Does each slide become a PDF page?

Yes. The converter maps slides to pages one-to-one and keeps the presentation's order, so page 3 of the PDF is slide 3 of the deck.

Are animations, transitions or speaker notes included?

No. PDF is a static format, so animations, transitions, embedded media and speaker notes are not carried over. Complex effects may be simplified to a static equivalent.

Will the PDF keep my slide size?

Yes. Pages are created at the slide's own dimensions, so a 16:9 deck produces widescreen pages and a 4:3 deck produces 4:3 pages rather than being letterboxed onto A4.

Can I convert more than one PPTX at a time?

No — the tool works on one presentation at a time. Convert a deck, download the PDF, then start over with the next file.

What about fonts that are not installed?

Text is drawn with the closest available font in your browser. Common fonts render as expected, but rare or licensed typefaces may be substituted, which can slightly change spacing.

Why does my converted slide look slightly different?

PowerPoint features such as SmartArt, 3D effects, complex gradients or chart objects do not always have a direct static equivalent. Those elements are approximated, while text, shapes and images render faithfully.

Is my presentation uploaded anywhere?

No. The .pptx is unpacked, parsed and rendered entirely in your browser. Your slides never leave your device.

Does it work on mobile?

Yes. You can pick a .pptx from your phone's files, review the slide list and convert in any modern mobile browser.

About PPTX to PDF

Slides That Travel Well

PowerPoint files are great for presenting and awkward for everything else. Recipients may not have Office, fonts can shift, and a deck that looked right on your machine can reflow on someone else's. This tool reads the OOXML package inside a .pptx file and rebuilds each slide as a PDF page, so the result opens the same way everywhere.

After you drop in a presentation, the tool lists the slides it found so you can confirm the deck before converting. The PDF keeps the slide's own dimensions — widescreen stays widescreen, 4:3 stays 4:3 — instead of forcing everything onto A4.

What Carries Over

The converter focuses on the visual layer of the deck: layout, text and images.

One Slide Per Page

Each slide becomes exactly one PDF page, preserving the deck's order and aspect ratio.

Text and Shapes

Text boxes, fills, lines and basic shapes are drawn onto the page rather than flattened into a screenshot.

Embedded Images

Pictures inside the presentation are extracted from the package and placed back on the slide.

Local Conversion

The .pptx is unpacked and rendered in your browser, so internal decks never touch a server.

Know the Limits Before You Send

A PDF is a static document, so anything that only exists while PowerPoint is running does not survive the trip: animations, transitions, embedded videos and speaker notes are left behind. Complex effects such as 3D rotations, SmartArt or unusual font substitutions may be simplified to the closest static equivalent.

That trade-off is usually the point. For handouts, review copies, archiving or sharing with people who just need to read the slides, a faithful static rendering beats a perfect recreation of effects they were never going to see.

How It Compares

Exporting from PowerPoint is fine if you have PowerPoint. This is for everywhere else.

Private Enough for the Real Decks

The presentations people actually need to convert are rarely the public ones — they are board updates, sales decks, internal training and quarterly numbers. Sending those through an upload-and-wait service means trusting a server you cannot audit.

OxygenPDF parses the .pptx package and builds the PDF locally. Nothing is uploaded, nothing is queued, and closing the tab clears the deck from memory.
