Will my exact font show up in the PDF?

If it’s installed on the conversion server, yes. If not, a substitute font is used, which can shift text position and wrapping.

Can I include a video in my presentation and have it play in the PDF?

No — PDF as a format has no video/audio playback, so embedded media never plays back regardless of which tool converts the file.

How do I keep my file size under the 35 MB limit?

Compress embedded images in Impress before exporting (Image > Compress), and avoid embedding unnecessarily high-resolution photos or video thumbnails.

Why did my conversion fail with a timeout?

Very large or complex presentations can take longer than the conversion time limit allows. Compress images or split an unusually large deck into smaller files.

Do complex custom shapes always convert perfectly?

Most standard shapes and layouts convert cleanly. Highly custom shape geometry or deep master-slide inheritance chains are the most likely place to see a small visual difference from the original.

Preparing Slide Decks for PDF Export

ODP to PDF renders your presentation using real, server-side LibreOffice Impress, which resolves fonts, embedded media, and layout exactly as Impress itself would. A few things about how a presentation is built affect how closely the resulting PDF matches what you see while editing.

Fonts

The server has a set of freely available fonts installed, including common metric-compatible substitutes for widely used commercial fonts. If your deck uses a font that genuinely isn’t available, LibreOffice substitutes a fallback — which can shift text position and line wrapping. Sticking to common, widely available fonts gives the most predictable output.

Embedded media

A PDF has no video or audio playback, regardless of which converter produces it — embedded video or audio in a slide cannot come through as playable media. Only static content (images, text, shapes) transfers into the PDF.

Image size and file size

Large, uncompressed images embedded in a deck push the whole file toward the 35 MB upload limit. Compressing images in Impress (Image > Compress) before exporting keeps the file well under the cap and speeds up conversion.

Layout pitfalls most likely to shift

Complex master-slide inheritance and unusual custom shapes are the most likely source of any visible difference between the edited deck and the exported PDF — simpler slide layouts built from standard placeholders convert most predictably.
