A deck anyone can open
A PDF needs no PowerPoint licence and no Office app. It opens in a browser, on a phone or on a Linux laptop, which helps when you share a deck with someone who only has a viewer.
PPTX to PDF Converter
Turn a PowerPoint deck into a PDF with one page per slide, ready to email, upload or print.
To convert pptx to pdf, add the PowerPoint file, keep PDF as the output and download the result. Each visible slide becomes one fixed page that opens without PowerPoint on a phone, a Chromebook or a shared computer. Before you send it, know four things: hidden slides and speaker notes are left out, there is no slide-range option, fonts the server lacks are replaced, and a web link did not survive in our test.
Transfers use HTTPS, and files converted on the free tier are deleted after 24 hours, so the result is not a long-term archive. Quality depends on the source file, so open the PDF file once before you share it.

PPTX (Office Open XML Presentation)
The Microsoft PowerPoint presentation format, an Open Packaging Conventions package of XML parts defined by the Office Open XML standard (ISO/IEC 29500, ECMA-376). Slides, layouts, notes and animations are stored as editable parts, so how a deck looks depends on the fonts and features of the program that opens it.

PDF (Portable Document Format)
A fixed-layout document format published as ISO 32000. Each page records the exact position of every character, image and line, usually with the fonts embedded, so it displays and prints identically in any reader and is awkward to edit.

Why use indox to convert PPTX to PDF?
One slide, one page
Each visible slide becomes one page of the PDF, in the same order as the deck. You can attach, upload or print it without worrying that someone else's PowerPoint will rearrange it.
Several decks in one visit
Add more than one presentation from your device, Dropbox, Google Drive or a URL. Each file is converted to its own PDF, so a stack of lecture decks can be done in one session.
What happens to your presentation
Stays
- The visible slides, in their original order, one per page
- Your original PPTX, which is not touched
- The look of each slide as the server drew it, fixed on the page
Changes
- Hidden slides: they are left out of the PDF
- Speaker notes: they are not exported
- Animations, transitions, audio and video: a page shows one still state
- Fonts the server lacks: they are replaced by similar ones, such as Calibri by Carlito
- Web links: the one in our test deck was lost
How do I convert PPTX to PDF online?
- 1
Check the deck before you upload
Unhide any slide you want in the PDF and copy the notes you need somewhere else, because neither the hidden slides nor the notes will be exported.
- 2
Add the PPTX and choose PDF
Drop the file on the box, or add it from Dropbox, Google Drive or a URL. Pick PDF as the output and start the conversion. There are no further settings to change.
- 3
Download and flip through the PDF
Compare the page count with the number of visible slides. Then check the slides that use unusual fonts, tight text boxes or links, and open the PDF in the viewer your audience will use.
What do I get from indox's PPTX to PDF converter?
You get a plain PDF of the visible slides, produced the same way for every deck. The conversion runs on indox servers using LibreOffice, so you do not need PowerPoint or the right fonts on your own computer. There are no options to set. The trade-off is that the server may not have the fonts your deck uses, and that you cannot ask for notes pages, hidden slides or a slide range. Keep the PPTX as the file you edit and send the PDF as the copy people read.
- One PDF page for every visible slide
- Works from a phone, tablet or any computer with a browser
- Add files from your device, Dropbox, Google Drive or a URL
- No PowerPoint needed on your side
- Limits stated before you convert
What are the limits for PPTX to PDF?
Size
The upload box shows the live size limit before you add a file. Signing in raises it; a paid plan does not change it.
Formats
PPTX in, PDF out. Pick another output on the converter if you need a different format.
Privacy
Files are encrypted in transit over HTTPS and processed on indox infrastructure.
Deletion
Free-tier files are kept for 24 hours after the job finishes, then deleted automatically.
Limits worth knowing
- Hidden slides are not exported, and there is no setting to include them. Unhide them in PowerPoint first.
- Speaker notes and handout layouts are not exported, and there is no setting to add them. Copy the notes elsewhere if you need them with the slides.
- There is no slide-range option. The whole deck is converted, so delete or move any slides you do not want to share before uploading.
- Fonts the server does not have are replaced with similar ones, and the substitute is embedded in the PDF. Calibri became Carlito in our test, which keeps line breaks; a script font such as Segoe Script became Noto Sans, which looks different.
- Animations, transitions, embedded audio and video do not work in the PDF, which keeps one static image of each slide.
- Web links may not stay clickable. In our test the web link was lost, and only the link to another slide survived.
When the result is not what you expected
| What you see | Why | What to do |
|---|---|---|
| The PDF has fewer pages than the deck has slides | Hidden slides are not exported | Unhide the slides in PowerPoint and convert again |
| The text looks different or wraps in new places | A font used in the deck is not on the server and a substitute is wider or narrower | Switch the deck to a widely installed font such as Arial and convert again |
| The speaker notes are missing | The conversion exports slides only, with no notes pages | Copy the notes into a separate document, or print notes pages from PowerPoint |
| A web link does not open | In our test the web link was not kept, and only the slide-to-slide link was | Open the PDF and test every link, and add the missing ones in a PDF editor |
| I need the PDF as a Word file | A PDF holds fixed positions and is not meant for editing | Use PDF to DOCX, and expect to tidy the layout |

PPTX to PDF FAQs
How do I convert PPTX to PDF on a Mac, iPad or phone?
Open indox.org in the browser on that device, add the PPTX from the device, Dropbox, Google Drive or a URL, choose PDF and start the conversion. Nothing needs to be installed, and the PDF is downloaded when it finishes. Large decks are easier to handle on a computer.
Will my fonts stay the same?
Not always. The conversion runs on a server, and a font that is not installed there is replaced by a similar one before the PDF is made. In our test Calibri became Carlito, which has the same letter widths, so lines broke where they did in the deck. Arial became Liberation Sans, and Segoe Script, which the server lacks, became Noto Sans. The substitutes are embedded, so the PDF looks the same everywhere. If a font matters, switch the deck to a common one such as Arial and convert again.
Are speaker notes included in the PDF?
No. The conversion exports the slides only, and there is no option to add notes pages or handouts. If your reader needs the notes, copy them into a separate document or print notes pages from PowerPoint itself.
What happens to hidden slides?
They are left out. A slide hidden in PowerPoint has no page in the PDF, so the PDF can have fewer pages than the deck has slides. To include one, unhide it in PowerPoint and convert again.
Can I convert only some of the slides?
Not on indox. There is no slide-range setting, so the whole deck is converted. Delete the slides you do not want, or save a copy of the deck with only the slides you need, then upload that.
Will animations and transitions carry over?
No. A PDF page is a still image of the slide, so build-by-build animations, transitions, audio and video do not play. Every slide appears in its finished state.
Will the links in my slides still work?
Not all of them. In our test the web link in the deck was lost, and a repeat run gave the same result. The link from one slide to another survived. Open the PDF and click every link you depend on, and add the web links you need in a PDF editor if they are missing.
Why does my PDF have a different number of pages from my slides?
The most common cause is a hidden slide, which is not exported. Count only the visible slides in PowerPoint. If the numbers still differ, check whether a slide was removed or added after you saved the file.
Does the PDF open the same everywhere?
The layout is fixed, so every PDF viewer draws the same pages. The fonts the converter chose are embedded in the PDF, so a substituted font is what everyone sees, on every device.
How long does the conversion take?
In our test a 12-slide deck of 65 KB took 21.4 seconds on the first run, which started cold, and 4.9 seconds on a repeat. Your time will depend on the deck and on how busy the server is.
