Audio and video to transcript converters
Transcribing a supported public platform link rather than uploading a media file? Browse platform-to-format exports.
Conversion means converting spoken words into a text or timed subtitle document. It does not change the underlying audio/video format or add subtitles to video frames.
Free accounts have 60 minutes across 20 jobs monthly, subject to limits. Without an account, a shortened preview may be all you get. Review important quotations before using a transcript.

MP3 audio conversions
For compressed MP3 recording: interviews, lecture audio or a saved podcast. Low-bitrate MP3 artifacts may hide consonants and quiet voices.
M4A audio conversions
For M4A audio container: Apple Voice Memos, phone interviews or meeting recordings. M4A is a container: the audio codec inside still needs to be decodable.
AAC audio conversions
For raw AAC recording: a saved mobile audio recording or exported AAC speech clip. AAC audio can use different profiles; DRM and unsupported codecs will fail.
WAV audio conversions
For WAV recording: field interviews, studio speech or an exported recorder file. Uncompressed WAV files may be large; file size and job limits still apply.
FLAC audio conversions
For lossless FLAC recording: archived spoken-word audio, lectures or an interview master. Lossless sound does not correct microphone clipping or inaudible speech.
OGG audio conversions
For OGG audio container: an Ogg Vorbis or Opus voice recording. OGG is a container, so decoding depends on the actual audio codec.
OPUS audio conversions
For Opus voice recording: a speech note or an exported chat voice message. Very short or aggressively compressed notes can lose words.
OGA audio conversions
For OGA Ogg audio recording: a voice note saved with the OGA extension. The codec must be supported; OGA does not guarantee clean speech.
WMA audio conversions
For Windows Media Audio recording: older Windows voice memos or lecture archives. Protected WMA/DRM content may not decode; this does not remove protection.
AIFF audio conversions
For AIFF audio file: a voice recording exported from an audio editor. AIFF is often uncompressed and may exceed the quick upload size.
AIF audio conversions
For AIF (AIFF) audio file: a legacy Mac audio recording or spoken-word edit. AIF is an alternate AIFF extension; sample quality still matters.
MP4 video conversions
For MP4 video with a speech soundtrack: recorded presentations, video interviews or lectures. The transcription uses the audio track, not text shown in video frames.
M4V video conversions
For M4V video recording: a saved Apple video recording or lecture. Protected or DRM-encrypted M4V files cannot be unlocked by transcription.
MOV video conversions
For MOV QuickTime recording: iPhone camera interviews, meetings or screencasts. A MOV file may be large and may contain codecs the decoder cannot read.
WEBM video conversions
For WebM video recording: browser recordings, screen captures or online presentations. Screen text and graphics are not transcribed; audible speech is.
MKV video conversions
For Matroska (MKV) video: saved webinars, interviews or a video archive. Multiple audio tracks can make choosing the intended spoken track difficult.
AVI video conversions
For AVI video recording: legacy camera recordings, meeting archives or interviews. Some legacy AVI codecs may not decode even though the extension is accepted.
FLV video conversions
For Flash Video (FLV) recording: an archived older web video containing speech. The old FLV container can carry codecs that need conversion first.
WMV video conversions
For Windows Media Video (WMV) file: an older Windows presentation or video meeting archive. Protected media and unsupported Windows codecs cannot be bypassed.
MPEG video conversions
For MPEG video file: a lecture, interview or older camcorder recording. Audio-track quality and codec compatibility determine the transcript.
MPG video conversions
For MPG video recording: a saved older camcorder or presentation file. An MPG recording without audible speech does not yield a transcript.
3GP video conversions
For 3GP mobile-phone video: an older phone interview or mobile video note. Very low-resolution phone video often has equally poor recorded audio.
TS video conversions
For MPEG transport-stream (TS) recording: a broadcast capture or segmented lecture video. Incomplete transport streams or missing audio packets can interrupt recognition.
