Someone sends you a deck as a PDF and you need to change two words on slide 14. Or you have a report and want three of its pages as slides for Monday's meeting. A PDF won't let you do either comfortably, so the practical answer is to turn it back into a .pptx file.
PDF to PowerPoint makes one slide per PDF page. It asks you to choose between slides you can edit and slides that look exactly like the PDF. The choice matters, so it helps to know what each option does.
A PDF doesn't remember it was a presentation
When PowerPoint, Keynote or Google Slides exports a PDF, it throws away most of what made the file a presentation. Text boxes, placeholders, the slide master, charts linked to data, animations and transitions are all gone. What's left is a page of drawing instructions. Draw this photo here. Fill this rectangle blue. Write "Revenue" at this position in 28 pt Calibri Bold.
So no converter can hand you the original deck back. What it can do is read those instructions and rebuild something close. EddiesPDF reads every piece of text on the page along with its position, font, size and colour, and whether it's bold or italic, then groups the pieces into lines and paragraphs. Everything that isn't text (photos, logos, shapes, chart bars, table lines) gets drawn as a picture.
Editable text or exact look
Under "Slides" there are two options.
"Editable text" is the default. Each page is drawn as an image with its text left out, and that image becomes the slide background. The text then goes back on top in real PowerPoint text boxes, at the position it had on the page, with the same size, colour and bold or italic styling. One paragraph becomes one text box. Rows that look like a table get one text box per cell, so the columns stay lined up.
"Exact look (pictures)" makes each slide a single picture of the page, text included. It looks identical to the PDF in any app, but you can't change a word.
My rule of thumb: pick "Editable text" if you're going to change wording, and "Exact look (pictures)" if you only need to show the pages.
One thing about editable mode surprises people. The background is one flat image. You can move and edit the text, but a photo, a logo or a bar chart is part of that picture. You can't drag it, recolour it or change the chart's numbers. To replace a picture you'll have to cover it with a shape or a new image. Extract images can pull the original photos out of the PDF if you want them back as separate objects.
Converting a PDF to slides on EddiesPDF
The conversion runs in your browser and the PDF isn't uploaded. A password-protected file asks for its password first.
- Open PDF to PowerPoint and drop your PDF on the page, or click to choose it.
- Under "Slides", choose "Editable text" or "Exact look (pictures)".
- To convert only some pages, type a range in "Pages", like 3-5, 9. Leave it empty for the whole document.
- Optionally, open "More options" and set "Image quality" to "Standard (2000 px)" or "High (3200 px)".
- Click "Convert to PowerPoint", wait for the page counter to finish, and download the .pptx file.
The file keeps the PDF's name with .pptx on the end. It opens in PowerPoint, and in other apps that read .pptx, such as Keynote, or Google Slides once you've uploaded it to Google Drive.
Which image quality to pick
"Image quality" sets how big the page pictures are: the longest side is 2000 pixels on Standard and 3200 on High. 2000 pixels is plenty for a projector or a laptop screen. I'd only switch to High if the slides will be printed large or if the background has fine print people will zoom into, because it makes the file noticeably bigger.
Slide size comes from the PDF
The slides take the size of the first page you convert. A PDF exported from a 16:9 deck gives you 16:9 slides again. An A4 report gives you tall A4-shaped slides, which fits the content but looks odd on a widescreen projector. If later pages are a different size, each one is scaled to fit inside the slide and centred.
PowerPoint only allows slides between 1 and 56 inches on a side, so a poster-sized page is scaled down to fit.
If you want portrait report pages on your own widescreen slides, convert with "Exact look (pictures)", then copy the slides you need into your deck and resize them. That's usually less work than rearranging dozens of text boxes.
Scanned PDFs don't give you editable text
A scan is a photo of paper. There's no text in it to put into text boxes, so even in "Editable text" mode a scanned page comes out as a picture of the page.
Running the scan through OCR PDF first adds an invisible layer of recognised text. PDF to PowerPoint keeps that text invisible on the slide as well: the scan stays as the background and fully transparent text boxes sit on top. That's handy for searching the deck, but not for rewording a slide, because changing hidden text doesn't change what people see. For a scan you need to rewrite, OCR followed by PDF to Word is a better route, and the guide to making a scanned PDF searchable covers the OCR settings.
The same goes for handouts printed with several slides per page. You get one PowerPoint slide per handout page, not one per original slide.
What to check before you present
Editable slides deserve a quick pass in Slide Show view. These are the usual problems:
- Fonts. Each text box asks for the font the PDF used, by family name. If that font isn't installed on your computer, PowerPoint substitutes another, and a wider font can push a line past the edge of its box. Install the font or switch to one you have.
- Separate boxes. Each paragraph is its own text box, so adding a sentence to one won't push the box below it down. After bigger edits, move things by hand.
- Line spacing. Spacing is copied from the PDF as a fixed value. If you make the text larger, increase the spacing too, or the lines will overlap.
- Text that stays in the picture. Some PDFs store headings or logos as outlines (shapes) instead of letters. Those stay in the background image and can't be edited.
The most common slip is fixing slide 14 and never looking at slide 15. Click through every slide once, on the computer you'll present from, before the meeting.
