PDF Corrupted? How Can You Easily Repair Your Corrupted File


PDF is the most commonly used document format. It is used in offices, educational institutions, and software houses, and every other person uses it for their work. PDF has become so popular because it is a secure document format; you cannot make changes to it directly without an editor. If someone does some editing, you can use the PDF editor’s Compare PDF feature to compare original and edited PDF files. 

PDF files do not change when opened on another device, they remain consistent, and these files are not, so memory taking. Finding that your PDF file is corrupted is something nobody wants to face. A good file fixer can solve your issue, and this article has one for you.

Part 1: Proficient Causes of Why Your PDF Corrupts?

What are the reasons that cause someone to use a PDF repair tool? Following are some of the reasons that can cause PDF file corruption:

1. Virus Attack

If your computer has caught a virus, then it is very much possible that the files stored in your computer can be affected by the malware. The virus can also affect the PDF even if you have stored it on a USB Drive. When the USB is connected to the computer, it comes in contact with the malware, and thus the files in your USB are also affected by it. The virus can cause many files to stop working and become corrupt, and your PDF file could be one of them. 

2. Download Error

Download errors often occur, and they are mostly because of unstable or limited internet connection. If your internet is giving you a hard time and the speed is slow, then the files that you have downloaded can show errors and become corrupted. Another reason your file can get corrupted while downloading is interference. If the PDF file is interrupted when it’s being downloaded, then it will fail to open, and the file gets corrupted.

3. Using the Wrong PDF File Reader 

Sometimes a change even as small as using a different incompatible PDF file reader can make a huge difference. Opening your PDF with apps or software that are not compatible with it can cause errors. If you use the wrong PDF file reader, it will not open your file but instead cause an error and corrupt your file. A supported file reader should always open a PDF file; otherwise, you will not be able to open your document and read it.

4. Hard Drive Failure 

If your hard drive is even partially faulty, it can cause corruption in the files stored in it. Sometimes the hard drives seem to be working fine, but they can damage your files. The hard drive only stops working when it is completely failed, but this doesn’t mean it cannot corrupt your PDF. Many system errors can cause the hard drive to stop working, and the files stored in it become corrupted.

5. Sudden Shutdown

When saving your PDF file, if your computer suddenly turns off, it can cause the file to become corrupted. The computer can suddenly shut down because of a power supply failure or if the light goes out suddenly. However, power failure is not the only reason; sometimes, the system can unexpectedly shut down. If you are downloading or editing your PDF file when your laptop or computer shuts down, then it can cause errors in your PDF file.
