WMA File

File extension .WMA
CategoryAudio File
DescriptionWMA is a very common and widely spread audio file extension, being only second to MP3. It is regarded as an ultimate competitor for MP3, since it almost pars in sound quality with MP3 at comparable bitrates. WMA Pro is viewed as a professional version of WMA Standard, since it uses an advanced multichannel encoding pattern. Today, WMA Pro is on the way toward getting the status of a standard format for next generation DVD. WMA Lossless was designed for storing and archiving audiodata. WMA Voice is a low-bitrate version of the WMA codec used for storing speech data.

MP3 File

File extension .MP3
CategoryAudio File
DescriptionMP3 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.

WMA to MP3 Converter — Frequently Asked Questions ▼

WMA is Microsoft's proprietary audio format that doesn't play on iPhone, iPad, most Android apps, modern car stereos (2015+), or any audio editor like Audacity, Logic Pro, or Ableton. MP3 plays on every device, every operating system, and imports into every DAW. Converting WMA to MP3 fixes the entire compatibility problem in one step.
Both WMA and MP3 are lossy formats, so a small quality reduction occurs at every transcoding step. At the standard 192 kbps MP3 output, the difference is not audible on typical playback equipment. If you need archival quality, convert to WAV or FLAC instead — both are lossless. For music ripped from CD as WMA Lossless, converting to FLAC preserves full audio fidelity.
Yes. WMA stores metadata in ASF object fields — artist, album, title, track number, year, genre. The converter reads these and writes equivalent ID3v2.3 tags to the output MP3. Album artwork embedded in the WMA file is also copied across. Your music library opens in iTunes / Apple Music / Spotify desktop with all the song details intact.
The online converter outputs MP3 at 192 kbps constant bitrate — a good balance between file size and audio quality for music playback. For higher quality (320 kbps) or variable bitrate (VBR) output, use the desktop Total Audio Converter, which exposes full bitrate, sample rate, and channel control.
The online converter accepts WMA files up to 50 MB. Most individual songs and short audio recordings are well under this limit. For long-form WMA audio (audiobooks, podcasts, lecture recordings) and for batch converting an entire WMA music library, use the desktop Total Audio Converter — no file size limit.
Yes. The converter handles all WMA variants: WMA Standard (lossy), WMA Pro (higher bitrate lossy), WMA Lossless, and WMA Voice. WMA Lossless content is decoded perfectly to PCM and then re-encoded as MP3. For preserving WMA Lossless quality without any audio loss, the desktop converter can output FLAC instead of MP3.
The online converter handles one file at a time. For library-wide conversion — moving a Windows Media Player CD-rip collection to iTunes or Apple Music — use the desktop Total Audio Converter: TotalAudioConverter.exe C:\Music\*.wma /mp3 /out C:\MP3\. Add /subfolders to process nested album directories and /keepTags to preserve all ID3 metadata across the entire batch.
 

 

Convert WMA to MP3 — Free Your Windows Media Audio Library

WMA (Windows Media Audio) is Microsoft's proprietary audio format from the Windows XP / Media Player 9 era. If your music library, podcast archive, or audio book collection is in WMA, you've probably noticed: it doesn't play on iPhone, doesn't play on most Android apps, doesn't play on car stereos without WMA codec support, and doesn't import into Audacity, GarageBand, or modern DAWs. Converting WMA to MP3 fixes the entire compatibility problem in one step — every device, every player, every editor opens MP3 natively. Drop your .wma file above and download a standard MP3 in seconds.

What Is a WMA File?

WMA (Windows Media Audio) is Microsoft's audio compression format introduced in 1999 as a competitor to MP3. It comes in several variants: WMA Standard (lossy), WMA Pro (higher bitrate), WMA Lossless (no compression), and WMA Voice (low-bitrate speech). All use the ASF (Advanced Systems Format) container with the .wma extension. WMA was the default ripping format in Windows Media Player on Windows XP, Vista, and 7, which is why so many legacy CD-ripped libraries exist in this format.

Modern devices have moved away from WMA. iPhone, iPad, and macOS have no native WMA support. Most Android phones decode WMA in some apps but not others. Car stereos manufactured after 2015 typically dropped WMA from their firmware. Audacity, Ableton, Logic Pro, and FL Studio do not import WMA. The format is effectively a Windows-only legacy at this point — making conversion to MP3 essential for any cross-platform listening or editing.
