Convert MP4 to text

An MP4 is almost always a video file with a soundtrack you actually want: a recorded meeting, a course video, a phone recording exported as MP4. Hushscript pulls just the audio out in your browser, transcribes it with every speaker labeled, and hands back a document or a set of subtitles, ready to drop into an editor if that’s the next step. The video itself never has to leave your device, and neither does the audio once your transcript is done.

The video never uploads: here’s how

The moment you drop an MP4, your browser starts extracting the audio track itself, with no server involved yet. It runs the same way the free extract-audio tool does: entirely on your device, using your device’s own processing power, not ours. Only the resulting audio file, usually a fraction of the video’s size, gets sent for transcription. Once your transcript is ready, that audio is deleted too, and the transcript itself is encrypted at rest, so even a leak of our storage would expose only unreadable ciphertext, never your words.

Convert an MP4 to text in three steps

Drop your MP4, let the browser extract the audio, and preview the first 30 seconds free, with no account needed yet. Sign up to transcribe the rest: your first 30 minutes are free, instant when you validate a card (a $1 hold, released right away, never charged), or with your first purchase if you pay another way. If the recording is split across several MP4 files (a multi-part meeting, say), merge them into one ordered transcript before you start.

Speaker-labeled, with subtitles

Every transcript separates each speaker automatically and for free, so a two-person interview or a five-person meeting reads as the conversation it was, not one block of text. From there, export subtitles in the same job: SRT and VTT for most players, ASS for styled captions, TTML for broadcast platforms, SBV for older players, and LRC for lyric-sync, plus FCPXML and EDL timeline markers for Final Cut, Premiere, and Resolve. None of it is a paid add-on; it’s the same export set every transcript includes. Rename “Speaker 1” to a real name and every exported caption file updates to match.

Extract just the audio, free

Don’t need a transcript at all, just the audio out of the MP4? The free extract audio from video tool does that on its own: drop the file, keep the original audio untouched or convert it to MP3, WAV, FLAC, and other formats, and download it, all in your browser with nothing uploaded. It’s useful beyond transcription too: pulling a clean audio track to share separately, archive on its own, or drop into an editing project that only needs the sound. Change your mind afterward? Transcribe the same file any time; your first 30 minutes are free.

MOV, WebM, and other video formats

Got a different container? MOV, WebM, MKV, and more all work the same way: audio extracted in your browser, nothing uploaded, whatever the source device or app happened to produce. Or convert it to MP4 free first if that’s what you actually need for something else, like sharing the file with someone whose player only opens MP4.

Free, no subscription

Hushscript itself isn’t free: transcription runs on top-tier AI, so it’s pay-as-you-go with no subscription. New accounts get 30 free minutes after a quick payment-method check. A card’s $1 hold is released immediately, never charged. Then pay as you go. Packs run from $1.99 for 45 minutes to $49.99 for 100 h (6,000 min); the full table is on pricing. For a genuinely free tool with nothing to buy, extract audio from video never asks for an account.
