Upload the video: we handle the audio

Drop the video file directly (MP4, MOV, MKV, WEBM…). ScribeGrab pulls the audio, transcribes it with timecodes on our GPU, and gives you a properly formatted subtitle file. No need to extract audio yourself or install anything.

How to use the subtitles
Video formats, and how the audio gets pulled out

Upload the video as-is — ScribeGrab reads MP4, MOV, MKV, WEBM, AVI, M4V, MPEG and more, up to 60 minutes and 1.5 GB. You don't extract the audio yourself, don't convert to a "supported" format, and don't install anything: the tool separates the audio track for you, transcribes it with timecodes, and builds the subtitle file. Whatever your camera, screen recorder or editor exported, drop it straight in.

How to transcribe a YouTube video

Fastest way: paste the video's link on the homepage and ScribeGrab fetches it for you. Want proper subtitles from the actual audio (usually more accurate than YouTube's own auto-captions) instead of whatever captions already exist? Upload the file directly:

  1. Get the video file. Your own upload? Download the original from YouTube Studio → Content → Download. Someone else's video? Use YouTube's own Download button where it's offered, or any downloader, for content you have the right to use.
  2. Drop the MP4 in above. No conversion, no audio extraction — ScribeGrab pulls the audio track out for you.
  3. Download your SRT, VTT and transcript. Timecoded and ready to upload straight back into YouTube's subtitle editor.

Uploading the file yourself always transcribes the real audio, so it's the more accurate route regardless of what's on YouTube already. Pasting the link is the shortcut when speed matters more than that extra accuracy.

Which videos benefit most from captions
Video quality and how accurate the captions are

The captions are only ever as good as the speech in the video. Clear narration or a single presenter close to the mic comes out very accurately. Several people talking over each other, a distant camera mic, or phone-audio compression will need a proofread pass before you publish. Background music generally isn't a problem — the model focuses on the speech and ignores most non-speech sound.

How big the files actually are

Across 3,992 measured uploads in the 40 days to 21 August 2026, the average file was 19.5 MB and the largest was 127.01 MB — nowhere near the 1.5 GB ceiling. Every single one, 100% of them, sat comfortably under the size limit; not one landed within 10% of it and not one went over. That's the opposite pattern from how long a recording runs, where plenty of people bump into the 60-minute limit: the size limit on this tool is essentially never the problem. What does trip people up here is getting the audio out of the video at all — "We couldn't get the audio for that video" was the second most common error on the whole site, hit 65 times in the same window, usually a video with no usable audio track rather than anything wrong with the upload itself.

Also just need the text? Video to text works the same way

Not every video needs captions, sometimes you just want the words as plain text: a quote for an article, a script to edit, or a transcript to search through. Upload the same MP4 (or MOV, MKV, WEBM) here and ScribeGrab hands you both (SRT/VTT subtitles and a plain TXT transcript) from that one upload. So whether the job is "video to text" or "MP4 to text", there's no separate tool to go find: the transcript comes out alongside the captions every time.

Already have the subtitle file and just need to attach it? Here's how to add it in YouTube, CapCut, Premiere, DaVinci, VLC and your own website.

Frequently asked

Is it really free?

Yes, no account, no watermark, no daily cap, no per-minute charge. Ads keep the GPU running.

SRT or VTT: which do I need?

SRT for YouTube and most editors; VTT for HTML5 web players. You get both, so use whichever fits — see our full SRT vs VTT comparison for the details.

Which video formats work?

MP4, MOV, MKV, WEBM, AVI and more, up to 2 GB and 60 minutes.

Can I just paste a YouTube link?

Yes — paste the link on the homepage and ScribeGrab fetches it for you, instantly if the video already has captions, or by transcribing the audio if it doesn't. Want the more accurate transcription regardless of existing captions? Download the video (YouTube Studio for your own uploads, or any downloader for content you're allowed to use) and upload that file instead.
