Portable Document Format (PDF) is a file format used to present documents in a manner that is independent of the implementation of software, hardware, and operating systems. A PDF file contains a comprehensive representation of a static, structured document, encompassing its text, fonts, graphics, and essential data required for proper display.

Sometimes, when performing operations on a PDF document, it’s discovered that the file cannot be opened. This could be due to any of the following reasons:

  • Unexpected Power Loss: Frequent sudden power interruptions or other unforeseen events can lead to the abrupt shutdown of the computer. This, in turn, heightens the risk of PDF file corruption, as the system fails to properly close all open files during the unexpected shutdown.
  • Impact of a Virus: Computer viruses are harmful software created to disrupt your computer’s file system or harm stored files. If your computer is infected with such a virus, the risk of PDF file corruption increases significantly.
  • Formation of defective sectors on your data storage device: Over time, data storage devices such as your local hard drive, external hard drive, pen drive, etc., may experience the development of defective sectors. If your PDF file happens to be stored on one of these defective sectors within your storage media, it runs the risk of becoming corrupted.
  • Concerns regarding the Acrobat Reader version: Issues with your PDF application, such as sudden closures of open files or improper shutdowns, may lead to the corruption of PDF files.
  • PDF File Size: Given that PDFs aren’t designed to handle vast amounts of data like a database, having a large-sized PDF increases the likelihood of corruption.

In addition to these factors, challenges such as power outages, system issues, varying Acrobat versions, and assorted PDF errors significantly contribute to troubling the user.

  • Format error: not a PDF or corrupted.
  • File is corrupt or damaged.
  • The root object is missing or invalid.
  • File does not begin with %PDF.
