Should you convert OPUS to WAV?

A transcription tool or audio editor can’t read an exported WhatsApp or Telegram voice note and needs plain WAV.

Only when software insists on WAV. It stores the decoded OPUS perfectly, but the detail the OPUS discarded is already gone, so the WAV is bigger without sounding better.

WAV also plays in more places: every computer, audio editor and DAW, and most phones.

OPUS is the most efficient audio codec in common use, especially for speech; WAV is uncompressed, studio-quality audio. Use WAV while editing and for systems that demand it, such as phone systems, samplers and some broadcast tools.

How to convert OPUS to WAV

  1. 01

    Add your OPUS

    Drop your OPUS file onto the box, or click to choose it. It is read from your disk and stays there.

  2. 02

    Check the settings

    The output is already set to WAV. Change the bitrate if you want to; the defaults suit most files.

  3. 03

    Save the WAV

    Press convert and save the WAV. Several files come back together as a ZIP.

What changes when OPUS becomes WAV

Bigger, not better

WAV can’t restore what OPUS compression removed. It does make editing easier and stops further loss, which is why editors and some broadcast systems ask for it.

Expect a much larger file

WAV is far bigger for the same content. Choose it because something needs WAV, not to send or store the file. OPUS: A minute of voice note is often under 200 KB. WAV: About 10 MB a minute at CD quality.

This page is put together from our notes on each format, choosing only what is true of OPUS and WAV, so every pairing states the same facts the same way. How these pages are made.

Why it doesn’t upload

Recordings are often private: interviews, voice notes, unreleased music. Your browser can decode and encode audio itself, so there is no reason to send it anywhere.

How to check for yourself

Worth knowing

  • About the OPUS. WhatsApp voice notes exported from a phone are Opus files, sometimes named .ogg, which many players and transcription services refuse.
  • About the WAV. A WAV made from an MP3 is ten times bigger but sounds exactly like the MP3; the lost detail doesn’t come back.
  • MP3, WAV, M4A, OGG, Opus and FLAC are converted by your browser directly. WMA, AMR, APE, AC3 and the other specialist formats use the FFmpeg engine, a one-time 31 MB download.

Questions
