How splitting chooses a boundary
The splitter prefers punctuation and word boundaries so text remains readable. Long unbroken text is cut only when a configured text limit requires it.

Questions about this tool
Does splitting add more time to a subtitle?
No. It distributes the existing interval. If the text is still too dense, review the wording or timing in your editing workflow.
Do my files or text leave this device?
Your source content is processed in this browser, not uploaded for processing. The browser may download a processing engine from Voice2Sub’s CDN. Those engine requests do not contain your source file.
Need subtitles created automatically from audio or video?Voice2Sub can transcribe spoken audio when you need a complete subtitle workflow instead of a file utility.
