Bilingual Subtitle Merger

Q: Do both subtitle files need to be the same format?

No. You can mix an .srt and a .vtt file — each is read on its own and the merged result is always produced as a single .srt file.

Combine two subtitle files into one bilingual track, with both languages stacked in every cue. Ideal for language learners and dual-subtitle exports.

About this tool

One file, two languages, zero extra clicks

Bilingual subtitles are a common request from language learners who want to read a translation alongside the original line, and from editors preparing dual-language releases. Rather than manually copying lines between two files, this tool walks through both tracks cue by cue and stacks the matching lines together into a single new file.

Because the merge is based on cue order rather than exact timestamps, the two files you upload don't need identical timing down to the millisecond \u2014 they just need to represent the same sequence of lines, which is normally true when both were translated from the same source script.

Use the order toggle to choose whether the first file's text appears above or below the second file's text in each merged cue.

Yes. The output is a standard .srt file with two lines of text per cue, which every common media player displays correctly.
