Import PowerPoint & Google Slides

Astlide reads PowerPoint files: each page becomes an Astlide slide, with its text kept as text and its shapes, pictures and tables in place. Placeholders get their position and text style from the slide layout and master, theme colors and fonts are resolved, and speaker notes, titles and hidden slides carry over.

Google Slides and Keynote work through their PowerPoint export. To write new slides in Markdown with a template’s design, see PowerPoint templates.

Show a .pptx as it is

Put the file in a deck folder, next to your other slides:

src/content/decks/q3-review/
├── _config.json
├── 01-intro.md
├── 02-numbers.pptx      ← every page of it, in place
└── 03-next-steps.mdx

Its pages sort with the other files by name (02-numbers.pptx → 02-numbers--001, 02-numbers--002 …), and presenter view, overview, notes and PDF / PPTX export work as for any slide. Edit the .pptx and the deck follows on save. Pictures and fonts embedded in the file are served by Astlide (from /_astlide/pptx/).

Import into an editable deck

bunx astlide import ~/Downloads/kickoff.pptx --deck kickoff

This writes one .html slide per page to src/content/decks/kickoff/ (title, notes and hidden in frontmatter, one shape per line), pictures to public/pptx/kickoff/, and a _config.json. From then on the slides are plain files: edit them, mix in Markdown slides, change the theme.

Option
--deck <name>	Deck folder name (default: from the file name)
--force	Replace an existing deck folder
--cwd <dir>	Project root (default: found from the current directory)

Google Slides

Pass the deck’s URL. It is downloaded as PowerPoint, which works when the deck is shared as “Anyone with the link”; otherwise download it (File → Download → Microsoft PowerPoint) and import the file.

bunx astlide import https://docs.google.com/presentation/d/1AbC…/edit

From code

import { pptxToSlides } from "@astlide/core/pptx";

const deck = pptxToSlides(await readFile("talk.pptx"), {
  // Where pictures and embedded fonts go (default: pictures inlined as data: URLs).
  media: ({ name, data, type }) => saveSomewhere(name, data, type),
});
deck.slides[0].html;   // an Astlide .html slide body (1920×1080)
deck.slides[0].notes;  // speaker notes
deck.theme;            // the master's theme colors and fonts

What converts

In PowerPoint	In Astlide
Text boxes and placeholders: fonts, sizes, colors, bold / italic / underline, alignment, bullets and numbering, spacing, links	Positioned text
Rectangles, rounded rectangles, ellipses, arrows, callouts, common preset shapes, freeforms	CSS boxes and SVG
Solid, gradient, picture, tiled and pattern fills; outlines, dashes, arrowheads	CSS / SVG
Pictures (PNG, JPEG, GIF, SVG), cropping	<img>
Tables: cell fills, borders, merged cells	<table>
Groups, rotation, flips	Transforms
Backgrounds (slide, layout, master), master and layout artwork	The slide canvas
Embedded fonts	@font-face

Charts, SmartArt and embedded objects show as a marked frame, and EMF / WMF pictures (which browsers can’t display) as an outline — re-insert those as pictures. Slides other than 16:9 are letterboxed.
