How we handle your data

PowerPoint to PDF

Convert a PPTX technical presentation into a landscape PDF record, keeping slide layout, labels and figures in position. Your file stays in your browser.

Choose your document

Choose a PPTX file and convert it to PDF. The first conversion prepares the local Office engine and may take a moment; the next file on this page is faster.

Local limit: 10 MiB per document

Choose a document, then convert it to PDF.

Processing happens on this device. Keep this tab open until your PDF is ready.

What to expect

Text, images and page layout are converted together. Fonts and complex formatting may differ from your Office editor; check your PDF before sharing.

Slides are exported as static PDF pages. Animations, video and transitions do not remain interactive.

Large documents may exceed your device’s available memory. If conversion fails, try a smaller document or another device.

Help with conversion

The converter does not start

Check your connection while the converter prepares itself, then retry. This converter needs a modern browser and sufficient memory.

My document could not be converted

Open the document in your editor and save a new PPTX copy. Password-protected, damaged or unsupported files may fail. The input limit is 10 MiB and the PDF output limit is 20 MiB.

Processing takes too long

Preparing the converter stops after two minutes; conversion stops after one minute. You can cancel during processing and restart with a smaller document.

A practical guide

Archive the presentation as landscape pages.

  1. Select the PPTX source presentation for the record.
  2. Convert it; each slide becomes one landscape PDF page.
  3. Verify labels, units and figure placement against the source slide.

Try this example

Convert a seven-slide PPTX review deck containing two diagram slides; confirm slide 3's diagram labels remain legible and in position on its landscape page.

Before you start: Only static slide content is preserved; speaker notes and any embedded animation sequence are not part of the PDF record.
