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.

SRT Subtitle Generator turns a plain voiceover script into a standard .srt subtitle file, splitting your text by punctuation, character count or total video duration.

How to Use

Step-by-step instructions

2. Choose a split mode: by punctuation, by character count, or evenly across the total duration.
3. Set the characters per line, the total video length and the start offset to match your footage.
4. Adjust the gap between lines if you want the captions to breathe.
5. Check the generated cue list and the timestamps in the preview.
6. Download the .srt file, or copy the raw text into your editor.

How it works

Step-by-step instructions

1. Paste the script. Drop in the narration text. Punctuation helps the separator produce sensible sentence boundaries.
2. Pick a split mode. Punctuation mode follows sentences; character mode keeps lines short; duration mode spreads cues evenly over the video length.
3. Set the timing. Enter the total video duration, the start offset and the gap you want between cues.
4. Review the cues. Check the generated list for awkward breaks and adjust the character limit or mode if needed.
5. Export. Download the .srt file or copy the raw caption text into your editor.
