How to lock PDF? For those of you who often deal with document files, you must be familiar with PDF files. PDF stands for Portable Document Format created by Adobe System Inc. We know that Adobe is one of the biggest companies that has produced many useful applications for society. One of them is Adobe Photoshop which is still the best video editing application.

Although at the beginning of the emergence of PDF is still not as popular as it is now. This is because the file is still not connected or integrated with the WWW. However, Adobe System Inc. has improved, and now PDF files are one of the most widely used files. In addition, the file size, which tends to be larger than files other than the PDF format, is also a consideration for the public to use or convert the file to PDF.

Even PDF is not only available for computers and laptops. You can open PDF format documents via your smartphone. You are coupled with the many applications available that function to read this file, such as Adobe Reader, Foxit Reader, and so on.

This convenience means that you don’t need to open your laptop to view or read PDF files. In addition, it turns out that PDF files can also be opened via a browser. Some of these browsers include Google Chrome, Mozilla Firefox, and others.

  • Maybe some people think that PDF files can only be read-only. We can not edit the contents of the text in it. This assumption is, of course, wrong. You should know that there are PDF Reader applications that provide editing features. That is, you can edit the text or the content in it.
