But what if you are looking at an online document and you need to save it as a PDF? You can create a PDF from a hard copy document by scanning it and saving the scan as a PDF. If you need to send something with any kind of legality, you’ll probably be asked to send it as a PDF. Since then, PDFs have become a standard for sending official documents. The idea was that the document was an exact, unchangeable copy of the original (while some PDFs can now be edited, you can create a PDF that cannot). In case you’re not familiar with the background of that format, PDF stands for portable document format and was created by Adobe in the early 1990s to allow people and organizations to create exact digital versions of paper documents. Now that so many people are working remotely, it’s become more accepted than ever for official documents to be sent digitally - and most are sent as PDFs.
