Easily control the playback speed of HTML5 videos and audio across websites in Safari. This Safari extension offers quick controls, rich customization options, and convenient keyboard shortcuts.

Key Features:
• Quick Popup Controls – Adjust speed instantly with a slider, plus +/- buttons and customizable preset buttons.
• Precision Slider – Define your own minimum, maximum, and step values for fine-tuned control (0.1x–16x).
• Initial Speed Options – Choose to automatically apply the last used speed, a custom default speed, or start at normal speed.
• Keyboard Shortcuts (macOS only) – Assign custom keys to increase or decrease speed by a chosen amount, or jump directly to a specific speed. Both the speed values and key bindings are fully customizable.

Limitations:
• Works only with HTML5 media.
• Some websites may block speed control or restrict playback speeds (e.g., limit to 2x).
• Embedded videos may require opening the original source page.
• Due to the wide variety of websites, compatibility with every site cannot be guaranteed. If needed, you can contact us to check whether this extension works on a specific site before installing.

This Safari extension allows you to:

・Change the playback speed of web videos/audios up to 16x the original speed.

・Set playback speeds that include a decimal point, such as 2.125x.

・Access a wide variety of customization features.

This extension works on Safari.

The playback speeds that can be set range from 0x to 16x, including speeds with decimal points.

If the speed exceeds 2x, which is the default maximum playback speed on Safari, the smoothness of the audio in videos and audio-only clips will be maintained, but the smoothness of video images will be reduced. If you wish to enjoy the images in videos as well, speeds faster than 2x are not recommended.

How to change playback speed
1. Go to the site on Safari (e.g. YouTube) where the target video/audio is located
2. Open a popup for this extension
3. Change the playback speed to your preference by clicking the slider that appears or the one-click button that allows you to change to the set playback speed

Customizable Items
・The highest value (the highest speed of the video/audio), the lowest value (the lowest speed of the video/audio), and the step on the slider.
・Default speed for playback, eliminating the need to set the speed every time.
・Playback speed settings, allowing you to decide whether the last-used playback speed will remain set for other videos/audios.
・One-click buttons to change playback speed (multiple settings possible, up to 24 buttons)

Additional Information
・If the target video/audio is embedded from an external site, the playback speed can be changed by navigating to that external site. In addition, you cannot change the speed of non-HTML5 video/audio. (However, the video/audio on most websites is HTML5, so this extension will function on most websites.)
・Due to the large number of sites, we cannot guarantee that this extension will work on all sites. Users can inquire if this extension will work on a particular site before installing it. Please contact us with the URL of the video/audio in question and we will respond within 24 hours.
