Before someone understands your presentation, they react to it. That reaction, the feeling a deck creates before anyone has read a word, is now something you can control.

Effects transforms your presentation into a high-resolution, styled deck while aiming to preserve its message. When you apply an Effect, Napkin uses your existing slides as the starting point. What changes is the aesthetic: the texture, material, and visual feeling of the deck.

The Effects panel opens, showing the available preset styles and a custom description field.

You can apply an effect to a single slide, or your entire presentation at once with one click.

Napkin offers a range of preset styles, including Ink Story, Whiteboard, Working Doc, Soft Pitch, Sticky Notes, Marker Workshop, and more. Each creates a distinctly different aesthetic, from hand-sketched to whiteboard-style to polished studio work, so you can find the right feeling for any deck.

If none of the preset styles match what you have in mind, use the "Describe your effect" field to describe your own. The more specific your description, the better. Reference tone, material, mood, and context, for example: "Polished and professional, with readable labels and clear headings. It should feel ready for a leadership review."

All three are selected by default. Deselect any you'd like to leave untouched. Whichever elements you apply the Effect to become part of the styled image and are no longer individually editable. Elements you leave unchecked stay fully editable. Deselect Text, for example, and your text remains editable after the effect is applied.

Review the styled slides for changes to text, numbers, and details before sharing. Turn off an Effect to return to the original slide.
