Frequently Asked Questions
- Why doesn't fullscreen work?
- Some browsers require a direct user interaction (like a click) to enter fullscreen. Embedded iframes may also block fullscreen. Try using this tool directly rather than through a frame.
- Is fullscreen the same as F11?
- Not exactly. F11 is a browser-level fullscreen that hides the browser UI. The Fullscreen API is a web standard that allows websites to request fullscreen. Both achieve a similar result but work differently.
