Part 1. Potential Causes Behind a Corrupted PDF File on Windows or MacBook

Before beginning the process of fixing damaged PDF files, it is important to understand some of the possible reasons that may have led to corruption. In this section, we've identified the most common reasons for file corruption in Windows and Mac systems:

1. File Download May Be Incomplete: If there is a break while a PDF file is downloading and the download is incomplete, it could also render the PDF corrupt. A damaging source here is the unstable internet, which may occur during the download process.
2. Virus Attacks: Malicious software can damage a system that can corrupt PDF files. These viruses or malware may alter the file's content, making it unreadable or causing it to fail when opened, driving the need to repair damaged PDFs.
3. File Transfer Problems: Network issues or file system inconsistencies can also cause corruption during the transfer of PDF files between devices or over the internet. Improperly closing the transfer or issues with file compression can also damage the file.
4. Hardware Failures: Issues with your hard drive or storage devices, such as bad sectors or disk corruption, can lead to PDF file damage. A failing hard drive may not properly save or retrieve files, which results in corruption.
5. Software Crashes: Unexpected crashes or errors in PDF software, such as Adobe Acrobat or Preview on Mac, can corrupt files. This typically happens if the program closes improperly or loses connection with the file during saving.
