Voice notes to PDF

Upload MP3, WAV, M4A, or record straight into your mic. Speech-to-text runs on the server, then you get a formatted PDF you can search, email, or archive. Good for meeting notes, interview recordings, or voice memos you'd rather read than replay.

Formats and languages

MP3, WAV, M4A, OGG, FLAC, and WMA all work. Pick the language that matches the recording, wrong language = garbled transcript. English, Spanish, French, German, Italian, Portuguese, Japanese, and Chinese (Simplified) are supported.

Getting usable transcripts

  • Quiet room beats a noisy café, background chatter kills accuracy
  • One speaker at a time is easier than four people talking over each other
  • WAV or a high-bitrate MP3 beats a low-quality phone recording
  • Always skim the PDF before you send it, names, acronyms, and jargon often need a quick fix

Expect roughly 85–95% accuracy on clear speech. Accents, crosstalk, and mumbling will need manual cleanup on anything important.

Your audio on our server

Upload is over HTTPS. We transcribe on our server using offline speech recognition (no third-party audio API). Files are deleted within an hour. Do not upload confidential recordings unless you are comfortable with that.

Up to 50 MB per file. Split longer recordings into parts if you hit the limit.

Yes. You upload the file to our site and we process it on the server. Transcription itself runs offline on our machine, but you need a connection to upload and download.
