# Convert WAV to Opus.

> WAV into tiny Opus files — peak efficiency, run locally.

Convert WAV audio to Opus right in your browser — **the most efficient lossy codec in wide use, encoded locally**. Voice recordings collapse from megabytes to almost nothing; music holds up at bitrates MP3 cannot touch.

**No uploads · No ads · Free & open source.**

## How it works

1. Drop files anywhere on the page, click to browse, or paste with Ctrl/⌘ + V.
2. Pick a quality or preset — or set an exact target size and let the tool find it.
3. Compress, compare before/after, and download — individually or as a ZIP.

## What Opus is unreasonably good at

Opus wins listening tests at every bitrate: speech is clean at 32–64 kbps, music rivals higher-rate MP3 at 96–128 kbps. That makes it the right target for voice notes, podcasts, streaming and game audio — WhatsApp voice messages are Opus already. For a lossless archive use [WAV to FLAC](https://compress-pro.com/wav-to-flac); when a legacy player must open the file, [WAV to MP3](https://compress-pro.com/wav-to-mp3) stays the compatibility pick.

## The Opus bitrate ladder

Opus was designed to be chosen by content, not by superstition — each step down the ladder buys real megabytes:

| Content | Bitrate | An hour is roughly |
| --- | --- | --- |
| Voice memo, dictation | 32 kbps | 14 MB |
| Podcast, interview | 48–64 kbps | 22–29 MB |
| Music, everyday listening | 96 kbps | 43 MB |
| Music, critical ears | 128–160 kbps | 58–72 MB |

## Frequently asked questions

### What plays .opus files?

Browsers, VLC, modern phones and every messaging platform. Older car stereos and iTunes-era software may refuse them — MP3 remains the safe pick for legacy gear.

### What bitrate should I pick for voice?

32–64 kbps sounds clean for speech — an hour of voice lands around 15–30 MB. Music is comfortable at 96–128 kbps.

### Is Opus really better than MP3?

At the same bitrate, clearly — especially below 128 kbps, where MP3 degrades audibly and Opus stays composed. That efficiency is why voice platforms adopted it.

### Is it private?

Yes. The audio is decoded and re-encoded entirely in your browser — recordings never leave your device, and the server does nothing but deliver this page. Voice memos, interviews, demos: none of it is uploaded anywhere. Want proof? Run one file through, switch your connection off, and run another — it still works.
