Subtitle Splitter

Split a subtitle file into smaller SRT parts by time or cue count. Useful when a video is divided into multiple files or a long subtitle needs smaller chunks.

Upload subtitle file
Upload SRT, VTT, ASS, or SSA. Output parts are downloaded as SRT.

Split mode

Use seconds, MM:SS, or HH:MM:SS. Cues are assigned by their start time.

Output: 0 partsDownload each SRT part below.
Split results
Review each generated part before downloading.
Upload a subtitle file and choose split settings to generate SRT parts.

Split long subtitles into clean SRT parts

Use the subtitle splitter when a video has been divided into multiple clips or when a large caption file needs smaller pieces for review, editing, or platform upload.

Split by time

Cut a subtitle file at a specific timestamp such as 00:30:00 or 1800 seconds.

Split by cue count

Break a long subtitle file into smaller parts with a fixed number of cues.

Reset part timing

Rebase exported parts so each segment can start near 00:00 when used with split videos.

Download SRT parts

Review generated parts and download each one as a standard .srt file.

Subtitle split examples, timing reset, and export notes

Use a subtitle splitter when one long subtitle file needs to become smaller SRT parts. You can split at a timestamp for video segments or split by cue count for review batches.

Example input and output

Original file
1 00:00:05,000 --> 00:00:07,000 Part one line. 248 00:30:04,000 --> 00:30:08,000 Part two line.
Part 2 with reset timing
1 00:00:04,000 --> 00:00:08,000 Part two line.

Best for

Split video parts

Cut subtitles at the same timestamp where a long video was divided into multiple clips.

Smaller review files

Break a large subtitle file into manageable cue-count chunks for editing or proofreading.

Platform limits

Create smaller SRT files when an upload workflow or editor handles shorter subtitles more reliably.

Common file issues handled

Split by start time

When splitting by time, cues are assigned to a part based on their start timestamp.

Timing reset

Reset timing for each part when the exported subtitle should match a separate video segment.

SRT output

Inputs can be SRT, VTT, ASS, or SSA, and each exported part is a clean SRT file.

Manual edge cases

If a cue crosses the split boundary, review it in the subtitle editor after splitting.

Frequently Asked Questions

Can I split an SRT file into two parts?
Yes. Upload the subtitle file, choose split by time, enter the cut point, and download the generated SRT parts.
Can I split by number of subtitle cues?
Yes. Choose split by cue count and enter how many cues should be included in each exported part.
Should I reset timing for each part?
Reset timing when each subtitle part will be used with a separate video segment. Keep original timing when the parts still refer to the original full video timeline.
Does the splitter upload my subtitle file?
No. Splitting happens locally in your browser after the page loads.
