What is an M4A file?
M4A is the audio format Apple devices use by default — every iPhone Voice Memo, most iPad and Mac recordings, and the audio-only files from apps like Zoom are M4A (AAC audio in an MPEG-4 container). It sounds great at small file sizes, which also makes it quick to upload.
There's no need to convert M4A to MP3 or WAV first — upload the file above exactly as it is. The transcription engine reads M4A natively, along with MP3, WAV, FLAC, OGG and most video formats, so whatever your recorder produced will work.
The result is a clean transcript with timestamps and speaker labels that you can edit in the browser and export as TXT, DOCX or SRT.

Frequently Asked Questions
How do I convert an M4A file to text?
Upload the M4A in the box above and the AI transcribes it automatically — typically in a few minutes, with timestamps and speaker labels included.
Do I need to convert M4A to MP3 before transcribing?
No. M4A is supported natively, so upload the original file. Skipping conversion also avoids the quality loss of re-encoding.
Are iPhone voice memos M4A files?
Yes — the iPhone Voice Memos app records in M4A. Share the memo to Files, AirDrop or email, then upload it here.
What other formats can I upload?
MP3, WAV, FLAC, OGG and most video formats like MP4 and MOV work too — the engine extracts the audio automatically.
How long can the recording be?
Free transcription covers a generous daily allowance; multi-hour recordings and higher volumes are part of the paid plan.
How accurate is M4A transcription?
M4A files usually transcribe very well because the format preserves voice quality. Clear recordings reach near-human accuracy in 97+ languages.
Can I summarise the recording afterwards?
Yes — once transcribed, you can generate a summary or key points, and ask the AI chat questions about the content.
