Free SRT Subtitle Generator

Turn a script into ready-to-use subtitles in seconds. This free SRT subtitle generator takes your caption lines, times them automatically and exports a valid .srt (SubRip) file you can drop into YouTube, CapCut, Premiere Pro, DaVinci Resolve or any video editor. Choose to spread your captions evenly across a total duration, or give every line a fixed number of seconds — the SRT updates live as you type.

Captions boost watch time, accessibility and reach, especially for short AI video clips watched on mute. Everything runs in your browser: no login, no upload, no cost.

Frequently asked questions

What is an SRT file?
SRT (SubRip) is the most widely supported subtitle format. Each entry has a number, a start and end timecode, and the caption text. It works in YouTube, CapCut, Premiere, DaVinci Resolve and almost every player.
How are the subtitle timings calculated?
In total-duration mode, your lines are spread evenly across the time you set. In per-line mode, each caption gets the same fixed number of seconds. A small gap is added between cues so captions do not overlap.
Is the SRT subtitle generator free?
Yes, completely free. It runs entirely in your browser with no account and no upload, so your script never leaves your device.
