How to convert video to text online
Upload a file, let the browser extract and compress audio with FFmpeg WebAssembly, then transcribe and download TXT, SRT, or VTT.
Upload or drop your video
Select an MP4, MOV, WebM, MKV, AVI, or M4V file and start. The browser keeps raw frames local and processes audio with WebAssembly.
Automatic language detection or choose one
Let the tool detect the spoken language, or select it to improve accuracy for interviews, lectures, and multilingual recordings.
Review, edit, export
Edit the readable transcript in the browser, then export as TXT, SubRip SRT, or WebVTT VTT with cue timings ready for YouTube or e-learning.
Video transcription features
Local video processing
FFmpeg WebAssembly extracts and compresses the audio track inside the browser, so raw video frames are never uploaded.
AI speech recognition
OpenAI Whisper converts spoken dialogue into readable text and provides word level timestamps for accurate cue placement.
Timed subtitle export
Download the result as plain TXT, SubRip SRT, or WebVTT VTT with usable cue timings for YouTube and course platforms.
Long video support
Long recordings are split into ten minute audio chunks, transcribed, and recombined into a single ordered transcript.
Language selection
Automatically detect spoken language or pick one from the supported menu to improve transcription for interviews and lectures.
Editable preview
Review and edit TXT, SRT, or VTT output in the browser before downloading, so captions and quotes are production-ready.
Automatic subtitles benefits
Video frames stay private
Only the compressed audio track leaves the device; raw video frames are never uploaded for transcription or storage.
Caption video faster
Generate a timed subtitle draft automatically, saving hours compared to manual captioning and timestamping.
Search video content
Turn spoken video into searchable text you can quote, index, summarize, and repurpose for articles or show notes.

Reuse a single recording to create captions, notes, lesson transcripts, and accessibility text for multiple platforms.
Video to subtitles for creators

Speech to text from video questions
How to convert video to text online with SubTran?
Upload your file, allow the browser to extract and compress audio with FFmpeg WebAssembly, then start transcription. Review the editable transcript and download TXT, SRT, or VTT.
Does SubTran keep video frames local?
Yes. The browser extracts and compresses the audio track locally, so only compressed audio is sent for AI transcription, not raw video frames.
How accurate is AI transcription for interviews and lectures?
Accuracy depends on audio quality, speaker clarity, and background noise. Using a clear recording and selecting the correct language improves results for interviews and lectures.
How to transcribe MP4, MOV, WebM, MKV, AVI or M4V?
Select one of those common formats in the uploader. The browser handles extraction with FFmpeg WebAssembly, then the audio is transcribed by OpenAI Whisper.
How to create timed subtitles SRT or VTT from video?
Transcribe the video, open the SRT or VTT view, edit cue text if needed, and download the subtitle file with aligned timestamps for YouTube or e learning.
Is browser based transcription with WebAssembly secure?
Browser based extraction using WebAssembly keeps raw frames local and reduces upload size. Only compressed audio is transmitted for transcription, which limits exposure of visual content.
How to export subtitles for YouTube or e learning courses?
After editing, export as SubRip SRT or WebVTT VTT. Both formats are accepted by YouTube and most e learning platforms for timed captions.
Can teams collaborate on video transcripts with SubTran?
SubTran provides an editable browser preview you can copy and share. For multi user workflows, export TXT, SRT, or VTT and import into your team tools or CMS.
