Convert MP3 to Text Online

Upload an MP3 file and get a word-for-word text transcript with timestamps. Free to start — a one-time 30-minute allowance, no card.

How it works

  1. Upload your MP3 file. Click the upload area or drag your MP3 file directly onto the page. Any bitrate works; free accounts can upload up to 30 minutes and 50 MB per file, Pro up to 4 hours and 500 MB.
  2. Launch the MP3 transcription. Hit Transcribe. DomeScribe decodes the MP3 audio and feeds it into Whisper; the language is detected automatically.
  3. Wait a moment. A five-minute voice memo is usually done in about 30 seconds; longer files take roughly a tenth of their length.
  4. Download or copy the text. Once the transcript is ready, proofread it on screen and export it as plain text (free account). Use it for archiving voice memos, creating written records, or feeding into other tools.

Frequently asked questions

Does the MP3 bitrate affect transcription quality?

Standard bitrates of 128 kbps and above produce the best results. Very low bitrates below 64 kbps can introduce audio artifacts that reduce accuracy, but most MP3 files you encounter will work well in DomeScribe.

Can I transcribe an MP3 recorded on my phone?

Yes. Voice memos and recordings saved as MP3 on your phone can be uploaded directly to DomeScribe. Whisper is trained on a wide range of recording conditions, including mobile microphone audio.

What happens if my MP3 contains only music and no speech?

DomeScribe is designed for speech-to-text conversion. If the MP3 contains only instrumental music, the transcript will either be empty or contain fragments of misrecognized audio. The tool works best with spoken content.

Can I transcribe an MP3 audiobook?

Audiobooks are a great use case because narrators typically speak clearly with minimal background noise. Keep the per-file length limits in mind — 30 minutes on the free plan, 4 hours on Pro, 8 hours on Business — and split long books into chapters.

How do I convert another audio format to MP3 before uploading?

DomeScribe's free in-browser audio converter turns WAV, FLAC, M4A, OGG, or AAC into MP3 without uploading anything. Converting is usually not necessary, though — DomeScribe transcribes WAV, M4A, FLAC, OGG, and AAC directly.
