pdf-to-pptx

PDF to PowerPoint

Turn a PDF into a deck, one slide per page, at the size the pages were.

Reads: a PDF — application/pdf
Writes: one file — slide decks
Tool page: /pdf-to-powerpoint

Example

Put a printed deck back into slides you can present from.

Given

deck.pdf — an ordinary PDF of 3 pages

From code

            import { loadDocument, runOperation } from '@pagecraft/core';

const deck = await loadDocument({ bytes, name: 'deck.pdf' });

const [output] = await runOperation('pdf-to-pptx', [deck], {
  dpi: 150,
  format: 'png',
});

From a shell

            pagecraft pdf-to-pptx deck.pdf --dpi 150 --format png

What comes back

One slide deck.

This example is run by the test suite. If it stopped being true, the build would fail.

Options

`dpi--dpi`

integer (dpi)

Density

Pixels per inch each page is drawn at. 150 projects well; 300 is print quality.

Default: 150

`format--format`

string, one of

Format

Default: 'png'

png — Lossless, and much larger for a photograph.
jpeg — Far smaller for scans and photographs.

`quality--quality`

integer (%)

Quality

How much detail to keep. Ignored by PNG, which discards nothing.

Default: 90

`background--background`

string, '#rrggbb'

Background

What shows through where the page draws nothing.

Default: '#ffffff'

`pages--pages`

string, a page selection: '1-3, 7, 9-', 'even', 'last'

Pages

Which pages become slides, and in what order: '1-3, 7, 9-'.

Default: 'all'

What it cannot do

Each slide is a picture of a page. Nothing on it can be edited, selected, searched or read by a screen reader — this makes a PDF presentable, not editable.
A deck has one slide size and a PDF need not have one page size. The first page settles it, and a page of a different shape is fitted inside and centred rather than stretched.
A higher density makes a sharper slide and a much larger file: the deck holds one image per page, and doubling the density quadruples it.
Links, form fields and annotations do not survive: they are not part of the picture of the page.
