Bilingual subtitles: merge two SRT files into one

Have your subtitles in two languages, for example Arabic and English? Merge them into one file that shows both, one line under the other. Useful in the Gulf, where one video speaks to Arabs and expats at the same time.

Runs fully in your browser: your file never leaves your device.

How it works

1

Add the top subtitles

The language that should show first, for example Arabic.

2

Add the second file

The language that goes underneath, for example English.

3

Download one file

Every subtitle now has both lines, matched by time.

How the two files are matched

Each subtitle in the top file gets the line from the second file that overlaps it most in time. So the files don't need the same number of lines, only roughly the same timing. Arabic lines get right-to-left marks so players show them correctly.

When two languages help

In the UAE, Saudi Arabia and Qatar a large share of the audience doesn't read Arabic, and many Arabs prefer it. A post with both languages reaches both groups without making two videos. It also helps learners and international customers.

Two languages burned into the video

Raw2Reel can do this on the video itself: the spoken captions word by word, with a smaller line in a second language underneath, in one click. The first 3 videos every month are free. Other editors that put captions on the video are compared in the best AI video editors for Reels.

Questions

How do I make subtitles in two languages?

Merge two subtitle files in the tool above: one in each language. The result shows both lines at the same time.

Do both files need the same number of lines?

No. Lines are matched by time, so small differences in how the text is split are fine.

Which language goes on top?

The one you add first. Put the language most of your viewers speak on top.

Does YouTube show two-line subtitles?

Yes. Upload the merged SRT as one subtitle track and both lines show.

Can I get both languages on the video itself?

Yes, with Raw2Reel: turn on a second caption line in another language and it is burned into the video.
