Split Subtitles

What this tool does

This tool cuts one subtitle file into several files: at the times you enter, every so many subtitles, or into equal parts. Each part can start again at 00:00:00 so it matches a split video. Parts keep the original format and line endings.

How to split a subtitle file

1. Select Choose files and add a subtitle file, or use Paste text.
2. Under Split, choose At times, Every N subtitles or Into equal parts.
3. Enter the time, such as 00:45:00,000, the number of subtitles per part, or the number of parts.
4. Select Split and check each part in the result.
5. Select Download all (ZIP), or Download next to one part.

Options explained

• Split at takes one or more times. Separate several with “;”, for example 00:30:00,000; 01:00:00,000.
• Subtitles per part defaults to 500. Number of parts defaults to 2, up to 20.
• Start each part at 00:00 is on. Every part then starts at zero.
• Each part keeps the input format and line endings and is saved as UTF-8, named with “.part1”, “.part2” and so on.
