Convert MP3 audio files to WAV format for professional audio editing, CD burning, or compatibility with applications that require uncompressed audio. WAV files preserve full audio quality without the compression artifacts of MP3.
While MP3 is great for storage and streaming, WAV is the industry standard for audio production, broadcasting, and any application where audio quality is paramount.
Customize your WAV output with these settings:
Note: Converting from MP3 to WAV cannot restore audio data lost during the original MP3 compression. The WAV file will be higher quality for editing purposes but won't exceed the quality of the source MP3.
MP3 (MPEG Audio Layer III) is a lossy compressed format that reduces file size by removing audio data that's less perceptible to human hearing. It's widely used for music distribution and streaming.
WAV (Waveform Audio File Format) is an uncompressed audio format developed by Microsoft and IBM. It stores raw audio data without compression, resulting in larger files but perfect audio fidelity.
Converting to WAV won't restore audio data lost in MP3 compression. However, WAV prevents further quality loss when editing and re-saving, making it ideal for audio production workflows.
44100 Hz (44.1 kHz) is CD quality and works for most purposes. Use 48000 Hz for video production. Higher rates like 96000 Hz are for professional audio mastering.
WAV is uncompressed audio, so files are typically 10x larger than MP3. A 5MB MP3 might become a 50MB WAV file. This is normal and expected.
Yes, our converter supports batch processing. Upload multiple MP3 files and convert them all to WAV with the same settings.
