Subtitle Edit

Subtitle Edit is an offline desktop application for people creating captions or revising subtitle files alongside video. Editing, format conversion and playback run on your computer. Optional translation and speech services send requests to external providers.

You can revise subtitle files, convert them between formats and watch the accompanying media while working. Automatic backups stay on your device. These core functions don't need an internet connection.

Online services cover translation, speech-to-text, text-to-speech, OCR and dictionary lookups. When you use one, the application sends only the data needed for that request directly to the selected provider, whose privacy policy applies. Subtitle Edit doesn't retain or forward that request data, or collect subtitle content, media content or associated metadata for analytics or model training.

The application is open source under the MIT license and runs on Windows, macOS and Linux. It requires fully updated Windows 10 22H2 or newer, or macOS 12 or newer. macOS 14 or newer is recommended because the runtime isn't tested against macOS 12 and 13.

The macOS app and Linux Flatpak include the media components for playback. Native Linux builds use mpv and ffmpeg for video functionality.
