iPhone
Pick your .opus voice notes, tap Convert, share the MP3 or WAV. Batch mode, works offline, nothing is uploaded.
Turn .opus voice notes into MP3 or WAV files that play everywhere. Pick one file or a hundred, tap Convert, and share the results to Files, Mail, AirDrop or any app.
Everything happens on your iPhone. No upload, no account, no waiting for a server, and it works in airplane mode.
WHY YOU NEED IT
Voice messages from chat apps arrive as .opus files (names like PTT-20260908-WA0012.opus). Most music players, editors, transcription tools, car stereos and older devices cannot open them. This app converts them to MP3 or WAV in seconds.
HOW IT WORKS
1. Long-press a voice note in your chat app, tap Share, then "Copy to Opus to MP3 Converter", or save it to Files and pick it in the app
2. Choose MP3 or WAV
3. Tap Convert, then Share each file
BATCH CONVERSION
• Pick many files at once from Files, iCloud Drive or any file provider
• Convert them all with one tap
• Each result gets its own Share button
INPUT FORMATS
.opus, .ogg, .oga, .m4a, .aac, .mp3, .wav, .caf, .aiff, .flac, .amr, .3gp and more
OUTPUT FORMATS
• MP3 (128 kbps): plays on everything, stays small
• WAV (16-bit PCM): lossless, ideal for editing and transcription
PRIVATE BY DESIGN
• 100% on-device processing
• No internet connection required
• No account, no sign-up
• Your recordings never leave your phone
Free, with no watermarks and no limits. A small banner ad keeps it free; a one-time Remove Ads purchase hides it forever.

New: a one-time Remove Ads purchase. A small banner now keeps the app free; buy Remove Ads once and it is gone for good. Also includes stability fixes.
