Rollpie Slide is a free slide editor that runs in your browser with no install. Drag across an empty part of the slide to place a text box, then start typing right away. Drag a box to move it, and use the handles to resize it. Double-click to edit its text again.
Scroll the wheel to zoom smoothly around the pointer. Hold the space bar and drag, or drag outside the slide, to pan the view. Click the number in the bottom bar to fit the slide back to the window.
The Slides panel adds more slides and sets the background gradient from three colors and an angle, plus the accent color. The Text panel adjusts font size, line height, color, bold, italic and underline; the Transform panel sets the position and size of the box. Save your deck as JSON from the File panel and load it back later.
Double-click a panel title to switch how the panels are laid out. In the movable layout you drag panels wherever you like and keep several open at once; in the fixed layout a single panel sits in the top right.
