About This Tool
PowerPoint to PDF converts a .pptx, .ppt or .odp presentation into a PDF with one page for each slide. LibreOffice Impress, compiled to WebAssembly, opens the file inside your browser tab and exports it. Add the presentation, select Convert to PDF and download the PDF, which keeps the name of the original file.
Each page is a still copy of its slide. Animations, transitions, video and audio do not carry over, and objects that would appear one by one are all shown together. The export uses LibreOffice's default settings, which produce the slides only, so speaker notes are left out. Shapes, charts and text are drawn by LibreOffice rather than PowerPoint, which means complex SmartArt, special effects and theme fonts can look slightly different.
The engine is about 260 MB of files before compression and begins loading as soon as you open the page; after the first visit it comes from your browser's cache storage. It cannot use the fonts on your computer, so text set in a font it does not bundle is replaced and may reflow inside its box. Files over 50 MB are refused, which matters for decks with embedded video, and a conversion still running after five minutes stops with an error. There is no password prompt.
The presentation is converted in the tab and is not uploaded. A Batch PPT/PPTX to PDF panel below the converter takes several decks and converts them in turn. If a training deck is part of a training record, convert the approved version and file that PDF, so later edits to the slides do not change what was presented.
How to Use
Open the tool
The conversion engine starts loading at once and a progress panel tracks it. Allow extra time on the first visit.
Add your presentation
Drag a .pptx, .ppt or .odp file onto Upload PowerPoint File, or click to browse. The main converter takes one file at a time.
Select Convert to PDF
A progress bar runs while LibreOffice exports the slides. Cancel is available if you need to stop.
Download and check
Select Download, then scroll through the PDF to check fonts, charts and any slides with dense text.
Several decks at once
In the Batch PPT/PPTX to PDF panel, add the files, select Start batch conversion, then Download all or Download ZIP.
Use Cases
Filing a training session
Keep a fixed copy of the slides used in a GMP or safety training session alongside the attendance record.
Sending slides after a meeting
Share a steering committee or project update deck as a PDF that opens on phones and tablets without presentation software.
Uploading a conference poster or talk
Many abstract and conference systems ask for slides or posters as PDF. Convert the final deck locally before you submit it.
Printing handouts
Produce a print-ready PDF of a deck so the printed copy matches what was on screen, one slide per page.
Frequently Asked Questions
Are animations and transitions kept?
No. A PDF page is static, so each slide is exported in its finished state with every animated object visible at once. Transitions, video and sound are not included.
Are speaker notes included?
No. The converter uses LibreOffice's default PDF export, which outputs the slides only and leaves the notes out.
Will my fonts look the same?
Only if LibreOffice bundles them. The engine runs in a sandbox and cannot read fonts installed on your computer, so other fonts are replaced, and text can grow or shrink inside its box. Check slides with tight layouts.
My presentation is over 50 MB. What can I do?
The tool refuses files above 50 MB. Large decks are usually heavy because of embedded video or uncompressed photos, so remove the videos or compress the pictures in PowerPoint, save a copy and convert that.
Why does the page take so long to get ready?
It is loading LibreOffice, roughly 260 MB of files before compression, into your browser. That happens on the first visit; afterwards the engine is read from your browser's cache storage.
Is my presentation uploaded?
No. The file is read and converted inside the tab. Only the engine files are downloaded from this site.
