Here’s how to save a text file as a PDF file:
1. Open your text or word processing document, or create a new one.
2. From the File menu, select Print. The Print window will appear. Click the PDF button, and then select Save As PDF.Note that there are plenty of other options to explore under the PDF button. We won’t be discussing those in this tutorial, but we’re quite fond of the Encrypt PDF option. That will password-protect your PDF file.
3. Select a location to save your PDF file.
4. That’s it! You now have a PDF file that looks exactly like your text file. You can compress this file and email it to someone else, or you could just keep it as a backup. Either way, you’re good to go!
