Frequently Asked Questions
What is WAV format?
WAV (Waveform Audio File Format) is an uncompressed audio format developed by Microsoft and IBM. It stores raw PCM audio data without any lossy compression.
WAV is the standard format for professional audio work, audio CDs (before being converted), and applications requiring exact audio data.
The main drawback of WAV is its large file size — much larger than compressed formats like MP3 or AAC.
Will converting MP3 to WAV improve quality?
No. The lossy compression applied when the original MP3 was created permanently removes some audio data.
Converting to WAV creates a lossless copy of the decoded MP3 audio, but does not restore the removed data.
For best audio quality, always use WAV or FLAC for original recordings.
What is the output WAV format?
The output is 16-bit PCM WAV, the standard format used for audio CDs and compatible with virtually all audio software.
Sample rate matches the original audio as decoded by the browser's Web Audio API.
Both mono and stereo files are preserved in their original channel configuration.
Is my data sent to a server?
No. Conversion uses the browser's Web Audio API entirely on your device.
Your audio files never leave your device. This is safe even for private or copyrighted audio.
We do not store, log, or transmit any audio you convert.
Why is WAV so large?
WAV stores raw uncompressed audio. A 3-minute stereo audio at 44100 Hz and 16-bit depth requires about 32MB of storage.
The same audio as MP3 at 192kbps is about 4MB — roughly 8x smaller.
This size trade-off is worth it for professional audio work where quality and exact bit-accurate reproduction matter.
Can I use the WAV in a DAW?
Yes. The output WAV is standard PCM format compatible with all major DAWs including Pro Tools, Logic Pro, Ableton Live, GarageBand, and FL Studio.
Import the WAV file directly into your DAW's project.
The WAV will import without any transcoding needed.
Does it support stereo audio?
Yes. Both mono and stereo MP3 files are fully supported.
The WAV output preserves the original channel layout (mono stays mono, stereo stays stereo).
Multi-channel MP3 files (rare) will be converted as decoded by the browser.
What if conversion takes a long time?
Conversion speed depends on your device and the length of the audio. Longer files take more time to decode and re-encode.
A 3-minute MP3 typically converts in 5-15 seconds on a modern device.
