Frequently Asked Questions
It divides a single subtitle file into multiple smaller files. You can split by a fixed number of cues per file, by a target number of equal parts, or at a specific timestamp.
If you choose 3 parts, the file is divided as evenly as possible into 3 parts. Cue counts are balanced using ceiling division, so some parts may have one more cue than others.
Yes. Each output part has its cues renumbered sequentially starting from 1, regardless of the original numbering.
If you set 500 cues per file and your file has 1200 cues, the splitter creates 3 files: part 1 (cues 1-500), part 2 (cues 501-1000), and part 3 (cues 1001-1200). Each part is renumbered starting from 1.
The splitter finds the first cue whose start time is at or after the specified timestamp. All cues before that point go into part 1, and the rest go into part 2.
Yes. When the split produces multiple parts, you can download all of them as a single ZIP file, or download each part individually.
