What is a YouTube subtitle generator?
A YouTube subtitle generator creates timed captions for uploads. Start in 16:9, tidy the lines, then either put captions on the video or download SRT for YouTube Studio — and remix to Shorts when needed.

16:9
Subtitles framed for classic YouTube uploads
This page opens the studio at 16:9 so talking-head and screen videos get caption placement that matches horizontal players.
Studio upload
On-video captions — or SRT for YouTube Studio
Some videos want captions on the picture; others need a clean .srt. Generate once, then choose the path that matches the upload.
Shorts
Cutting a Short from the same captions?
Switch aspect to 9:16 in the studio when you remix a horizontal video into a Short — caption styles travel with you.
Ship
Export for Watch or Studio
Download a captioned MP4 for silent-friendly playback, or pull SRT for YouTube Studio — same captions either way.
