1. Common Reasons for PDF File Corruption

PDF (Portable Document Format) is probably the most popular document format because it is supported by all operating systems, and it is more secure. PDF documents are difficult to change, and they also can be protected with a password and watermarks.

However, PDF files sometimes become corrupted, and when you try to open such an Adobe Acrobat/Adobe Reader document, you might encounter various error messages, such as the following:

  1. PDF File not readable with your software
  2. Root object is invalid or missing
  3. File is damaged or corrupt
  4. There was an error opening this document
  5. There was an error processing this page
  6. It contains info not understood by the viewer
  7. Format error - Not a PDF File or Corrupted

Most often, such errors can be attributed to software malfunction (including browsers, mail programs, operating system, antivirus software or firewall).
