SmallPDF
SmallPDF is one of the best online services for editing, converting and creating PDF documents: it supports not only PowerPoint presentations, but also Word documents, Excel sheets, JPG images and other file types . It's completely free, requires no registration, and works with any browser. Its only limitation is that it allows you to treat only one file at a time, for the rest we can say that it is flawless.
To use it, connect to its home page and drag the PowerPoint presentation to be transformed into PDF in the browser window. Wait a few moments for the file to be uploaded online and processed and start the download on your PC by pressing the button Download the file. Easier than that?
iLovePDF
iLovePDF is a very valid alternative to SmallPDF Its free basic plan, without registration, allows you to convert only one file at a time and has an upload limit of 200MB; the paid one, which costs 3,99 euros per month, instead allows you to process up to 3 files at a time and raises the upload limit to 300MB in total. Let's see how it works.

CloudConvert
If you want to convert multiple presentations at a time, I highly recommend you try CloudConvert.

CloudConvert also allows you to merge the content of two or more presentations into the same PDF file. Just expand the drop down menu merge all into one (bottom right), select the item pdf from the latter and press the button Start conversion.
LibreOffice
If you need to convert particularly heavy presentations or, much more simply, prefer to rely on offline solutions, try LibreOffice. You should know by now - this is an excellent free productivity suite that's compatible with Windows, Mac OS X, and Linux.
LibreOffice can be used to create, edit and export to PDF any typical Microsoft Office file format: from PowerPoint PPT and PPTX presentations to Word DOC and DOCX documents through to Excel XLS and XLSX spreadsheets.

I use a Mac? Then know that after downloading LibreOffice - the procedure to follow is the same as just seen together for Windows - you must also get the language pack to translate it into cittàn (which on Windows is not needed as it is included in the basic installation package).
Then go back to the suite's website and click on the button Translated user interface. When the download is complete, open the dmg package that contains LibreOffice and copy the suite icon into the folder Applications OS X.
