What is a WMV file?
WMV – Windows Media Video. WMV is Windows Media Video, Microsoft's video format for Windows Media Player and old Windows programs. Converting makes a new file: the video is decoded and encoded again, so converting from a format that lost detail never brings it back.
WMV Converter →What is an M4A file?
M4A – MPEG-4 audio (M4A). M4A is audio (usually AAC or Apple Lossless) in an MP4 file, the format of iTunes, Apple Music and iPhone voice memos. Converting makes a new file: the sound is decoded and written again, so converting from a lossy format never brings back what was lost.

Frequently asked questions
Is converting WMV to M4A free?
Yes. Everyone gets 25 free credits a day, with no account needed. Conversions on our server use one credit per started minute of work, so most cost a single credit. Credits reset at midnight UTC.
Are my WMV files uploaded anywhere?
This conversion runs on our server, because converting video needs ffmpeg, which does not run in a browser. Your file is sent over an encrypted connection, and both it and the result are deleted 72 hours after the conversion. The server has no internet access while it works on your file.
How large can the WMV file be?
Up to 1 GB per file. This conversion runs on our server, which accepts files up to that size.
Will the M4A look the same as the WMV?
Only the sound is kept: the pictures are left out, and the M4A is made from the first sound track.
Can I convert several WMV files at once?
Yes. Add as many files as you like; they are converted one after another, and each one gets its own Download button.
