File extension	.MP3
Category	Audio File
Description	MP3 is the most popular audio file type based on MPEG-1 Layer III compression. Its lossy algorithm was developed in 1991. MP3 codes the sound almost with the same quality, as CD (16-bit stereo), providing compression in size 1 to 10 from the original WAF or AIFF tracks. The quality of MP3 seriously depends on the bitrate. It can be 128 - 256 kbps. Higher bitrates are also supported, but they seriously increase the file size. It is supported by all modern hard- and software players.

Useful tool for pulling MP3 out of WMV files. I converted a whole folder of WMV presentations and all the audio tracks came out great.

Convert WMV to MP3 — Frequently Asked Questions ▼

Does the WMV file need to have audio for this to work?

Yes. The converter extracts the audio track from the WMV file. If the WMV has no audio track, the output MP3 will be empty or silent. Verify the WMV plays audio in a media player before converting.

Will re-encoding the WMA audio to MP3 reduce quality?

Yes — both WMA and MP3 are lossy formats, and converting between lossy codecs causes a small additional quality loss. At 192 kbps MP3, the result is acceptable for most uses. For maximum quality, convert to WAV instead.

My WMV file is from Windows Movie Maker — will it work?

Yes. Windows Movie Maker typically produces WMV files with WMA audio, which is fully supported. The converter extracts the audio and outputs MP3.

Can I play the resulting MP3 on iPhone or macOS?

Yes. MP3 is natively supported on all Apple devices and macOS. WMV does not play on Apple hardware without third-party software, making MP3 conversion the standard workflow.

What is the maximum WMV file size I can upload?

The online converter accepts files up to 50 MB. For larger WMV files, use the desktop Total Audio Converter, which has no file size limit.

How do I batch-convert WMV files to MP3?

Use the desktop Total Audio Converter: TotalAudioConverter.exe C:\wmv_files C:\mp3_out /ConvertTo mp3 /ProcessRecursively

Can I keep only a portion of the audio from the WMV?

The online converter converts the full audio track. To trim the output to specific time ranges, use the desktop Total Audio Converter, which supports start/end time parameters.

What Is WMV?

WMV (Windows Media Video) is Microsoft's proprietary video format, developed in the late 1990s as part of the Windows Media framework. WMV files use the Windows Media Video codec for video and Windows Media Audio (WMA) for audio. WMV was the default output of Windows Movie Maker and is found in corporate training libraries, government media archives, and old PC home videos. It is not natively supported by macOS, iOS, Android, or modern media players without codec packs.

What Is MP3?

MP3 (MPEG-1 Audio Layer III) is the universally compatible audio format supported natively by every operating system, phone, car stereo, podcast app, and streaming platform. Its psychoacoustic compression achieves excellent quality at 128–320 kbps with small file sizes. When you need audio from a WMV file to play on any device or share with anyone regardless of platform, MP3 is the correct output format.
