On a Apple computer, the “Print” function of the “Preview” app includes the choice for printing the open file to PDF. This works for converting various picture formats to PDF. In fact, any open printable file can be printed as a PDF. If your objective is to make a PDF into a searchable PDF, Word To Pdf Conversion works. There are some “free” software listings on the Internet, but I can’t suggest one or another. On a Apple computer, if you just want to merge two or more PDF files, click theft-most icon above the main PDF window. There’s dropdown with several choices. The second is to open “thumbnails”. Click it; you get thumbnails of every slide in your PDF file. Do this with both of the files you want to merge. Drag thumbnails from one file to the other - in the order you choose. You now have the merged file. (This is probably identical in the Windows operating system.) HTH
You are trying to make mistakes? What should I be sure of before I edit and turn in the final PDF? Be sure you have your title, first paragraph, footnotes, author list, and bibliography on the first page and that the page has an appropriate chapter headings! After turning in your final PDF for editing, should I scan the document and copy it to my computer, print it, or save it to the cloud? No scan, print or save. How do I print my document? Print using a document printer. Can you send me the PDF? You can not! It would be a breach of copyright, as you are copying my work (which, if it was not protected by copyright, is still yours!). Can you send me the copy of my original file I uploaded to a cloud-based service? You can not! A “cloud-based service” is a service.
