This program is, as its name clearly suggests, a PDF document creator. The application works with various formats, allows you to convert multiple files at the same time, and enables you to combine documents with different extensions into a single PDF.
From the main toolbar of the utility, you can select the type of conversion you wish to execute (DOCX to PDF, image to PDF, etc.). Once you complete the aforementioned step, you can choose the input files and the destination folder.
There's also an optional preference on the bottom of the main window that, once enabled, merges all input files into a single PDF.
I like the fact that you don't have to wait much for the results. Even when converting multiple documents to the PDF format, the application offered the output files within seconds.
My only concern regarding this program is that it sometimes fails to preserve the original layout of the input files. In my testing, I selected a DOCX file as input document and the resulted PDF had some page arrangement changes.
If the aforementioned flaw doesn't mean much to you, I'd say it's worth acquiring this app for your Mac. Otherwise, I'd suggest you try more capable PDF converters to get the quality results you require.
