Subtitle Edit
Subtitle Edit is a desktop subtitle editor for macOS that helps you create, edit, sync, translate, and convert subtitle files for video.
What is Subtitle Edit?
Subtitle Edit is a subtitle editing app for macOS built for people who create, correct, time, and convert subtitles for video. It is useful for translators, caption editors, video producers, and anyone preparing subtitle files for playback, distribution, or post-production work. The app supports a wide range of subtitle formats and includes tools for adjusting timing, synchronizing lines, previewing subtitles with video, and fixing common subtitle errors. It also offers features for format conversion, batch work, OCR-related subtitle tasks, and optional speech-to-text or translation workflows through supported services. Subtitle Edit is a native desktop workflow rather than a web app, so users can work locally with their subtitle and media files. Published by Nikse, it is commonly used for subtitle preparation, cleanup, and conversion across different video and localization workflows.

Safety overview
Status: Mostly safe
Subtitle Edit is legitimate subtitle-editing software. It normally needs access to the subtitle and media files you open, and some optional features may send selected content to third-party online services for translation, speech recognition, OCR, or similar tasks. That kind of access is consistent with what the app does, but you should avoid using online features with sensitive media unless you are comfortable with the provider involved. Removing the app will stop its subtitle editing and conversion features, but it should not affect macOS itself.
Recommendation: Keep Subtitle Edit if you use your Mac for subtitle creation, correction, timing, or format conversion. If you installed it only for a one-time project and no longer need those workflows, you can remove it without affecting the rest of your system.
