Posts like these can be found on just about every tech-related discussion board online, and they illustrate that PDF recovery is a major issue that’s affecting countless users every single day. 

Can PDF Files Be Recovered?

Yes, it’s possible to recover deleted or unsaved PDF files, but only if certain conditions are met:

  • The deleted PDF files have yet not been overwritten. 
  • The unsaved PDF files are present among temporary files. 
  • The lost PDF files were not stored on a TRIM-enabled solid-state drive (SSD).  

If you meet these three conditions, you can proceed to the next chapter, which describes several different PDF recovery methods. Regardless of which method you use to get back your PDF files, we highly recommend you don’t delay the recovery process since time isn’t on your side when it comes to data recovery.

4. How to Repair a Corrupted PDF File

The PDF file format is known for its ability to preserve content and formatting across devices, but it’s not immune to corruption. There are many reasons why PDF files may become corrupted, including: 

  • Failed downloads or transfers: When downloading PDF files from the internet or transferring them between devices, it’s important for the download or transfer process to finish completely otherwise the files may become corrupted. 
  • Storage device failure: Unfortunately, no storage device offers perfect reliability. Even in perfect conditions, hard drives, USB flash drives, memory cards, and all other storage devices occasionally fail—sometimes completely and sometimes partially. 
  • Improper shutdown: A sudden, unexpected shutdown of a computer can interrupt important data transfer processes and cause PDF corruption or even lead to a PDF file disappearing from the storage device.

What Is an Expired PDF File?

An expired PDF file is impossible to open because the creator of the file limited access to it until a fixed date and time. Such PDF files are typically created to prevent access to sensitive information, and they are common in the business sector. Because the PDF file format doesn’t natively support expiration dates, a third-party Digital Rights Management (DRM) is required to create PDF files that automatically expire.
