Overview
People search for ways to add subtitles to MP4 when a finished video needs captions for YouTube, courses, or social clips. You do not need Premiere for a first pass. Upload the MP4, get a timed transcript, fix names in the editor, then export SRT or VTT.
This page runs File Transcribe's upload-to-captions workflow on your MP4. Proofread the draft in the browser. Guests can try without signup. Free accounts export SRT and VTT.
Why generate captions from the MP4 itself?
Burn-in tools assume you already have a caption file. Most creators still need the speech-to-text step. Starting from the MP4 keeps timing aligned with the audio and avoids retyping hooks by hand.

Frequently asked questions
How do I add subtitles to an MP4 online?
Upload the MP4 on this page, wait for the timed transcript, edit if needed, then sign in free to export SRT or VTT.
Can I burn subtitles into the video file here?
This page creates soft subtitle files (SRT/VTT) you attach in YouTube Studio or your editor. Burn-in into the MP4 pixels is a separate ffmpeg job and is not this tool.
Is adding subtitles to MP4 free?
Yes to try within guest limits. Free accounts get SRT and VTT export.
Does this work for Zoom or Meet recordings?
Yes. Download the meeting MP4, upload it here, and export captions. See /transcribe/zoom-meetings for that workflow.
What if I only have audio?
Use Audio to text or Subtitle generator with an MP3 or M4A. Same caption export path after signup.
Need unlimited transcription?
Upload on the homepage for free, edit in the browser, export TXT or sign in for subtitles.
