Supports: WMV
.wmv clips from your device. Batch is supported — every file uses the same settings.Windows Media Video (.wmv) and Windows Media Audio (.wma) both live inside Microsoft's Advanced Systems Format (ASF) container, and according to Wikipedia's WMV article the audio stream inside a WMV file is "typically some version of Windows Media Audio." That makes WMV → WMA the cheapest possible conversion: the encoder can copy the existing audio bytes straight into a new .wma wrapper with no re-encoding and no quality loss. Common reasons people do this:
.wmv concert capture or AMV and keep the WMAv2 track at its original bitrate so the song still sounds like the source..wmv; extracting to .wma gives you a podcast-friendly file that's a fraction of the original size..wmv lectures; WMA extraction preserves the voice track for transcription or accessibility re-use..wma but not modern containers, so WMA stays useful where MP3 or AAC won't decode..wmv (common in PC titles from 2003-2012) can be reduced to .wma for use in mashups, ringtones, or alarm tones.| Property | WMV (input) | WMA (output) |

It depends on the Quality Preset. Leave it on Unchanged and the converter stream-copies the existing WMA track out of the ASF container into a .wma file — same bytes, no quality loss, finished in seconds even on large videos. Switch to a Quality Preset, change the Sample Rate, force Mono, or pick a Custom Bitrate and the audio is re-encoded to WMA v2 at the new settings, which is lossy.
WMA v2 (wmav2, format tag 0x161), the standard lossy codec Microsoft shipped in 1999-2000 and the one decoded by every Windows Media Player install since Windows XP. It supports stereo at up to 48 kHz. If your source WMV already contained WMA Pro or WMA Lossless, the default stream-copy mode preserves that codec — only re-encoding falls back to WMA v2.
.wma almost the same size as the WMV input?Because most of a typical WMV's payload is the audio track plus muxing overhead. If the video stream was low-bitrate (e.g. a 360p screen recording at 200 kbps video + 128 kbps WMA), audio is already a big share of the file, so dropping the video saves less than you'd expect. For a heavy DVD-rip the difference is huge; for a voice-over screencast it can be modest.
.wmv from an old Windows Media store?No. WMV files purchased from Microsoft's old PlaysForSure / Zune Marketplace / MSN Music stores carry DRM that ties playback to a licensed Windows account. xconvert (and every other browser-based converter) cannot decrypt them. You'll get a load error or a silent output. If you legally own the content, play it back through licensed software and re-record locally, or migrate to a DRM-free source.
If your target is a Windows-only environment, an embedded device that explicitly lists .wma, or you want to preserve the original codec losslessly, WMA is fine. For anything else — phones, browsers, smart speakers, modern car infotainment, podcast apps — convert to WMV to MP3 or WMV to WAV instead. MP3 has near-universal hardware support; WAV is uncompressed PCM for editing.
Open Advanced Options, enable Trim, set the Start time and Duration in HH:MM:SS.mmm format. For example Start 00:01:23.500 and Duration 00:00:42.000 pulls a 42-second clip beginning 1 minute 23.5 seconds in. For multi-cut editing after extraction, use the Audio Cutter tool on the resulting .wma.
For spoken word — webinars, lectures, podcasts — drop Audio Sample Rate to 22.05 kHz, force Audio Channel to Mono, and set Custom Bitrate to Constant 48-64 kbps. That cuts file size by roughly 75% versus 44.1 kHz stereo 128 kbps with no audible loss on voice. For music, stay at 44.1 kHz stereo and use 128-192 kbps CBR or VBR.
xconvert processes typical clips without per-file caps for free users. Very large videos (multi-gigabyte HD rips, hour-plus webinars) upload over your browser connection so the bottleneck is usually your upstream bandwidth, not the converter. For huge files, leaving Quality Preset on Unchanged is fastest because the server only has to copy the audio bytes — no transcoding CPU time.
Yes. Add all the .wmv files to the queue in one go (drag a folder onto the upload area or shift-select in the file picker). Every file uses the same settings — handy for ripping an entire training course or concert archive to audio in one pass. Output is a separate .wma per input; pair with Compress WMA afterwards if you need to shrink the lot.
