Free subtitle generator: auto subtitles for any video
Kool Captions generates subtitles for your video automatically and for free. Get a plain .srt file for YouTube or your editor, or subtitles burned into a 9:16 video for Reels and Shorts, timed to every word. The SRT generator needs no account; the full editor gives you 10 minutes of transcription free.
Two ways to get subtitles
An .srt file
The free SRT generator turns a short clip into a subtitle file with no sign-up. Upload it to YouTube Studio or drop it into Premiere, CapCut or DaVinci Resolve.
Subtitles burned into the video
The editor styles the subtitles (100+ looks), lets you fix any word, and exports a finished video at 720p free, or 1080p and 4K with a package.
How it works
- Upload your video and pick its language.
- Check the words. Each one is timed to your voice; fix anything in a tap.
- Download the .srt, the captioned video, or both.
