Transcribe an M4A file to text.

M4A is what phones and laptops record. Drop the file here as it is, or pick it on your phone, and get a timestamped transcript and a summary whether it is a two-minute memo or a six-hour day of recordings.

The file you have

Where M4A files come from.

iPhone and Mac
Voice Memos, call recordings saved from Notes, QuickTime Player audio recordings.
Android and Windows
Samsung Voice Recorder and most Android recorders; Windows Sound Recorder.
Meetings
Zoom's local recording folder holds an audio-only .m4a next to the video. It is the smallest file with every word in it.
Typical size
30–60 MB an hour, so even long recordings fit in the box on this page.

Sometimes a link works. Upload the file, or paste a link if it sits in Google Drive ('Anyone with the link') or at a direct address ending in .m4a.

How it works

Three steps, the first one is the only one that takes any thought.

1

Get the file where the browser can see it

On an iPhone, share the memo or recording to Files first. On a computer it is already a file.

2

Drop or pick it

On a phone, tap the box and choose the file. No conversion to MP3 is needed.

3

Read, then export

Free preview and summary; a pack opens the full transcript and every export.

Good to know

What trips people up, and what to do about it.

Example. A researcher records a 1 h 20 min interview in Voice Memos. The 38 MB .m4a is shared to Files and uploaded from the phone; the transcript and the key quotes, each with a timestamp, are ready about three minutes later. Checked 4 October 2026: .m4a and .m4b files uploaded through this site came back as text.

What comes back

More than a wall of text.

The same four things for every M4A recording, whatever its length.

A transcript with timestamps

Every line carries its time. Click a line to hear that second again, or search a name or phrase and jump to each place it was said.

A summary, chapters and key quotes

A brief with the takeaways, chapters with their start times, and the quotes worth keeping. Speakers are identified and named in the summary, key quotes and chapters.

Questions answered from the recording

Ask where a topic came up or what was decided, and get the answer with the time it was said, instead of scrolling the whole text.

Every export

TXT, DOCX, SRT, VTT, JSON from the same transcript: a document to edit, caption files for video, plain text to paste, structured data for your own tools.

Pricing

FAQ

Transcribing M4A files, answered.

How do I transcribe an M4A file?

Drop the .m4a in the box on this page, or tap the box on a phone and pick it. The transcript comes back with timestamps, usually within a few minutes.

Do I need to convert M4A to MP3?

No. M4A is read directly.

Can I transcribe an M4A from my iPhone?

Yes. Share the recording to Files, open this page in Safari, tap the upload box and choose the file.

How is this different from the M4A to text page?

Same engine. That page is the quick converter; this one covers where M4A recordings come from, long recordings and the files that fail.

What does it cost to transcribe an M4A file?

The preview and the summary are free. A pack opens the full transcript: $4 for 500 minutes, $8 for 1,000 minutes, $12 for 2,000 minutes, $24 for 5,000 minutes. Packs are one-time, credits never expire, and Workspace is $19 a month if you transcribe every week.

How long can the recording be?

One file can run up to 10 hours or 5 GB. The box on this page takes files up to 500 MB; a larger file continues on the main upload page, which uploads it in parts. Most recordings come back in about two minutes per hour of audio.

Is the recording kept private?

Recordings are transcribed on our own servers and are never used for training. You can delete a recording and its transcript at any time.
