Speed Player
Speed Player is a Safari extension for Mac that lets you change video playback speed on websites and set default speed behavior.
What is Speed Player?
Speed Player is a Mac-compatible Safari extension for adjusting playback speed on web video. It is designed for people who watch lectures, tutorials, recorded meetings, and other browser-based video and want faster or slower playback without relying on each website’s built-in controls. Users can change speed while watching, set a default playback rate, and apply that default broadly or only to longer videos. The app also supports keyboard shortcuts for quick speed adjustments during playback. On Mac, it fits into a Safari-based workflow rather than acting as a standalone desktop media player.
Key features
- Change playback speed for videos on websites in Safari.
- Set a default playback speed for everyday viewing.
- Apply default speed settings to all videos or only longer videos.
- Use keyboard shortcuts to increase or decrease playback rate quickly.

Safety overview
Status: Mostly safe
Speed Player uses Safari extension access to read and modify webpages so it can change video playback speed, which is consistent with its purpose. The app store listing says it does not collect data from websites you visit. As with any browser extension, review Safari’s extension permissions and keep only extensions you actively use.
Recommendation: Keep Speed Player if you regularly adjust web video speed in Safari on your Mac. If you no longer use Safari playback controls from this extension, you can remove it without affecting unrelated apps, though its website video speed features will stop working.
