When to Convert
Common scenarios where this conversion is useful

Frequently Asked Questions
WMA and MP3 are broadly comparable in quality at equivalent bitrates. WMA offers slight advantages at bitrates below 128 kbps and integrates more deeply with Windows software. For new audio, AAC or Opus are more modern choices.
Yes. If the AVI contains MP3 audio (common), converting to WMA involves re-encoding between lossy codecs. At high WMA bitrates (192 kbps), the audible quality loss from re-encoding is minimal.
Yes. WMA is Windows Media Player's native format. WMA files open immediately, display full metadata, and integrate into Windows Media Player libraries without any codec installation.
WMA has limited non-Windows support. VLC and some Android devices handle WMA, but iOS and most Linux setups require additional codec installation. For cross-platform use, MP3 or AAC are better choices.
FFmpeg encodes WMA at a high quality bitrate by default, typically 192 kbps. This provides excellent audio quality for music, speech, and documentary content.
WMA supports Windows Media metadata including title, artist, album, genre, and cover art. AVI metadata is minimal, so most tags will be empty in the WMA — use Mp3tag or Windows Media Player to fill them in after conversion.
Yes. ChangeThisFile is completely free. No signup, no limits, and no fees.
Standard WMA encodes to stereo. If the AVI contains surround audio (AC-3 5.1, for example), FFmpeg will downmix to stereo for WMA output. WMA Pro supports multi-channel, but it is not commonly used.
Very fast — typically just seconds. Only the audio is processed; the video is discarded, making this much faster than full video transcoding.
Yes. All uploads use HTTPS encryption and files are deleted from our servers immediately after conversion. We never retain or access your content.
