Overview
The free online subtitle translator lets you upload an SRT, VTT, or ASS subtitle file and translate it into 15+ languages while preserving all timecodes. Supports Chinese, English, Japanese, Korean, Spanish, French, German, and more. The AI considers context across lines rather than translating word-by-word, producing natural, fluent subtitles ready to use.Pain Point
Launching a video internationally or producing bilingual study subtitles usually means either hand-translating line by line, or using auto-translators that break context and corrupt timing. This tool delivers a one-click translation while keeping every timestamp intact — saving hours from localization to release.Key Features

- AI translation into 15+ languages: zh / en / ja / ko / es / fr / de / pt / ru / ar / hi / th / vi / id / tr
- Preserves all timecodes and formatting
- Context-aware translation — not literal word-for-word
- Free to use, no sign-up required
Highlights
Upload, pick a target language, download the translated file — three steps, timestamps untouched. The AI reads surrounding lines for context, producing more natural output for dialogues, technical terms, and slang compared to basic translators. Ideal for batch-translating long videos.Use Cases

Tips
- Use BibiGPT’s subtitle downloader to extract subtitles from videos first, then translate with this tool
