How this works in your browser
Each PDF page is rendered to a high-resolution image through PDF.js, and PptxGenJS builds a .pptx placing one image per slide at 16:9 widescreen dimensions with the page scaled to fit. It is worth being clear that this is a presentation wrapper around page pictures rather than a structural conversion: no attempt is made to turn paragraphs into text boxes or tables into slide tables, because inferring that reliably from positioned PDF fragments is a much harder problem than it appears and tends to produce a mess you spend longer fixing than rebuilding. What you get instead is dependable: every page appears exactly as it did, on a canvas you can annotate freely.

Common ways to use PDF to PowerPoint
Annotating a document in a meeting
Drop arrows, callouts and comments onto report pages while presenting, without altering the source.

Building a review deck
Turn a design or document into slides you can walk a client through page by page.
Frequently asked questions
Can I edit the text on the slides after conversion?
Each slide is a page image, not extracted text. You can add new text boxes and shapes in PowerPoint, but the original page content is a picture rather than editable text.
What slide size is used?
Slides are created at the standard 16:9 widescreen size (13.33 × 7.5 inches). PDF pages are scaled to fit.
Is there a page limit?
No hard limit. Large PDFs with many pages will produce larger .pptx files and may take longer to process in the browser.
So what am I actually able to edit?
Everything you add on top: text boxes, arrows, callouts, highlights and extra slides. What you cannot do is click into the original page and retype a sentence, because that page is an image. Think of it as getting a slide-shaped canvas with your document already on it.
Why is the file so much bigger than the PDF?
Because a compact vector PDF page becomes a high-resolution bitmap on each slide. Rendering at a resolution that stays sharp on a projector inevitably costs far more bytes than the original description of the page did.
What if my PDF pages are portrait?
Slides are built at standard 16:9 widescreen and portrait pages are scaled to fit, which leaves space on either side. That is expected: you can use the margins for annotations, or crop the PDF first if you want a tighter fit.
Is my document uploaded anywhere?
No. Rendering and .pptx generation both happen inside your browser tab.
