Compress WAV to OPUS for Smaller File Sizes
Massive file sizes (10 MB per minute at CD quality) make it impractical for streaming or casual sharing. Converting to OPUS gives you a key advantage: best-in-class quality at every bitrate from 6 kbps voice to 510 kbps music, with only 2.5 ms codec latency — unmatched by any other codec. OPUS is best for real-time voice communication, live streaming, and low-latency audio where quality at low bitrates is critical.
Why Convert WAV to Opus?
Massive file sizes (10 MB per minute at CD quality) make it impractical for streaming or casual sharing — converting to OPUS overcomes this by providing best-in-class quality at every bitrate from 6 kbps voice to 510 kbps music, with only 2.5 ms codec latency — unmatched by any other codec
OPUS is the right choice when you need to: powering real-time voice chat in discord, whatsapp, and webrtc applications
Gain broader compatibility — OPUS works with WebRTC (all browsers), Discord, WhatsApp, Signal, VLC, Firefox, Chrome, Android; limited iOS support
Reduce file size dramatically — 10 MB – 100 MB per minute files compress to 1 MB – 8 MB per song with OPUS

How to Convert WAV to Opus
Upload your WAV file
Drag your .wav file onto the upload area or click to browse. We accept WAV files up to 500 MB.
Choose OPUS as output format
Select .opus (Opus Interactive Audio Codec) from the format list. Adjust quality settings if needed — higher quality means larger file size.
Convert and download
Click Convert and wait for processing. Your OPUS file will be ready to download in seconds. The result is optimized for real-time voice communication, live streaming, and low-latency audio where quality at low bitrates is critical.
Frequently Asked Questions
Will I lose quality converting WAV to OPUS?
expand_more
Yes — OPUS uses lossy compression, which discards some data to achieve smaller files. Limited native support on Apple platforms (no native iOS/macOS playback) and not yet widely adopted for music distribution. For most practical purposes at high quality settings, the difference is imperceptible.
How large will my OPUS file be compared to the original WAV?
expand_more
WAV files are typically 10 MB – 100 MB per minute, while OPUS files are typically 1 MB – 8 MB per song. The actual size depends on content complexity and any quality settings you choose.
What software can open the converted OPUS file?
expand_more
OPUS is compatible with: WebRTC (all browsers), Discord, WhatsApp, Signal, VLC, Firefox, Chrome, Android; limited iOS support.
What is the maximum file size I can convert?
expand_more
PureConverter accepts WAV files up to 500 MB. Your files are processed securely and deleted from our servers after conversion.
What's the difference between WAV and OPUS?
expand_more
WAV (Waveform Audio File Format) is best for professional audio production, recording studios, and sound design where zero quality loss is mandatory. OPUS (Opus Interactive Audio Codec) is best for real-time voice communication, live streaming, and low-latency audio where quality at low bitrates is critical. Key tradeoff: WAV's advantage is completely uncompressed pcm audio — the raw digital representation of sound with no processing or quality loss whatsoever, while OPUS's advantage is best-in-class quality at every bitrate from 6 kbps voice to 510 kbps music, with only 2.5 ms codec latency — unmatched by any other codec.
Pro Tips for WAV to Opus Conversion
For the best OPUS quality, start with the highest-resolution WAV source available — lossy compression works better with more data to analyze
Keep a backup of your original WAV file — while our conversion is reliable, having the source is always recommended
OPUS works especially well for: storing voice recordings with maximum clarity at minimal file sizes
Did you know? Opus beat every other codec in the 2014 IETF listening tests at every tested bitrate — it was so dominant that the IETF made it a mandatory-to-implement codec for WebRTC, meaning every browser must support it.
