(An HTML file that can be opened and used in the browser without an internet connection)
This packages your Scratch project into a single HTML file that can run on its own in a web browser. The HTML file will be pretty big because it contains the entire Scratch engine (2.6 MB) and the costume and sound files used in the project. There is no direct translation between a Scratch block and a JavaScript equivalent because the two languages are fundamentally different, so you should not use the code in the generated file for learning HTML or JavaScript after Scratch.
The project will automatically start, and there are no green flag or stop sign buttons.
1You may have to deal with privacy laws around cookies outside of Scratch.
2Compatibility mode forces projects to run at 30 FPS, like in Scratch 2.0. Turning this off allows the project to run at a higher framerate (usually 60 FPS, depending on the computer screen's refresh rate).
