Have a damaged or corrupt PDF? Try these programs or websites

These PDF files are characterized by their good integrity, however, they are not exempt from the fact that when they are downloaded or received, they are damaged or corrupted, which ends up making it impossible for us to open or read them.

Reasons why a PDF can get corrupted

PDF files are not perfect and any other file can be in situations where they can be damaged or corrupted, preventing us from using them. This is something that can happen during use and can be due to different factors, such as:

  • Problems saving a file.
  • Hard drive failure corrupting some bytes of the document.
  • Sudden closing of the program with the PDF open.
  • Failure to send it through the Internet that prevents its correct decoding.
  • Crash or shutdown of the operating system.
  • Attacks caused by a virus or malware that directly affects the document.
  • Crash when editing with a text editor not compatible with this format.

Luckily there are different types of tools, both to be used from our computer and to be used online from our browser, which will allow us to repair these damaged files, to access the new content of the document again. These applications must be able to recover the structure of damaged files so that we can reread them as a new document.
