You can select multiple files at once. All files must use the same format.
Tips:
Merge order matters. Arrange files by timeline, episode, or segment order. Only files with the same format can be merged.
When do you need to merge subtitles?
Use this tool when a video is split into several parts, a course is exported by chapter, episode subtitles need to be combined, or two matching subtitle tracks need to become a bilingual SRT/VTT file.
Which merge mode should you choose?
Direct merge works when timestamps are already continuous. Sequential merge shifts later files automatically. Bilingual merge is for two files with the same timing but different languages.
Subtitle merge FAQ
How does sequential merge handle timestamps?
Each file is normalized to its own first subtitle, then placed after the previous file. This is useful when subtitles were exported from separate video segments.
When should I use bilingual merge?
Use bilingual merge when two subtitle files have the same number of blocks and matching timelines but different languages. The tool uses the first file timeline and places both languages in each block.
