An SRT subtitle generator is an online tool that automatically creates subtitle files from video content. It uses AI speech recognition to detect spoken words, split them into timestamped segments, and produce a standard .SRT (SubRip Text) file that works in all major video editors and platforms including CapCut, Premiere Pro, DaVinci Resolve, YouTube, TikTok, and Instagram.
Upload your video file (MP4, MOV, WebM, or MKV). Our AI extracts the audio track, processes it through advanced speech recognition powered by Whisper, and generates precisely-timed subtitle segments. The result is a downloadable .SRT file with accurate timestamps and clean text formatting. The entire process takes just seconds for short-form videos.
We support all popular video formats: MP4, MOV (iPhone/iPad video), WebM (screen recordings), and MKV. Maximum file size is 100 MB with a 5-minute duration limit, optimized for Reels, TikTok, YouTube Shorts, and other short-form content. The generated .SRT file can be downloaded or copied directly.
Our subtitle generator supports 15+ languages with automatic language detection. Whether your video is in English, Spanish, French, German, Portuguese, Italian, Russian, Ukrainian, Turkish, Japanese, Korean, Chinese, Arabic, or Hindi — the AI will accurately transcribe speech and generate subtitles in the original language.
