Does it work with M4A files from GarageBand or Apple Music?

Unprotected M4A files (your own recordings and exports) work fine. DRM-protected Apple Music tracks cannot be decoded by any browser tool, including this one.

Is my voice memo kept anywhere after transcription?

No. The file is processed in your browser's memory and is gone when you close the tab. There is no account, no history and no server copy.

M4A to Text Converter

M4A is Apple's house format: every iPhone Voice Memo, every voice note recorded on a Mac, and most audio exported from Apple apps arrives as an M4A file. Those recordings are often personal — bedside ideas, doctor's instructions, family interviews — and sending them to a cloud transcription service feels wrong. TapeToText transcribes M4A files entirely on your device, so a memo recorded on your phone is converted to text without ever being uploaded anywhere.

What people transcribe from M4A

iPhone Voice Memos & Apple recordings — the jobs this format shows up for most.

Voice memo journals

Spoken journal entries and idea dumps become dated, searchable text you can actually revisit — instead of a list of recordings you never replay.

Interview & field notes

Reporters and students recording on iPhone can turn memos into quotable text the same day, with timestamps for fact-checking.

Personal & family recordings

Grandparents' stories, medical instructions and family history interviews stay private — transcription happens on your device, not a stranger's server.

Get a better M4A transcript

The model is the same one the paid services use. The difference between a rough transcript and a clean one is almost always the recording — and a few format-specific habits.

Same privacy promise as every page on this site: your M4A file is processed on your device and never uploaded.

M4A tips from the field

Voice Memos recorded with the phone in a pocket lose high frequencies; if accuracy matters, re-record key passages with the phone on the table, mic unobstructed.
AirDrop or copy the M4A to a computer for long memos — desktop browsers hold larger models in memory more comfortably than phones.
Choose the exact language for memos recorded in Urdu, Hindi or Arabic — auto-detect can wobble on short clips that mix languages.

M4A transcription questions

The things people ask before converting a M4A file.

Open the Voice Memos app, tap the memo, tap the share icon and send it to your computer via AirDrop, email or Files. Then drop the file into TapeToText on any modern browser.
