A free, browser-based batch subtitle translation tool for .srt, .ass, .vtt, and .lrc files that strips timing locally and sends only dialogue to translation engines, preserving timelines. It supports 120+ languages via 8 traditional translation APIs and 27 LLM providers, with a CLI for headless scripting.

Use cases

• translate a whole season of srt subtitles in one batch
• create bilingual subtitles for youtube or language learning
• convert srt to vtt or ass while translating
• translate subtitles without breaking timecodes
• batch translate vtt files into multiple languages at once
• translate lrc lyrics files with ai
• keep subtitle translation private in the browser

When to choose

• you need to translate many subtitle files at once without touching timing
• you want bilingual subtitle output with preserved alignment
• you prefer a privacy-focused tool that runs entirely in the browser
• you need support for many subtitle formats and multiple target languages in one pass

When to avoid

• you need to translate video audio directly rather than existing subtitle files
• you require server-side or API-based subtitle translation pipelines
• you need subtitle editing features beyond translation, like syncing or styling
