An automatic subtitle generator turns the speech in your video into accurate, perfectly-timed captions without you typing a single word. Upload a clip, the audio is transcribed, and the text is burned straight into the frame in the same bold, viral-clip style creators use on Shorts, Reels, and TikTok — no signup, no watermark, no cost.
Most people search for a subtitle generator because manual captioning is slow and error-prone. Lining up text to audio by hand takes longer than recording the video itself. This free tool removes that work entirely: the transcription, the timing, and the on-screen styling all happen automatically, and you get a finished captioned video back in the same session.
Captions are not optional anymore. The vast majority of social video is watched on mute, and clips with burned-in subtitles hold attention far longer than bare footage. Adding automatic subtitles is the single highest-leverage edit you can make to a short before you post it.
How to generate subtitles automatically
- 1. Upload your video
Drop in an MP4 or MOV — a talking-head clip, podcast cut, interview, or screen recording. Everything runs in your browser; the file is not sent anywhere to be stored.
- 2. Auto-transcribe the speech
The tool detects spoken words and converts them into time-coded caption lines automatically, so each phrase appears exactly when it is said.
- 3. Pick caption position and style
Choose top, center, or bottom placement and the viral caption look. The styling is baked in — no separate font, color, or animation setup needed.
- 4. Export the captioned video
Get your video back with subtitles burned into the frame, ready to upload straight to TikTok, Reels, or Shorts. Free, no signup, no watermark.

Automatic subtitle generator FAQ
Is this subtitle generator really free?
Yes. You can upload a video, generate automatic subtitles, and export the captioned result for free, with no signup and no watermark on the output.
Do I have to type or sync the captions myself?
No. The speech is transcribed automatically and each line is time-coded to the audio, so you never type or hand-sync anything. You only choose where the captions sit and the style.
What video formats can I upload?
Standard formats like MP4 and MOV work well. Talking-head clips, podcast cuts, interviews, and screen recordings are all good candidates.
Are the subtitles burned into the video?
Yes. The captions are rendered directly into the frame so they display everywhere you post — TikTok, Instagram Reels, YouTube Shorts — with no extra subtitle file required.
Will it add subtitles automatically or do I need a transcript?
It is fully automatic. You do not need to provide a transcript or an SRT file — the tool generates the subtitle text from the audio for you.
Can I control where the captions appear?
Yes. Pick top, center, or bottom placement so the captions never cover faces or important on-screen action.
