About This Tool
MP3 is the most popular compressed audio format, but many audio editors, DAWs, and CD burning applications require uncompressed WAV files. WAV (Waveform Audio File Format) stores audio in raw, uncompressed PCM format — the same quality used on audio CDs (16-bit, 44.1 kHz). Converting MP3 to WAV is essential for audio editing, music production, and any workflow that needs uncompressed input. Note that converting MP3 to WAV will not restore audio data lost during the original MP3 compression — it simply re-wraps the audio in an uncompressed container. All processing happens directly in your browser using WebAssembly technology for complete privacy.
Frequently Asked Questions
Does converting MP3 to WAV improve audio quality?
No. Converting MP3 to WAV creates an uncompressed file, but it cannot restore audio data that was removed during the original MP3 encoding. The WAV will sound identical to the source MP3.
Why would I convert MP3 to WAV?
Many audio editors (Audacity, Pro Tools, Logic Pro), CD burning software, and professional workflows require WAV input. WAV is also needed for lossless archival and further audio processing without additional compression artifacts.
How much larger will the WAV file be?
WAV files are significantly larger than MP3. A typical 5 MB MP3 file will produce a WAV file around 50 MB, roughly 10 times larger, because WAV stores uncompressed PCM audio data.
What sample rate and bit depth does the WAV output use?
The converter preserves the sample rate and channels from the source MP3 and outputs standard 16-bit PCM WAV, which is compatible with virtually all audio software.
Are my audio files secure during conversion?
Yes! All conversion happens locally in your browser using FFmpeg WebAssembly. Your audio files are never uploaded to any server, ensuring complete privacy.
