Audio to Text: MP3, WAV, M4A, OGG, MP4
Upload a file in any format — MP3, WAV, M4A, OGG, or MP4 video — with no conversion. AI extracts the audio and turns speech into text with timestamps.
Audio and video to text — any format
Transcription to text works with any common audio and video format — you can upload a file as-is, with no conversion first. DictAI accepts MP3, WAV, M4A, OGG, MP4, and other formats directly: the service extracts the audio and recognizes the speech itself. This is handy when a recording came from a messenger, a voice recorder, a video, or was downloaded from a platform — no need to find a converter and waste time re-encoding.
A file's format is primarily a way of packaging the sound, and it has almost no effect on the transcription itself. What matters far more is how clean the recording is: with clear speech and little noise, the AI recognizes the text more accurately regardless of whether it's MP3 or WAV. Compressed formats (MP3, M4A, OGG) take up less space and upload faster, while uncompressed WAV stores audio without loss — for a normal recording the difference in recognition quality is usually unnoticeable.
All formats get the same capabilities: recognition in 35+ languages, timestamps, speaker labels when there are several voices, editing the text in the browser, and export to TXT, DOCX, PDF, and to SRT and VTT subtitles for video. Video (MP4 and others) is processed the same way as audio: the service takes the audio track and turns the speech into text. Links from 1,000+ platforms are supported too — the source format is detected automatically.
Below is how transcription works with the most common formats. If your format isn't listed, it's most likely still supported: the service accepts most common audio and video containers. You can start for free — 30 minutes of transcription with no card required.

Transcription by format
MP3 to text
MP3 is the most common format: podcasts, recorder files, downloaded audio. It uploads directly and is recognized into text with timestamps.
WAV to text
WAV stores audio without compression — typical for studio and high-quality recordings. It's accepted as-is, with no need to re-encode to MP3 first.
M4A to text
M4A is the format of the iPhone voice recorder and Apple app recordings. It uploads directly and is turned into text with speaker labels.
OGG to text
OGG (Opus) is the format of voice messages in messengers. The service recognizes them with no conversion; see the voice-message page for details.
MP4 to text
MP4 is a video format: the service extracts the audio track and turns the speech into text, and makes SRT and VTT subtitles when needed.
