About WMV files
WMV (Windows Media Video) is a video file format developed by Microsoft, designed for efficient compression and smooth playback. It delivers good video quality with relatively small file sizes, making it suitable for online streaming and storage. WMV is widely supported on Windows platforms and compatible with many media players. It is commonly used for presentations, tutorials, and archived video content.
About MP3 files
MP3 (MPEG-1 Audio Layer III) is a widely used digital audio format that compresses sound files with minimal quality loss, making them smaller for easy storage and streaming. Developed in the 1990s, it became the standard for music sharing and portable players. MP3 uses lossy compression to remove inaudible frequencies, balancing file size and audio fidelity. Though newer formats like AAC and FLAC offer better efficiency or quality, MP3 remains popular due to its universal compatibility across devices and platforms.

Batch Convert WMV to MP3 Online

With this convertor, you can easily convert multiple WMV files to MP3 format directly in your browser — completely free. You can also customize the video resolution (width and height) during the conversion.

To access advanced settings, click the Options button in the top right corner. There, you can set the output size for your MP3 files.

Additional Settings:

  • Output Dimension: Set the width and height for the output MP3 file.
  • Encoding Speed:Controls how fast the video is encoded. Faster speeds may result in larger file sizes.
  • Video Bitrate:Set between 1–10,000 Kbps to control the video quality and file size.
  • Frame Rate:Defines the video’s FPS (frames per second). Higher frame rates produce larger files.
  • Audio Bitrate:Recommended range is 16–320 Kbps.
  • Cut Video: Trim the video using a start and end time in HH:MM:SS format. For example, setting 00:00:05 to 00:00:08 will cut a 3-second clip from the video or animation.

    • Before converting, you can choose a folder on your device where the converted MP3 files will be saved. Each WMV file will be automatically saved to your selected folder after it's successfully converted — no manual downloads needed.

    Save All: Once all WMV files are converted, click Save All to instantly save all MP3 files to your selected folder.
