Keeps your timing
Only the text is translated — every timestamp stays exactly as it was, so the subtitles still sync perfectly.
15+ languages
Translate captions into Spanish, French, German, Hindi, Arabic, Japanese and many more.
Standard SRT & VTT
Export files that work with YouTube, social platforms and every major video editor.
Localize a YouTube SRT into Spanish
Export your video's English captions as an SRT, drop the file here, and pick Spanish to get a translated subtitle track with every timestamp left untouched. The AI keeps each line short enough to read on screen, so the cues still sync to your speech. Download the finished .srt and upload it straight to YouTube Studio as a second caption language.
Translate VTT captions for a course player
HTML5 video players and LMS platforms expect WebVTT, so upload your .vtt lesson captions and translate them into German, French, or any of the 15+ supported languages. The original cue timings stay byte-for-byte aligned, and you export a fresh .vtt file ready to drop back into your <track> tag or course host without re-syncing a single line.
Make foreign-language subtitles readable
Got an SRT in a language you don't speak from a film, interview, or anime release? Upload it and translate every cue into English while the timecodes stay locked to the footage. The translator is tuned for concise on-screen wording rather than wordy paragraphs, so the result loads cleanly in VLC, Plex, or any player that reads SRT files.
