Combine multiple .srt subtitle files into a single timeline. Works for split parts, multi-language tracks, and merged episode cuts. Clean output, no forced watermark.

Most video projects don't ship with a single tidy subtitle file. You often end up with:
Manually stitching these together — copying cue text, renumbering IDs, recalculating timestamps against a unified timeline — is exactly the kind of fiddly job that breaks. SRTKit handles the merge so you don't have to.
Drop two or more .srt files into the merge tool. You can reorder them by dragging — the order you pick is the order cues appear in the merged output.
Choose Sequential (cues stacked in time order across files) or Append (file 2's cues shifted to follow file 1's last timestamp). Sequential is the default for split parts.
If your second file's timestamps start at 00:00:00 but should actually begin at 00:45:00 (e.g. episode 2 starting at the 45-min mark of a merged cut), set a manual offset in seconds.
One click produces a single .srt with re-numbered cue IDs and a continuous, gap-checked timeline. Output is clean — no forced watermark, no extra header lines.
Can I merge SRT files with different languages into one document?
Yes. SRTKit preserves all text content from each source file and re-numbers the cues sequentially. If you want a single bilingual .srt, that's a separate workflow — this tool merges files as separate cue blocks in the order you specify. For language-specific playback, point your player at the merged file and select the language track as usual.
Will the merged file keep the original timestamps or recalculate them?
Both options are available. Sequential mode recalculates timestamps so cues appear in true time order across all files — useful when files overlap or are out of order. Append mode keeps each file's original timestamps and shifts later files by a cumulative offset you specify — useful when each file already starts at 00:00:00 and represents a separate segment.
Is there a limit on how many SRT files I can merge?
[TODO:实测] Practical limits depend on browser memory and total cue count. For most projects — merging a handful of episode files or language tracks — there are no constraints worth worrying about. Very large merges (dozens of files or millions of cues) may hit browser tab limits.
Will my merged SRT have a watermark or branding added?
No. The output is a clean .srt file with no forced watermark, no injected header lines, and no tool attribution. What you upload is what's reflected in the merged output, minus the structural cleanup.
Do I need to sign up or create an account?
No account is required to merge SRT files. Open the tool, drop your files, download the merged result. For batch merges or scripted workflows, see the batch converter or the SRT API.
For bulk merges across many projects, use the batch converter or the API.
