Although Adobe Acrobat is the original software for creating PDFs, you can use Microsoft Office Word 2010 to create a document including text and images and save it as a PDF file.

You can easily generate Google Sheets PDF links via Google Drive to share them as PDF files. There's no need to convert them manually. See the instructions here.

If you select multiple files and then Ctrl+click on the selection, you can pick Quick Actions and Create PDF to do just that (most common file types are supported).
