What may cause corruption in my PDF?

It is rather challenging to determine why files containing crucial data become damaged.

It could be due to various  reasons, including but not limited to:

  • Error syncing data in your Adobe cloud folder on a local device

The error occurs due to incorrect synchronization of PDF files between a computer, tablet, or phone and the cloud service due to connection failures, time settings failures, or incorrect checksum verification.

  • Autosave mode

Autosave is a feature that protects data in the event of a PDF reader program or system crash, power outage, or sudden termination of the program. Autosave only makes a temporary safety cache file while a file is open. Under normal circumstances, as soon as it is closed, the Autosave temporary file is deleted, but sometimes files are not saved correctly due to an autosave mode malfunction.

  • Opening the same file with different software 

Every software you use to open a PDF file performs a few minimal adjustments so that the file will fit the software’s user interface. However, if you continuously open the same file with different applications, it may eventually undergo significant changes and become corrupted.

  • Hard Disk problems

Faulty hard disks cause a major significance to loss of files or the way they get corrupted. A slight crash causes some data to be inadvertently lost.

  • The encoding used by e-mail service providers

E-mail service providers occasionally encrypt large files, including PDFs. However, they are not decoded on the receiving end, making them appear corrupt. Sending large PDF files zipped is recommended to prevent such a failure.

  • The mixed page orientation in a saved file

a PDF file may have its page orientation hidden somewhere in its depths. For example, when opened, the PDF is viewed as 210 mm x 297 mm in portrait orientation. But somewhere in the file, the orientation is landscape. The mixed page orientation may ruin the file while saving.

  • Unstable power supply and an unreliable internet connection

Many errors could arise when downloading a PDF file. An unreliable internet connection is one of these mistakes. It might also be the result of a concurrently occurring download being interrupted.
