How it works

How to turn a PDF into PowerPoint slides

Each page is drawn as a picture and placed on its own slide, filling it edge to edge, so the deck looks exactly like the PDF. It’s ready to present straight away, but the words on it can’t be edited.

    Drop in the PDF you want as slides.

  2. 02

    Convert

    Altto renders each page and builds a .pptx, locally.

    Get back a PowerPoint file, ready to present or edit.

Tips

Tips for presenting a PDF as slides

Every slide is a picture of a page, so a little preparation makes the deck easier to present and to update.

  • Convert only the pages you’ll showA 40-page report makes a 40-slide deck. Pull out just the pages you want to present with Extract PDF Pages first, and the deck is smaller, quicker to build and easier to click through.
  • Update a slide without retyping itThe words in the page picture can’t be edited, but you can cover them. Draw a text box over the old wording, give it a fill that matches the page and type the new text on top; the page image stays underneath as the background.
  • Rehearse in Slide Show viewText sized for reading on paper can be hard to make out on a projector. Run through the deck in Slide Show view before presenting, and for a busy table or chart, duplicate the slide and use PowerPoint’s picture Crop tool to show just that part, larger.
  • Add links back by handWeb addresses and links in the PDF become part of the picture, so they can’t be clicked during a slideshow. Where you need one, draw a small shape or text box over it and add the address with Insert → Link.

Like every Altto tool, this runs on your device — nothing you add is uploaded. How Altto works

16:9

is the shape of PowerPoint’s standard widescreen slide. Converted slides take the shape of your PDF’s first page instead, so a portrait A4 report gives tall, narrow slides, which is worth checking before you present on a wide screen.

FAQ

Frequently asked questions

What to expect from a deck built from page images. Need to go the other way? See PowerPoint to PDF.

Will the text be editable in PowerPoint?
No — each slide is a full-page image of that PDF page, so it looks right but the text itself isn’t individually editable. This keeps layout, fonts and images pixel-accurate without a heavyweight reconstruction engine.
How many slides will I get?
One slide per PDF page, in order.
Will image quality be good enough to present with?
Yes for typical documents and slides — pages are rendered at a resolution well above standard screen sharing quality.
Can I convert a password-protected PDF?
No, encrypted PDFs can't be read in the browser. Remove the password first (see our Unlock PDF tool if you own the file), then convert it here.
What if my PDF has pages of different sizes?
The whole deck uses one slide size, copied from the first page. Each later page is placed at its own size from the top-left corner, so a bigger or sideways page can spill off its slide, and a smaller one leaves a gap. For a mixed document, split the odd pages into their own file and convert them separately.
Can I open the deck in Google Slides or Keynote?
Yes. It’s a standard .pptx file, and because each slide holds only a picture of the page, there are no fonts or layouts for another app to get wrong. For Google Slides, upload it to Google Drive and open it from there; Keynote opens .pptx files directly.
Can I turn the deck back into a PDF with Altto?
Not usefully. Altto’s PowerPoint to PDF works by reading the text on each slide, and these slides contain only pictures, so every page would just say it found no readable text. Keep your original PDF, or use PowerPoint’s own File → Export → Create PDF.
