Got some content that you want to allow others to see, but not edit or print?
FlexiPDF Professional 2022 supports two levels of document password protection and five levels of documents encryption. A password can be used to protect the document when it is opened, preventing unauthorized access. Another, separately defined password can control any changes made to the document, preventing unauthorized changes. You can distribute a PDF with confidence, knowing that unauthorized access and unauthorized changes will not occur without your consent.
With FlexiPDF Professional 2022, documents can be secured with various user permissions, so when you publish documents to the web you can be assured that anyone opening the document will not be able to extract information from.
