Subtitle Edit is a subtitle editor that runs on Windows, macOS, and Linux with cross-platform builds available.
The tool addresses the need to create, edit, and convert subtitle files with support for video playback during editing. It operates as a desktop application that processes subtitles locally on your machine, offering features like automated backup, video synchronization, and conversion between subtitle formats. The editor integrates optional third-party services for translation, speech-to-text, text-to-speech, OCR, and dictionary lookups, but these are opt-in and only transmit minimal data directly to the chosen provider.
Subtitle Edit suits anyone working with video subtitles who wants a straightforward, offline-first editor. The tool is particularly valuable for users prioritizing privacy, as it does not collect, store, or transmit subtitle or media file content. On Windows, it requires Windows 10 version 22H2 or newer. macOS users need version 12 or newer, with the application self-contained and notarized for standard installation. Linux users can install via Flatpak with bundled dependencies or through native packages if mpv and ffmpeg are available. The project provides builds that do not require a separate .NET installation.
Development activity shows consistent maintenance with cross-platform build infrastructure supporting Windows, macOS, and Linux releases. The project maintains detailed system requirements documentation and provides installation guidance specific to each platform. Documentation and FAQ resources are available through the project's website. The tool includes local auto-backup functionality as a core feature rather than an optional add-on.
