Ready for any player, editor, or transcription service.
iPhone Voice Memos, and most Apple audio, come out as .m4a — a fine format that half the world's players, editors, transcription services and car stereos still treat as a stranger. MP3 is the passport format. This tool converts on your device with LAME at high quality.
Voice recordings are often the most sensitive files people own — interviews, meetings, medical notes. Converting them shouldn't mean uploading them. Here it doesn't.
Free, private, no upload. Ever.
This tool runs entirely on your device. It's built by the team behind RenameTo for Mac — where the same job is just a rename in Finder.
