Online AI Subtitle Translator

SubtitleFlow translates both SRT and VTT subtitle files. Upload either, choose a target language, and export the same format back with the timing intact.

Because each line is translated in the context of the surrounding dialogue rather than word by word, translations read naturally. You can review and edit every line before exporting, so you stay in control of the final wording.

The opening lines translate free with no account so you can check quality first; longer files are covered by a paid plan.

Upload the movie's SRT or VTT subtitle file, choose a target language, and the AI translates every line in context while keeping the timing locked to the film. Review line by line, then export a publish-ready subtitle file — or keep the original language alongside it for bilingual subtitles. The opening lines are free to try without an account.

Yes — the first lines of any SRT or VTT subtitle file translate free with no account so you can check the quality before committing. Longer files are covered by a paid plan, and the subtitle timing never shifts.

A subtitle-aware translator works on the file itself: it translates each cue in the context of the surrounding dialogue rather than word by word, preserves the SRT/VTT numbering and timestamps, and exports a ready-to-use file — instead of returning loose text you'd have to re-sync by hand.

Yes. The timecodes are treated as fixed — only the dialogue text is translated and placed back into the original cues, so nothing drifts or needs re-syncing. Each line also stays inside its own cue, so text never bleeds into the next subtitle, even on a long film.

Yes — it's built for full-length films, documentaries, and series. The whole script is used as context so character names and recurring terms stay consistent across every episode, and the timing stays locked from the first line to the last.
