MP3, M4A, AAC, OGG, FLAC and other audio or video files. Files are converted on this device and never leave it.

Why convert MP3 to WAV?

WAV stores audio as uncompressed PCM samples, so editing software, samplers, game engines, telephony systems and CD-burning tools can use it directly without decoding. Converting MP3 to WAV decodes the compressed MP3 and writes 16-bit PCM at the original sample rate. It does not restore detail removed by MP3 compression, but it stops further loss each time you edit and save.

How to use MP3 to WAV Converter

  1. Choose Open File or drop your MP3s (or other audio and video files).
  2. Choose mono if you want half the file size for voice recordings.
  3. Optionally trim to a start and end time.
  4. Select Convert to WAV and download the files or a ZIP.

Common uses

  • Audio editing. Edit and re-save without stacking MP3 losses.

MP3 to WAV facts

  • WAV is lossless but cannot add back what MP3 removed.
  • Expect about 10 MB per minute for stereo 44.1 kHz WAV, roughly 10× an MP3.
  • Mono halves the size and suits speech.
  • For a smaller lossless format, use FLAC instead.

Local conversion vs upload-based converters

Upload services are useful when a device is too slow or a format is very unusual. For everyday conversions, keeping the file local is faster to start and keeps private recordings private.

Example: a voice-over for an IVR

A 40-second MP3 greeting becomes a 1.7 MB mono 16-bit WAV, the format most phone systems accept.

What to expect from the result

Output is 16-bit PCM at the source sample rate. Specific sample rates such as 8 kHz for telephony are not offered. Long files produce large WAVs, held in memory before download.

MP3 to WAV Converter questions

Does converting MP3 to WAV improve quality?

No. It preserves the current quality and prevents further loss during editing, but cannot restore detail the MP3 discarded.

Is this MP3 to WAV converter free and private?

Yes. It is free, with no account, watermark, daily credit or conversion count. Your file is opened by your browser and converted on your device; it is not sent to a conversion server. Closing the tab discards the working copy. Downloaded results stay on your device.

Why is the WAV file so big?

WAV is uncompressed: every sample is stored. A minute of stereo CD-quality audio is about 10 MB.

What bit depth and sample rate is the WAV?

16-bit PCM at the same sample rate as the source, usually 44.1 or 48 kHz.

Can I convert video to WAV?

Yes. Open an MP4, MOV or other video and the audio track is saved as WAV.
