How do I play a OPUS file in my browser?
+
Drag your OPUS file onto the player or click to upload. OPUS is a lossy compressed format every modern browser can decode, so playback starts instantly with no plugin.
Will playing OPUS reduce its quality further?
+
No. Playback only decodes the existing OPUS stream; it never re-encodes, so no additional lossy generation loss is introduced by listening.
Does the player show OPUS bitrate and metadata?
+
Yes. The player reads the OPUS header and exposes duration, bitrate, and embedded ID3/tags so you can confirm the encode before listening.
Why does my OPUS file sound slightly different from the original master?
+
OPUS is lossy: the encoder discarded inaudible (and some audible) data to shrink the file. The player faithfully reproduces what the OPUS encoder kept — it cannot restore discarded detail.
Can I play a OPUS file gaplessly in a playlist?
+
Queue several OPUS files and they play back to back. Note that lossy formats like OPUS can introduce small encoder-padding gaps that aren't present in lossless sources.
Is my OPUS file uploaded to your servers?
+
No. Your OPUS file is decoded locally in your browser and is never sent to a server.
Does the OPUS player work on phones?
+
Yes. OPUS is universally supported, so the player works on iOS, Android, and desktop browsers alike.
Can I adjust playback speed for a OPUS file?
+
Yes, from 0.25x to 2x. Speed changes are applied during decode and do not alter your OPUS file.
What bitrate should my OPUS files be for good quality?
+
For music, OPUS around 192-256 kbps is a good balance; speech sits comfortably at 96-128 kbps. The player happily decodes any valid OPUS bitrate.
My OPUS file won't play — what's wrong?
+
Confirm the file is a real OPUS stream and not just renamed. Corrupt headers are the usual cause; re-export the OPUS and try again.
Do I need an account to use the OPUS player?
+
No account, no install, no watermark. The OPUS player is free and works immediately.
Can I convert OPUS to another format here?
+
Yes. After previewing, use our converter to turn OPUS into MP3, WAV, FLAC, AAC, and more without leaving the site.
