Features

SRT Subtitle Generator is a free local tool that turns any pasted script or caption text into industry-standard .srt subtitle files directly in your browser. Choose to split lines by punctuation, character count, or evenly across a custom total duration, then fine-tune start-time offsets, per-line word counts, and millisecond timestamp formatting. Everything runs on-device — no audio, script, or timing data is ever uploaded to a server, so unreleased cuts and internal voice-over scripts stay fully private.

When You Need This

Common pain points this tool solves

1. Generating timed SRT captions for a short-video edit in CapCut, Premiere Pro, or DaVinci Resolve without importing the raw audio
2. Splitting a long voice-over script into equal-length subtitle lines for a course video or podcast clip
3. Fixing janky SRT exports from auto-transcription tools by normalizing timestamps and re-wrapping long lines to readable lengths

How to Use

Step-by-step instructions
