Step 1: Get the Memo Off Your Phone
In the Voice Memos app, tap the recording, tap the share icon (or the three-dot menu, then Share), and send the file to yourself - AirDrop to a Mac, Save to Files (then access it from any browser via iCloud), email, or a messaging app. The shared file is a .m4a. Android voice recorders vary: most save M4A or AAC files to internal storage, reachable from the Files app. Note that mp3.now works on mobile browsers, so you can convert directly from the phone without a computer.
Step 2: Convert to MP3
- Open the M4A to MP3 converter in any browser.
- Upload the voice memo. Most memos are small - a 10-minute recording is roughly 10 MB, right at the guest limit, so a free account (50 MB) helps for longer recordings.
- Choose a bitrate: 96-128 kbps is plenty for speech; there is no benefit going higher than the source.
- Click Convert, then download your MP3.
Several memos? Batch up to 10 files in one pass.
Optional Cleanup Before Sharing
Voice memos are often recorded far from the microphone and start with fumbling. Two quick fixes: trim the dead air and false starts from the beginning and end, and run the file through the normalizer so quiet recordings come up to a comfortable level - particularly worthwhile before sending a memo to a transcription service, where consistent audible speech improves accuracy. For speech, converting stereo to mono also halves the size with no downside.
Privacy Note
Voice memos are often sensitive - meetings, medical notes, personal reminders. On mp3.now, uploads and converted files are deleted automatically after the retention window (24 hours for guests, 7 days for free accounts), and files are never shared or made public. Read the full privacy and security overview if you are handling confidential recordings.
Troubleshooting
The memo will not attach or upload: long recordings sometimes exist only in iCloud until played - open the memo once in the app (or in Files) so it downloads fully, then share again. The file is too large: hour-plus recordings can exceed upload limits; a Premium account accepts up to 200 MB, or split the recording on the phone first using the Voice Memos edit function. The shared file has a strange name: Voice Memos names files by date and time - rename before or after converting; the audio is unaffected. Playback sounds fine on the phone but the recipient reports silence: their software likely failed on the M4A rather than your recording - sending the converted MP3 resolves it, which is usually the reason you are here in the first place.
