Extract Subtitles from Video

Yes. Captions are generated with precise start/end times from the spoken audio, and you can fine-tune any line in the editor before exporting — so the final SRT/VTT stays perfectly in sync.

Export standard SRT or VTT files that work with YouTube, TikTok, Instagram, Bilibili, Premiere Pro, DaVinci Resolve, and most online players and editors.

Yes. Generate captions in the original language, then translate them into 50 languages with context-aware AI while keeping the timing intact.

Yes. Videos are processed over an encrypted connection, stored privately to your account, never shared or made public, and removed under our data-retention policy.

Upload your MP4, MOV, or WebM to SubtitleFlow — the audio is extracted in your browser, then AI generates timed captions from the speech. Review and edit each line, then export an SRT or VTT subtitle file. Starting is free and needs no account.

Generate captions from your video with SubtitleFlow, fine-tune them in the editor, and export an SRT file (for YouTube) or VTT. Upload that file alongside your video, or burn the captions in with your editor. You can also translate the captions into 50 languages for an international audience.

SubtitleFlow auto-generates captions straight from a video's audio with accurate timing, supports 50 languages, and lets you review every line before exporting SRT or VTT — so you get platform-ready captions without manual transcription or hand-syncing.

Upload the video to SubtitleFlow. It extracts the audio in your browser, transcribes the speech into timed lines, and lets you review them and export an SRT or VTT file. No account is needed to start.

Yes. Upload the MKV like any other video and SubtitleFlow generates a timed SRT from its speech. If the MKV already contains a subtitle track and you only need that exact track, a track tool such as MKVToolNix can copy it out without transcription.

No. SubtitleFlow does not read text from the video frames; it creates subtitles from the spoken audio. That usually gives a cleaner, fully editable file — and it works even when the burned-in subtitles are in a language you don't need.

Yes. After the subtitles are generated in the original language, translate them into any of 50 languages with the timing kept, then export SRT or VTT.
