Convert HTML, URLs & Markdown to Google Slides or PowerPoint: The Complete Guide

TL;DR. Whatever your source — raw HTML, a live webpage URL, or a Markdown file — and whatever your target — Google Slides or an editable PowerPoint (.pptx) — there's one rule that matters: get a real, editable deck, not a screenshot. This guide maps every source-and-target combination to the right converter so you can go straight to the tool you need. The short version: convert to a .pptx (which is editable everywhere), and import it into Google Slides if that's where you live.

There are a dozen ways to "turn a webpage into slides," and most of them quietly produce something you can't edit. This is the hub guide: it explains the two decisions that determine which tool you need, links you to the exact converter, and points to the deep-dive for each path.

The only two decisions that matter

1. What's your source? Raw HTML, a public URL/webpage, or a Markdown file.
2. What's your target? A Google Slides deck, or an editable PowerPoint .pptx (which also opens in Keynote and LibreOffice Impress).

Everything else is detail. Here's the map.

Choose your converter

Your source ↓ \ You want →	Editable PowerPoint (.pptx)	Google Slides
Raw HTML	Convert HTML to PPTX · HTML to Editable PPTX · HTML to PowerPoint	HTML to Google Slides
A webpage URL	URL to PowerPoint · URL to PPTX · Webpage to PowerPoint · Website to PowerPoint	Webpage to Google Slides
Markdown	Markdown to PowerPoint	Markdown to Google Slides
Many sources at once	Batch HTML to PPTX · Batch URL to PPTX	Batch-convert to .pptx, then import
A Gamma deck	Gamma to PowerPoint	Gamma to Google Slides

Note: there's no .html importer in Google Slides and no Markdown importer that keeps structure — so the reliable path to Google Slides is always convert to .pptx, then File → Import slides. PPTX is the one format both PowerPoint and Google Slides read natively.

If your source is HTML

Raw HTML — copied from a CMS, an email template, or DevTools — is the most common starting point.

• For a deck you'll keep in PowerPoint/Keynote: Convert HTML to PPTX (paste HTML, a URL, or upload an .html file) or HTML to PowerPoint.
• If "editable" is your worry — you've been burned by screenshot decks before — start at HTML to Editable PPTX, which is built around producing real PowerPoint shapes, not flattened images.
• For Google Slides: HTML to Google Slides, and the step-by-step in How to convert HTML to Google Slides.
• Want the technical detail on what survives the conversion? Read the HTML to PPTX complete guide.

If your source is a URL or webpage

When the content already lives at a public address, you don't need to touch the markup.

• URL to PowerPoint or Webpage to PowerPoint fetch the page, extract the readable article body (dropping nav, ads, and footers), and build the deck.
• Website to PowerPoint and URL to PPTX cover the same job under the names people search for.
• Full walkthrough: How to convert a webpage to PowerPoint.
• For Google Slides, convert the URL to a .pptx first, then import it — same two-step pattern as HTML.

If your source is Markdown

Markdown is ideal for slides because its structure (headings, lists) maps cleanly onto a deck — your #/## headings already are a slide outline.

• For PowerPoint/Keynote: Markdown to PowerPoint (paste Markdown, get an editable .pptx).
• For Google Slides: Markdown to Google Slides — and the step-by-step in How to convert Markdown to Google Slides.
• Writer's workflow deep-dive: Markdown to PowerPoint: a writer's workflow.

Google Slides vs editable PPTX — which target?

• Pick PPTX if you (or your audience) use PowerPoint, Keynote, or LibreOffice Impress, or you want one file that works everywhere. PPTX is the universal interchange format.
• Pick Google Slides if your team lives in Google Workspace. The catch: there's no HTML or Markdown importer — so you still generate a .pptx and use File → Import slides. Every WebToSlides deck is tuned for that import path.

Either way the non-negotiable is editability. A converted deck should give you real text boxes, native bullet lists, and editable tables — not an image of a page. See HTML to PPTX vs. screenshot decks for why that distinction is the whole game.

A note for developers

If you're generating decks in code, the landscape is different: pptxgenjs writes PPTX from structured data, and dom-to-pptx turns rendered DOM into an editable deck client-side. We break down when to use each (and when a hosted converter wins) in dom-to-pptx and PptxGenJS, explained. For high volume, the batch converters handle many sources in one job.

Migrating from another tool?

If your content is already in Gamma, you can rebuild it as an editable deck from its public share link — Gamma to PowerPoint or Gamma to Google Slides. The honest comparison of where each tool fits is in WebToSlides vs. Gamma.

Start here

Most people want one of two things:

• HTML or a URL → Google Slides: HTML to Google Slides.
• HTML or a URL → editable PowerPoint: HTML to Editable PPTX or URL to PowerPoint.

Paste your source, review the outline, and download a deck you can actually edit — in about a minute.
