Frequently asked questions

What is actually inside a PPTX file?

A .pptx file is not one document but a ZIP archive of XML parts — one for the text, others for styles, images and relationships. Rename it to .zip and you can open it up and look.

Are my files uploaded to a server?

No. Your PPTX file is read and the PDF is built entirely inside your browser, so nothing ever leaves your device.

Can I convert several files at once?

Yes. Add as many PPTX files as you like and download the PDFs one by one, or all together as a ZIP archive.

Will the layout look exactly like the original?

The text, headings, lists and tables carry over and are laid out onto clean A4 pages. This is a content-faithful conversion rather than a pixel-perfect copy of the original formatting.

Is there a file size or file count limit?

No. Everything runs on your own device, so the only practical limit is how much memory your browser has available.

Do I need to install anything?

No. There is nothing to install and no account to create — the converter runs in any modern browser, on desktop and mobile alike.

Does each slide become one page?

Yes — one landscape page per slide, in presentation order, so the PDF's page numbers line up with your slide numbers. That correspondence is deliberate: it means you can refer someone to "page 12" and land on slide 12.

Are speaker notes included?

No. Notes are stored in a separate part of the .pptx from the slides themselves, and this converter reads the slides — which is normally what you want when circulating a deck, since notes are often written for you rather than for your audience. PowerPoint's own export can produce a notes handout if you need one.

What happens to my images and charts?

They are not carried over; the text comes through and the visuals do not. For a text-led deck that loses very little, but for a design-led pitch it loses most of the point — reproducing slide graphics faithfully means running PowerPoint's layout engine, which does not exist in a browser tab. Export from PowerPoint for those.

What happens to animations and transitions?

They are flattened away, which is unavoidable — a PDF page has no timeline. A slide with items that appeared one click at a time becomes a single page showing all of them, which is almost always the right way to read a deck on paper.

Can I convert a .ppt file?

Not here. .ppt is the pre-2007 binary format, a different thing from .pptx rather than an older version of it. Open it in PowerPoint, LibreOffice Impress or Google Slides and save as .pptx, then convert that.

Is my presentation uploaded?

No. The archive is unzipped and parsed in your browser and the PDF is assembled on your device. Nothing is transmitted, so an unreleased roadmap or a board pack stays where it started.

PowerPoint files are shared more often than they are presented. A deck sent to someone who will read it at their desk does not need transitions and builds; it needs to open, on any device, without the recipient owning PowerPoint and without the layout drifting because their laptop lacks the font you used. That is a PDF.

Inside a .pptx — again a ZIP archive of XML — each slide is its own file under `ppt/slides/`, and within a slide the text sits in shapes. Some of those shapes are placeholders with a declared role, which is how the converter can tell a slide's title from its body text without guessing at font sizes.

Each slide becomes one landscape page carrying that slide's text, with its title set as a heading. Slides come through in presentation order, numerically, so slide 10 follows slide 9 rather than sorting itself next to slide 1.

How to convert PowerPoint to PDF

Add your .pptx decks
Drop them in or pick them. Several at once is fine — each becomes its own PDF. The older .ppt format is not readable here; see below.
Convert
Every slide file in the archive is parsed and its text shapes are read in order, with title placeholders marked as headings. The pages are landscape, matching the shape people expect a deck to be.
Download
Save the PDF. Nothing was uploaded — the deck was unzipped and read in your own browser, which matters for an unannounced product roadmap or a board pack.

What a converted deck contains

One page per slide: In presentation order, laid out landscape. The page count matches your slide count, which makes the PDF easy to talk through against the original.
Slide titles: Rendered as headings. A .pptx marks title placeholders explicitly in the slide XML, so this is read from the file's own structure rather than inferred from which text happens to be biggest.
Body text and bullets: All text from the slide's shapes, in the order the shapes appear in the file. Note that this is document order, not visual order — a text box added late but positioned at the top of the slide will appear where the file puts it, not where the eye finds it.
Speaker notes: Not included. Notes live in a separate part of the archive from the slides, and the converter reads the slides. This is usually what people want from a deck they are circulating; if you need a notes handout, PowerPoint's own export produces one.
Images, charts and diagrams: Not carried over. A slide built entirely from a SmartArt diagram or a chart will come through with only its text, which for a heavily visual deck may be very little. That kind of deck is better exported from PowerPoint itself.
Animations, transitions and builds: Gone, necessarily — a PDF page has no timeline. A slide with five sequential reveals becomes one page with all five items on it, which is generally the sensible flattening.

Text-led decks convert well; design-led decks don't

It is worth knowing before you start which kind you have. A conference talk, a lecture, a status update, a training deck — these are mostly words arranged in a hierarchy, and they come through with that hierarchy intact and readable.

An investor pitch, a marketing deck, anything where full-bleed photographs and carefully placed diagrams carry the argument — these do not. What survives is the text, and if the text was deliberately sparse because the pictures were doing the work, the result will look sparse.

There is no way around this in a browser: reproducing a slide's design means reproducing PowerPoint's layout, theme inheritance, master slides and typography, which is a rendering engine, not a parser. Where the design is the deliverable, use File → Export in PowerPoint.

.pptx and .ppt

The x matters. `.pptx` arrived with Office 2007 and is Office Open XML, an open standard that any program can read by unzipping it. `.ppt` is the binary format that came before, and reading one correctly means implementing an undocumented structure that Microsoft itself moved away from.

If you have a .ppt, open it in PowerPoint, LibreOffice Impress or Google Slides and save it as .pptx. All three handle the upgrade properly, and the converted file will then work here.

About the PPTX format

.pptx is the presentation format Microsoft introduced in 2007. It is published as an open specification under the name ECMA-376 / ISO/IEC 29500, so a file can be read without the program that wrote it.

A .pptx file is not one document but a ZIP archive of XML parts — one for the text, others for styles, images and relationships. Rename it to .zip and you can open it up and look.

Files like this usually come out of Microsoft PowerPoint, Google Slides, and LibreOffice Impress.

What comes through

slide text
slide order
heading levels
bulleted and numbered lists
embedded images

What does not

animations and transitions
speaker notes
the exact page design
embedded fonts

Worth knowing

Because the format is an open, published one rather than a proprietary blob, a {ext} file can be read by LibreOffice, Google Docs, Apple's iWork apps and this page alike — none of them needs Microsoft Office installed to make sense of it.
Slides are laid out landscape at the deck's own aspect ratio, so a 16:9 presentation does not end up letterboxed on a portrait page.
One slide becomes one page, in the order the deck had them.
