Translate a subtitle file
Your file is processed on your device. Nothing is uploaded, and there is no size limit.
TL;DR
Drop an .srt or .vtt file, pick a target language, press Translate and download. It is free and unlimited, and translation runs in your browser's built-in on-device model, so nothing is uploaded. Limit: desktop Google Chrome 138+ or Microsoft Edge only, and each new language pair downloads once.
