How to Use the Audio to MP3 Converter
Upload Your Audio Files
First, upload the audio files you want to convert to MP3 format. You can upload in two ways: drag and drop files into the upload area or click to browse and select files. The tool supports WAV, FLAC, OGG, AAC, M4A, WMA, AMR, AIFF, APE and other formats. You can upload multiple files at once for batch processing.

For batch processing, we recommend previewing the audio list first to ensure all files to be converted have been correctly uploaded.
Configure MP3 Parameters
Before converting, you can adjust output settings. Use the bitrate slider to set MP3 compression quality (128kbps-320kbps), select an appropriate sample rate (Auto, 22050Hz, 44100Hz, 48000Hz), and set channels (Stereo, Mono, Auto). If needed, you can also adjust volume or trim audio segments.
192kbps bitrate and 44100Hz sample rate are recommended settings, suitable for most music conversion scenarios.

After configuration, click the "Convert to MP3" button to start processing. The tool will process all uploaded audio files sequentially. For batch processing, a progress indicator will be displayed. Conversion time depends on file size and quantity. Most audio files can be completed within seconds to tens of seconds.
