LanguageSubtitleTranslator

Language Subtitle Translator is an AI-powered subtitle conversion and translation workflow for making your captions accessible in multiple languages. Upload your subtitle file, choose source and target languages, and generate translations with batch support for faster localization.

The tool supports common subtitle formats including .srt, .vtt, .ass, .sub, .sbv, .lrc, .smi, and .txt. It can translate a single file into more than 100 languages, and single-file uploads can be translated into up to 5 target languages at once. Multiple files can be processed together, but output is limited to one language per batch.

After translation, you can preview results and refine them in the integrated subtitle editor. You can also convert subtitles into plain text when you want caption content for posts or other reuse.
