How to split subtitle files
Use Subtitle Splitter to divide one local SRT or WebVTT file into parts. Choose a time range, cue range, maximum cue count, file-size target, or chapter markers, review the segment boundaries, select the timestamp style, and download the parts as one ZIP.
Choose how to split an SRT or WebVTT file
The Subtitle Splitter starts with one subtitle file and applies the rule you select:
- Time range: divide at the time boundaries you provide.
- Cue range: split by subtitle cue positions.
- Maximum cue count: set the highest cue count for each part.
- File-size target: split with a target size for each part.
- Chapter markers: use chapter markers you supply as the segment boundaries.
Set absolute or relative subtitle timestamps
After setting the boundaries, choose absolute or relative output timestamps. Absolute timestamps keep each cue on the source timeline. Relative timestamps shift each part to its own timeline for use as a separate subtitle file.
Input: one SRT file with chapter markers
Output: several subtitle parts, packaged in one ZIPReview the boundary preview before downloading. Check chapter markers and cue boundaries that sit close to a subtitle change.
What Subtitle Splitter does with your file
Subtitle Splitter works with a local SRT or WebVTT file in your browser. The file is not uploaded. Provide the markers, ranges, count, or target for the split, then download the resulting parts in a ZIP.
Use a time range for known start and end points. Use a cue range for a selected block of captions. Maximum cue count and file-size target rules set boundaries using the values you provide.
Where splitting subtitle files comes up
- An editor has one long SRT for a recording and needs separate subtitle files for its chapter markers.
- A caption reviewer needs one cue range as its own subtitle file.
- A production workflow needs subtitle parts organized around a maximum cue count or a file-size target before the files are downloaded.
- A WebVTT file needs to be divided at chapter markers.
When to use Subtitle Splitter
Use Subtitle Splitter when one SRT or WebVTT file needs several files with boundaries you choose. Go to Subtitle Tools for converting, retiming, styling, merging, or validating subtitles.
