WAV files commonly contain uncompressed PCM audio, which can make them large and inconvenient to share.
This tool encodes your WAV as a 320 kbps MP3. The resulting file is much smaller and widely supported by phones, computers, car stereos, media players, and sharing applications.
MP3 uses lossy compression, so some audio information is permanently discarded. Convert to MP3 when file size and compatibility matter more than retaining an uncompressed source.
The output is a constant-bitrate MP3 encoded at 320 kbps, the highest standard MP3 bitrate. It uses approximately 2.4 MB per minute of audio, although the final file may be slightly larger because of metadata and file overhead.
If you need to reduce the file size without using lossy compression, consider FLAC instead.
Create a smaller copy of a recording for sharing, reduce the space used by voice recordings and demos, or prepare audio for a device or application that works more conveniently with MP3.
The amount saved depends on the WAV file's sample rate, bit depth, and number of channels.
The resulting 320 kbps MP3 uses approximately 2.4 MB per minute. A typical uncompressed stereo WAV can be several times larger.
Yes. MP3 uses lossy compression, which permanently removes some audio information.
The tool encodes at 320 kbps to limit additional compression, but the result is not lossless or identical to the WAV.
The output is encoded as a 320 kbps constant-bitrate MP3. This setting is fixed and does not depend on the source WAV.
For mono or stereo WAV files using a sample rate supported by MP3, the converter keeps the original sample rate and number of channels.
WAV files with more than two channels are converted to stereo. Unsupported high sample rates are resampled to 48 kHz.
Yes, especially if you plan to edit, process, archive, or convert the audio again. Use the MP3 as a smaller copy for listening or sharing.
The converter does not impose a fixed file-size limit. The practical limit depends on the memory and processing resources available on your device. Very large or long WAV files may not complete successfully on every device.
The conversion happens in your browser. Your WAV file is processed on your device and is not uploaded to a server.
