Subtitle Translator is a browser-based translation utility designed to process large collections of subtitle files while preserving their original timing. It supports SRT, ASS, VTT, and LRC formats with translation into more than 120 languages. Users can upload hundreds of files and translate an entire television season in one operation. Its processing engine separates dialogue from timestamps, preventing translation models from altering synchronization. The application connects to eight traditional translation APIs and 27 AI model providers and gateways. Context-aware translation improves dialogue consistency, while bilingual output retains original text alongside translations. It also supports subtitle format conversion, multilingual exports, and persistent browser caching. A command-line interface enables automated translation workflows.
