    In this article, I will show you one method of checking PDF detail information without opening PDF files. The way of checking PDF basic information is through checking PDF metadata. Metadata provides additional information about a certain file, such as its author, creation data, possible copyright restrictions or the application used to create the file. The software I use here is a kind of cloud based application named VeryPDF PDF Metadata Manager Cloud API, which allows you Extract or Insert Title, Author, Subject, Keywords, Creator, Producer, Created Date, Modified Date from/to PDF files. Please check more information of this software on homepage, in the following part, let us check how to use this software.

Step 1. Know the principle of how PDF Metadata Manager Cloud API works.

Then choose a method of paying for this software, you can pay for it per month or per year then you can use all the VeryPDF cloud applications the whole month or year. Once you finish paying, the code will be sent to your email box at once.

Simply make sure the website connection is good and open any browser then copy the following URL to browser, you can check PDF metadata. Here is an URL for your reference:
