Each page is rendered and placed on a slide, so the deck looks exactly like the PDF. The slides hold pictures, not editable text boxes, and the page says so before you start.

Every page you choose becomes one slide, centred and scaled to fit without distortion. Open the file in PowerPoint, Keynote, Google Slides or LibreOffice Impress and you can present it immediately, add slides around it, reorder it and write notes under each slide.
What you cannot do is click into the text and change a word, because there is no text box - each slide holds a picture of the page. This is not a limitation we chose so much as one we are being straight about: turning a PDF page back into editable shapes, text boxes and charts is guesswork even for expensive desktop software, and a browser doing it would produce something you would spend longer fixing than rebuilding.
If editable text is what you need, PDF to Word in "editable text" mode gives you the words in a document you can work with, and you can paste from there into slides you lay out yourself.
16:9 is the shape of every modern screen and projector, and it is the default. A portrait PDF page placed on a 16:9 slide will have space either side of it; that is unavoidable, because a tall page cannot fill a wide slide without being cropped.
4:3 suits older projectors and some printed handouts. "Match the PDF" makes the slide exactly the shape of the pages, so a portrait document gives you portrait slides with the page filling them completely - the right choice when the pages must not be boxed in, such as a scanned form or a poster.
PowerPoint refuses slides larger than 56 inches on a side, so very large pages are scaled down to stay within that while keeping their proportions exactly.
The resolution decides how many pixels each page picture holds. At 150 dpi a slide looks clean on any laptop or television. At 200 to 300 dpi it stays sharp when a projector enlarges it onto a wall, or when someone zooms in during a video call.
The cost is size. Each page is a photograph, so a forty-page PDF at 300 dpi can produce a .pptx of well over a hundred megabytes, which is awkward to email and slow to open. Converting at 150 dpi and raising it only if the result looks soft is the sensible order.
The pictures are saved as JPEG by default, which is right for pages with photographs or shading. For pages that are pure line art and text, PNG keeps the edges crisper at the cost of a larger file.
Files are not uploaded - everything happens in your browser. The PDF is rendered page by page in this tab and the PowerPoint file is assembled in memory before being handed to your downloads folder.
Two libraries are needed for that - one to read PDFs and one to write .pptx files - so they are fetched on demand, once, after you choose a file. Together they are about 1.6 MB, and your browser caches them afterwards.
Pages are converted one at a time with progress shown. On a phone that keeps memory use flat rather than building a whole deck of images at once.
If you have pictures that need to become slides, JPG to PPTX does the same job starting from images - useful for photographs of a whiteboard or a set of charts exported from another program.
And if what you want is a PDF of a deck rather than a deck from a PDF, printing to PDF from PowerPoint gives a better result than any converter, because the application knows the real layout.
A common reason people end up here is that the original presentation has been lost and only the exported PDF survives. In that situation this tool gets you back to something presentable in seconds, and it is often enough: you can add new slides, reorder them, hide the ones you do not need and write speaker notes under each one. Only the words printed on the old slides stay fixed.
If you also need those words, convert the same PDF with PDF to Word in editable text mode and keep both files open. Rebuilding three slides by hand with the text in front of you is quicker than fighting a converter that half-guesses the layout, and the result is a deck that behaves properly rather than one full of oddly grouped text boxes.
Choose the PDF, pick a slide shape, and press Convert. You get a .pptx with one slide per page.
No. Each slide holds a picture of the page. For editable words, use PDF to Word in editable text mode.
16:9 for a modern screen or projector. "Match the PDF" when the pages must fill the slide completely without boxing.
Because every slide is a picture. Convert at 150 dpi instead of 300, and choose JPEG rather than PNG.
Yes. It is a standard .pptx file, which all of them read.
Yes. Type the pages you want, such as 1-5,9. Leave the box empty for every page.
