Skip the old workflowWhy does my M4A file from a field interview mishear technical terms even after multiple retries?
How do I get clean timestamps for editing when the auto-transcriber merges overlapping speech in long lecture recordings?
What do I do when the output splits speaker turns wrong on dialogue-heavy fight scenes with rapid back-and-forth?
Upload, pick languages, and let the AI handle the rest. No software to install.

I'm a journalist and every interview I do lands on my phone as an M4A voice memo. For years, transcription meant either paying $2/minute or sitting with headphones for twice the interview length. Then I found this converter: I drag the M4A in, pick the language, and by the time I've made tea the whole interview is text. Quotes are now accurate — no more 'um' guessing — and I search the transcript instead of scrubbing audio. My editor thinks I hired an assistant.
Supports speech recognition for over 90 languages — no manual language hint needed for most M4A files.
SRT and VTT outputs include precise timecodes aligned to spoken segments in your M4A file.
TXT, SRT, and VTT files download directly without watermarks or forced attribution.
Your M4A file is processed securely on our servers — no audio leaves your browser during upload.
It works on most M4A files, including those with background noise or mild accent variation. Accuracy improves with clear speech; heavily distorted or muffled clips may need light human review before final use of the TXT / SRT / VTT output.
Yes — longer files process after a short pass. Output quality remains consistent, though very long recordings may show minor timing drift in SRT / VTT output due to cumulative alignment variance.
No speaker diarization is applied. The transcript treats all speech as a single stream. For multi-speaker M4A files, you’ll receive continuous text or timecoded lines without speaker labels in TXT / SRT / VTT.
No installation or sign-up is required. Upload your M4A file directly in-browser, select your options, and download the TXT / SRT / VTT output immediately after processing completes.
