MP4 to Captions Converter turns spoken video content into caption-ready SRT or VTT files. Upload your MP4 now and export captions for free, no signup needed.
Upload audio or video file, then click Transcribe.
Turn MP4 courses, interviews, webinars, social clips, demos, and screen recordings into caption text aligned to the video timeline.

Download caption-ready files for YouTube, video editors, web players, learning platforms, accessibility review, and subtitle cleanup.

Review names, terminology, punctuation, line breaks, and unclear phrases before uploading captions to YouTube, editors, web players, or learning platforms.

Keep captions as separate SRT or VTT files so you can update, translate, or upload them without re-rendering the MP4.
