OPUS to MP3: convert a WhatsApp voice note or a recording
WhatsApp, Signal, Telegram, and many messaging apps record voice notes as OPUS: very compact, but poorly supported outside those apps. Converting to MP3 lets you email the note, drop it into an audio editor, or play it on any device. Current quotas and higher plans are shown on the Pricing page.
Voice quality preserved, slightly larger file
At equivalent quality MP3 is slightly heavier than OPUS on voice. A 200 KB WhatsApp voice note becomes a 400–800 KB MP3 at 96 kbps — still light and workable everywhere. A quick check can prevent problems later. Choose a file, run the conversion, then check the result before downloading it.
Ideal for archiving and transcription
Converting to MP3 helps long-term archival (MP3 will still be readable in 20 years; OPUS is less guaranteed on old systems) and enables direct import into transcription software (Otter, Trint) or AI assistants that don’t always accept OPUS. Keep the original until you have approved the result.
