Launch the software and open the Converter module.

Click + Add File or Add Video Folder to import the H264 files you want to convert. Or you can directly drag and drop the files into the program.

🔔 Note: If you fail to import a file, check if it’s corrupted or DRM-protected first.

Expand the output option list on the right and click the Audio tab, select MP3.

For users with advanced needs, you can open Parameter settings and adjust the audio settings including channels, bitrate, sample rate, and volume. For example, to preserve the best quality, use 320kbps for MP3 bitrate.

If you’re not familiar with these parameters, it’s okay to leave them as Smart-Fit and the program will use common settings based on the format selected.

Click the ▼ button at the bottom to specify an output folder and make sure it has sufficient space for the output file. At last, click the Run button to start the conversion process.

💡 Tip: Before conversion, you can use the trim tool below the video to trim the file if you want.

Video-to-audio conversion should be fast with the program. After conversion, you can view the converted file in the output folder you just set. Note that the original file won’t be deleted.

The program can also help make your file into an H264 video with MP3 audio to fix audio playback problems. Simply follow steps 1 – 3 above, then open the output format list and select MP4 (most recommended due to its widespread popularity), MOV, or MKV as the output format.

Next, open Parameter settings and select H264 as the video encoder and MP3 as the audio encoder. Don’t forget to click Ok to save the settings.

Finally, repeat step 5 to begin the conversion.

If you have a small H264 file under 50 MB, you can use Zamzar to convert it to MP3 for free.
