How to Convert ASF to MP3 in Bulk Efficiently?

Launch the ASF converter and select Converter among the five modules: Converter, Downloader, Recorder, GIF Maker, Toolbox. Next, click the center + button or the top Add Files to import the ASF videos into the converter. You can also drag all files into the program directly.

On the right side of the interface, click the format image to open the output format list. Go to the Audio section and select MP3 from the profiles below.

After you choose MP3, the program will smart fit the audio settings. But you can hit the Parameter settings tab and continue to modify specific parameters like channels, bitrate, sample rate, or volume based on your needs. Don’t forget to save your changes by hitting Ok.

Finally, click the bottom triangle button to specify an output folder or leave it as default. Then hit the Run button to change ASF to MP3 file type in bulk.

If you don’t want to install third-party software or your disk space is in an emergency, you can try an online converter to complete the conversion. But most web-based services have their own limitations. Take Convertio as an example. It is very easy to use but it is limited to a file up to 100MB. And the unregistered account is limited to process two files at a time. If you just perform video conversion occasionally and the files are small, try online tools. The following are the simple steps:

Step 1. Visit https://convertio.co/;

Step 2. Upload the ASF video you want to convert;

Step 3. Choose MP3 as the output audio format;

Note: You can click the gear-shaped Setting icon to cut and modify the audio parameters for the output MP3 file;

Step 4. Press the Convert button to start conversion and download the converted files.
