For example you can print a Word document with the PDF printer and soon you will have a PDF version of your Word document.
For creating PDFs PDF24 offers many other possibilities
The software described above is available to download and install. PDF24 also offers an Online PDF Converter where a person can convert a set of files into PDF files. Upload the file and an automatic service from pdf24.org will convert the file to a PDF. This option is very convenient if you do not have the PDF24 PDF Creator installed.
There is also an e-mail PDF converter that allows for creating multiple PDF files at once. It just needs an e-mail with all the documents attached sent to a specific email address and in a few seconds you will receive an email back with all the files converted to PDF.
