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 workflows, and subtitle review.

Review names, terminology, punctuation, line breaks, and unclear phrases before the SRT or VTT file reaches your publishing workflow.

Use this page when you need caption files beside the MP4, rather than text rendered permanently into the video image.
