About converting Opus to MP3

Converting Opus to MP3 decodes the audio and re-encodes it to MP3 entirely in your browser. MP3 is small and universally playable; WAV is uncompressed and lossless.

Your audio never reaches a server. Converting an already-compressed file to a lossless format can't restore detail that was removed earlier.

Opus is the codec inside voice-chat recordings and WhatsApp voice notes, and almost nothing outside that ecosystem plays it. This converts Opus to a 128 kbps MP3 you can share, archive or drop into any editor — decoded and re-encoded entirely in your browser, so private recordings stay on your machine.

Frequently asked questions

How do I convert Opus to MP3?

Add your Opus file above and press Convert. FileTinker decodes and re-encodes it to MP3 in your browser, then gives you the converted file to download — nothing is uploaded.

Is my audio uploaded to convert Opus to MP3?

No. The conversion runs entirely in your browser, so your audio never leaves your device and nothing is stored on a server.

Will converting change the audio quality?

WAV is uncompressed and lossless, while MP3 uses efficient compression at a high-quality bitrate. Converting an already-compressed file won't restore detail that was removed earlier.

Can I convert several files?

Convert them one after another — each runs locally and downloads instantly, with no queue, sign-up or file-size limit.

Can I convert a WhatsApp voice note to MP3?

Yes — export or save the voice note (they are Opus files) and drop it here; the MP3 plays anywhere. Speech converts to 128 kbps with no practical quality loss, and the file never leaves your browser, which matters for personal messages.
