How to batch translate subtitles

  1. 1

    Upload subtitle files

    Add multiple SRT, VTT, ASS, or SSA files to the batch queue. The tool counts visible subtitle characters before translation.

  2. 2

    Choose target languages

    Select one or more output languages. Each file-language pair becomes a separate AI translation task using the normal credit rules.

  3. 3

    Download the ZIP

    When all translations finish, download one ZIP archive with translated subtitle files grouped by language.

Batch subtitle translation examples, credit planning, and ZIP export

Batch subtitle translation is useful when the same set of timed subtitle files needs to be localized into several languages. Upload multiple files, choose target languages, and download completed translations as one archive.

Batch input
episode-01.srt + episode-02.srt + trailer.vtt
ZIP output
es/episode-01.es.srt es/episode-02.es.srt fr/episode-01.fr.srt
