Many websites offer free PDF text editors that allow you to do some PDF editing online. PDF files often contain sensitive and confidential information, so it’s essential that any editor you use is able to protect your PDF data. One of the best ways to ensure security and privacy is to choose an offline PDF editor. All of the editing and processing in PDF Extra takes place on your own computer, rather than in the cloud, so you can be confident that your data is safe. Another advantage of PDF Extra and offline editors is that you don’t need an Internet connection to do your job. Most online PDF editors allow basic changes in the document and are not as feature-rich as PDF Extra and offline PDF editors in general.
