Changing how a prototype displays in a browser

Use the View options to change how your prototype will display in the browser window.

Fit ⇧0: Resizes frames to fit your browser’s viewport, regardless of their size.

Fill Width ⇧1: Automatically resizes frames to fill the width of your browser window during playback. This helps avoid blank space around narrower frames and ensures your prototype stays responsive as you resize the window.

Actual Size z: Displays frames at their actual size, regardless of your browser’s window size.

The web app will use the same preview display setting until you change it.
