FAQ

Can I translate SRT subtitles from Spanish to English for free?

Yes. The tool on this page translates .srt and .vtt files from Spanish to English for free, with no account and no watermark. It runs in your browser, so your file is never uploaded.

Will the subtitle timing stay intact?

Yes. Only the text lines are translated; every timestamp is preserved exactly as in the original file.

Is machine translation good enough for English subtitles?

For personal viewing and language learning, absolutely. For publishing, treat it as a first draft: machine output for English is strong on everyday dialogue but should be reviewed for idioms and formatting before release.
