Subtitle Split Tool
Divide a subtitle file into several files. Split at a time – for a film cut into two video files – into a number of equal parts, or every so many cues. Each part can be shifted to start at 0:00, so it matches the corresponding video file, and all parts download as separate .srt or .vtt files or one ZIP.

Subtitle Split Tool FAQ
How do I split for a film in two parts?
Choose “At a time”, enter the exact length of the first video file (for example 01:02:30) and keep “Start each part at 0:00” on.
What happens to a cue that crosses the split time?
Cues are assigned to a part by their start time, so a cue starting before the split stays in the first part.
How are equal parts calculated?
By duration: the time from 0:00 to the last cue is divided evenly, and each cue goes to the part in which it starts.
Can I join the parts again?
Yes, with the Subtitle Merge Tool in append mode.
Which formats are supported?
SRT and WebVTT (.vtt), detected automatically. Open a file or paste the text.
Is my file uploaded?
No. Everything happens in your browser.
Splitting subtitles correctly
Subtitle files usually cover one video file. When a film is distributed in two parts, when a long recording is cut into episodes or when a large file must be shared among translators, the subtitles must be split the same way.
Splitting at a time is the most common case. All cues starting before the split time form the first part, the rest the second. For split videos, the second part must also be re-timed: its first frame is 0:00 again, so every cue is moved back by the split time. With “Start each part at 0:00” on, this happens automatically.
Equal parts divide the running time evenly, which is handy for distributing work. Splitting every N cues gives files with the same amount of text regardless of timing, useful for translation batches.
The overview lists each part with its number of cues and its time range, so you can check the result before downloading. Parts are named with -part1, -part2 and so on.
