 and later H.265 video with AAC audio). MP4 offered better compression, broader device support, and was not locked to the Windows ecosystem. By Windows 8, the default camera app was already saving as MP4 instead of WMV. Windows Movie Maker's replacement, the Photos video editor, also outputs MP4. WMV still plays on Windows, but Microsoft themselves no longer produce it as a default format.
Can I convert WMV with Windows Media DRM protection?
No. Some WMV files from the early digital media era — purchased videos, rental downloads, and certain corporate distribution files — were encrypted with Windows Media DRM. This converter cannot process DRM-protected files because the audio data is locked behind encryption. If the file plays normally in Windows Media Player without requiring a license, it is DRM-free and will convert without problems. If it prompts for rights or a license, it is DRM-locked.
My WMV file plays in VLC but nothing else — why?
VLC ships with its own built-in codec library that can decode virtually any format, including all WMV variants. Most other media players rely on the operating system's codec support, and modern versions of macOS, Linux, and even some Windows installations do not include WMV codecs out of the box. VLC is the exception, not the rule. If you need the audio from that WMV file in a format that does not require VLC, convert WMV to MP3 online and the problem is solved permanently.
WMV to MP3 vs WMV to MP4 — which should I do?
It depends on whether you need the video. If you only care about the audio — the speech, music, or soundtrack — convert WMV to MP3. The file will be much smaller and plays on everything. If you need to keep the video content too, convert WMV to MP4 instead, which gives you a modern video format. For most people dealing with old training videos, recorded calls, and Movie Maker exports where the video quality is poor, extracting just the MP3 audio is the practical choice.
Can I convert WMV screen recordings from old Camtasia versions?
Yes. Older versions of Camtasia Studio (particularly versions 5 through 7) exported screen recordings as WMV files by default. If you have tutorial videos, software demonstrations, or recorded presentations from that era, this converter extracts the audio as MP3. The narration and any system audio captured in the recording comes through cleanly. Just drag the .wmv file in and the WMV to MP3 converter does the rest.
