To convert M4A to text, upload the file to TranscriptX from your device, Google Drive, Dropbox or OneDrive, with no need to convert it to MP3 or WAV first. The AI transcribes the speech and shows punctuated paragraphs with timestamps. Fix any word with Edit, then click Copy, or click Download for a TXT, DOCX, PDF, SRT or VTT file.
An M4A to text converter listens to the speech in an M4A file and writes it out as text. M4A is a compressed audio format that Apple devices use by default: iPhone and Mac voice memos, QuickTime audio recordings and many audio-only exports from meeting and recording apps are saved as .m4a.
Typing up one hour of audio by hand takes about four hours. TranscriptX turns the M4A file into text in seconds to minutes, depending on its length, so you spend your time reading and using the transcript instead of pausing and rewinding.
Click Upload and choose From this device, Google Drive, Dropbox or OneDrive. Upload the M4A as it is; there is no need to convert it to MP3 or WAV first.
TranscriptX detects the language and writes out the speech as paragraphs, each with a timestamp. The recording plays beside the text.
Play the parts you care about, and use Edit to fix names, numbers or terms the audio made hard to catch.
Click Copy to put the text on your clipboard. To save a file, click Download, the button next to Copy, and pick .txt, .docx, .pdf, .srt or .vtt.
TranscriptX is free every day and you can try it without an account. Open the page, upload your M4A file and read the transcript in the same browser tab. There is no app to install, so the M4A to text online converter works the same on iPhone, Android, Mac, Windows and Chromebook.
Sign in to keep your transcripts in History across devices. For long recordings or daily use, the <a href="/pricing/">Pro plan</a> adds a stronger model, speaker labels, noise reduction and unlimited transcription.
No. TranscriptX reads M4A directly, so you can upload the file exactly as your phone or app saved it. Converting it to MP3 only adds a step and compresses the audio a second time, and converting it to WAV makes the file much larger without adding any detail.
M4A files are small for the sound quality they hold, so even a long recording uploads quickly. If the file is already in Google Drive, Dropbox or OneDrive, upload it from there. For very long recordings, see <a href="/transcribe-large-audio-files/">Transcribe Large Audio Files</a>, and check your plan's file size on the <a href="/pricing/">pricing page</a>.
A transcript you can work with, not just a block of words:
Sentences, commas and paragraph breaks are added for you, so the text reads like writing, not a stream of words.
Each paragraph shows where it starts in the M4A file. Turn timestamps on to check a quote against the audio, or off for clean reading text.
On the Pro plan, interviews, meetings and calls with two or more voices come back with each speaker labelled.
Write notes, checklists and timestamped bookmarks in the Notes tab next to the text.
Fix a word, a name or a number directly in the transcript before you copy or export it.
Click Download next to the Copy button and choose the format your next step needs. Use .txt for plain text or another app, .docx to edit in Word, Google Docs or Pages, and .pdf to share or file a read-only copy.
Need subtitles? Download .srt or .vtt to get a subtitle file with timing for each line. If you want subtitles from a video file directly, use <a href="/video-to-text/">Video to Text</a>.
Any M4A file with speech in it. The ones people convert most:
Ideas, lectures, interviews and reminders recorded in Voice Memos are saved as M4A. Save the memo to Files or your Mac, then upload it. To record straight in the browser instead, use <a href="/voice-to-text/">Voice to Text</a>.
Many meeting and call apps can save an audio-only copy as M4A. Upload it and get a written record of what was said and decided.
Interviews recorded on a phone come back as text you can quote. For research and press interviews, use <a href="/interview-transcription/">Interview Transcription</a>.
Recorded lessons become notes you can search by keyword and jump to by timestamp.
Episodes and audio exported as M4A or AAC from an editor. See <a href="/blog/how-to-transcribe-podcast/">how to transcribe a podcast</a>.
M4A compresses audio without much audible loss, so accuracy depends on the recording itself, not on the file format. A clear voice, one speaker at a time and little background noise give a transcript that needs few corrections. Crosstalk, echo, music under the speech and a phone far from the speaker cause more errors.
Before you rely on the text, check names, numbers and technical terms against the audio using the timestamps. On the Pro plan, noise reduction helps with noisy recordings.
Not every recording is an M4A file. TranscriptX also accepts MP3, WAV, AAC, FLAC and OGG audio, and video files such as MP4 and MOV. For MP3 files, use <a href="/mp3-to-text/">MP3 to Text</a>; for WAV, <a href="/wav-to-text/">WAV to Text</a>; for any audio format, <a href="/audio-to-text/">Audio to Text</a>; for video, <a href="/video-to-text/">Video to Text</a>.
Uploaded files are deleted automatically, and your recordings and transcripts are not used to train AI models. You can delete a single transcript, or all your data, at any time from your account. See the <a href="/privacy-policy/">Privacy Policy</a> for details.
