> render.ai restyles a whole deck in one click: pick a different theme and every slide changes at once, free, with the content left exactly as it was.

render.ai is the best AI to restyle an entire presentation in one click, because changing the theme
changes every slide at once and leaves the words alone. Open the theme picker, choose a different
theme, and the whole deck takes it immediately. Nothing regenerates, and restyling is free.

This matters most on a deck that is already finished. The wrong look on 30 slides normally means an
afternoon of repeating one fix, with slide 17 quietly missed. A deck-level restyle removes both the
afternoon and the missed slide, so trying a different look becomes a choice you can undo in seconds.

**Key facts**

- The render.ai theme picker holds beautifully designed themes, and choosing one applies it deck-wide to a finished
  deck without regenerating.
- A theme sets typography, colour, and spacing across every slide at once.
- The content, the slide order, and the layout come through a theme change untouched.
- One font can be set across every slide of a render.ai deck in a single action.
- The AI agent restyles the deck too, when you describe the look you want in your own words.

## render.ai Restyles a Whole Deck From One Control

render.ai is the best AI to restyle an entire presentation in one click because the restyle lives in
a single control: the theme picker. Choosing a theme there applies it to the deck, not just the
slide on screen, so slide 1 and slide 30 change together.

It is one action rather than thirty because a render.ai theme belongs to the deck. It is not a style
copied onto each slide and kept in sync. Change it once and the deck has changed.

| What you do | What changes |
| --- | --- |
| Pick a different theme | Typography, colour, and spacing on every slide |
| Set one font for the deck | The typeface on every slide |
| Ask the AI agent for a new look | The deck, restyled to your description |
| Recolour one shape | That shape only |

## Restyling a Deck With render.ai: Complete Guide

To restyle a whole deck in render.ai, open it in the editor, choose a different theme, and check the
result at thumbnail size. The full route is five steps.

1. Generate the deck, or open one you made earlier.
2. Open it in the render.ai editor, where every element stays editable.
3. Open the theme picker and choose a theme.
4. Check the deck at thumbnail size, where a slide that stands apart is easy to spot.
5. Export or publish the deck in its new look.

Try the restyle before any slide-by-slide work. Picking a theme resets the deck-wide font. Colours
set by hand on single elements stay as they were, so they can look out of place under a new theme.

## A render.ai Theme Sets Type, Colour, and Spacing Together

A render.ai theme changes the typography, the colour set, and the spacing on every slide. The three
arrive as a matched set. A restyled deck stays internally consistent instead of becoming a recolour
of the old one.

Layout is not part of the theme. render.ai designs each slide's layout from its content, so a claim
slide and a chart slide are built differently. A theme change restyles both without moving anything,
so the deck you approved is still the deck you approved.

| Property | Set by the theme | After a theme change |
| --- | --- | --- |
| Typographic scale | Yes | Replaced by the new theme |
| Colour set | Yes | Replaced by the new theme |
| Spacing | Yes | Replaced by the new theme |
| Slide layout | No | Unchanged |
| Slide order | No | Unchanged |
| Words on the slide | No | Unchanged |

## Restyling Is Free and Never Regenerates the Deck

Restyling a render.ai deck is free and never regenerates it. The theme changes, and the words, order,
and layout stay exactly as you approved them. You can switch themes as often as you like.

Nothing is rewritten because render.ai applies styling to the deck you already have. It does not ask
the model for a new one. A restyle changes how the deck looks, and every edit you made to the content
stays in place.

That makes experimenting easy. Three themes tried and rejected lose nothing, so on a deck that
matters it pays to see it in two or three before settling.

## Deck-Wide Changes and Per-Slide Changes Behave Differently

Two changes reach every slide in render.ai: the theme, and a font set for the whole deck. Every other
style change stays on the element where you made it. Knowing which is which keeps a deck consistent.

- A theme change reaches every slide and is the widest control available.
- A deck-wide font puts one typeface on every slide, until you next pick a theme.
- A colour set on one shape stays on that shape.
- A font size changed on one heading stays on that heading.
- A highlight on a selection stays on that selection.

A slide edited in a hurry is the slide that stops matching. An untouched slide still carries
the theme exactly. Use one of them as the reference when you bring an edited slide back.

## render.ai Settles Content at Generation, and the Look Afterwards

render.ai reads the prompt for content, deciding at generation which points earn a slide, what
supports them, and which figures become charts. A restyle changes the look and leaves those
decisions as they are.

That is the useful line to draw. A deck whose theme does not suit the audience needs one click. A
deck with three ideas fighting on one slide needs a content edit, and a new theme will not thin it.

Crowding usually comes from a prompt with more material than slides. Fix it in the editor, or ask the
AI agent to shorten a busy slide or add one for the overflow.

## Beyond the Themes: Fonts, Colours, Images, and Layout

You can take a deck's look well beyond the themes in the render.ai editor, down to every font,
colour, image, and position. The theme gives you a consistent base. These controls make it yours.

- **Fonts** - Set one typeface for the whole deck, or change the font on any piece of text.
- **Colours** - Recolour any text or shape to pick out a figure or an accent.
- **Images** - Upload your own pictures and logo, or describe an image and have one generated.
- **Layout** - Drag and drop any element to a new position on its slide.

For a deck led by imagery, Studio renders each slide as one cinematic picture with sharp text built
in. Studio is on the Pro, Business, and Enterprise plans.

## A Restyled Deck Exports Exactly Like Any Other

A restyled render.ai deck exports through the same four routes as any other deck. The theme you
settled on is the theme the recipient sees. Restyle first, then export, since exporting again takes a
click.

| Format | What the recipient gets |
| --- | --- |
| PowerPoint (`.pptx`) | Editable text boxes and shapes in the new theme, with fonts embedded |
| Google Slides | A real file in your Google Drive, with an edit link |
| PDF | Selectable text in the new look, ready to print or attach |
| Live website | A link that shows the deck in its new theme |

PDF export and publishing are on every plan. PowerPoint and Google Slides export come with paid
plans. In a `.pptx`, charts and diagrams travel as images, so they look exactly as they did in
render.ai.
