Is this OPUS to WAV converter really free?

Yes. Up to 5 files at a time, no signup, no catch. The free tier adds a small watermark to image output — Pro ($9.99/mo or $49/yr) removes it, raises the file size limit to 500 MB, and unlocks unlimited batch conversion.

Are my files uploaded to a server?

No — and you can verify it yourself. Open DevTools → Network tab, then convert a file. You'll see zero upload requests. Everything runs right in your browser. We never see your files.

How long does conversion take?

Usually 1–3 seconds for a typical file. The very first conversion on a fresh page load may take 5–20 seconds while the converter engine loads — after that it's instant. Your CPU does all the work locally.

What is the file size limit?

Free: up to 10 MB per file, 5 files per batch. Pro: up to 500 MB per file, unlimited batch. If you're working with large videos or RAW photos, Pro is built for that.

Can I batch convert multiple OPUS files at once?

Yes — drop multiple files at once (or Ctrl/Cmd+click to select them) and they all convert in parallel. Free accounts handle up to 5 files per batch; Pro has no limit.

What bitrate will the converted audio use?

We default to 192 kbps for MP3, 128 kbps for OGG/Opus, and 320 kbps for M4A/AAC. These settings are perceptually transparent — most listeners can't tell the difference in a blind test.

Will my metadata (ID3 tags, album art) be preserved?

Yes, when both formats support it. Tags carry over on conversions like MP3→M4A or FLAC→MP3. WAV has limited tag support, so some metadata may not transfer.

Where do .opus files come from?

Opus is the audio format used by Discord voice messages, Telegram audio messages, WhatsApp voice notes, and many VoIP applications. It's highly compressed for real-time audio.

Can I open a WAV converted from Opus in any audio editor?

Yes. WAV is universally supported by every audio editor — Audacity, GarageBand, Logic Pro, Adobe Audition, and all DAWs accept it without plugins.

How private is this converter?

Completely private — by design, not policy. There is no upload endpoint. Files are processed right inside your browser tab and disappear the moment you close it. We collect only anonymous page-view counts; your file content is never seen or stored.

Why convert OPUS to WAV?

Opus is a modern, highly efficient audio codec used in voice communication applications including Discord, WhatsApp calls, Zoom, and WebRTC-based platforms. However, Opus inside OGG or WebM containers is not widely supported in professional audio software or consumer media players. If you record a conversation through a web browser, download a Discord call recording, or export audio from a WebRTC session, the result is often an Opus file that standard tools refuse to open.

WAV is the format that professional audio tools, consumer media players, and hardware devices understand universally. When you need to edit a recorded Discord conversation in Audacity, clean up a WebRTC call in iZotope RX, or import a voice recording into a podcast project in Adobe Audition, converting Opus to WAV eliminates the format barrier. Windows Media Player, VLC, iTunes, and every general-purpose media player handle WAV without any codec installation.

Converting Opus to WAV decodes the compressed audio into uncompressed PCM data. Because Opus is a lossy codec, some original audio information was discarded during encoding, and the WAV output reflects the quality level of the Opus source rather than the original uncompressed recording. At Opus bitrates above 96 kbps for music or 32 kbps for voice, quality is typically excellent. The WAV output will be much larger than the Opus original, but it opens in every audio application without compatibility concerns.

Quality & file size: OPUS to WAV

Typical file sizes: OPUS 1–3 MB → WAV 30–50 MB.

Both OPUS and WAV use lossy compression. We transcode at high quality settings (equivalent to WAV's recommended web quality) to minimize generational loss.

Color depth: OPUS supports standard color, WAV supports standard color.

Transparency: OPUS does not support transparency. WAV does not support transparency — transparent areas become solid white.
