How to Repair Damaged PDF Files for Dropbox Users

Dropbox users face the daily risk of losing crucial information and valuable memories while operating and sharing their files via the cloud-based service. In addition, data corruption is becoming a real challenge for users who do not know how to get their damaged files repaired quickly and painlessly in just a few clicks using https://pdf.recoverytoolbox.com/online/ – for any device and operating system (Android, iOS, macOS, Windows) and https://pdf.recoverytoolbox.com/ – for Windows only.

What May Cause Corruption on My PDF in Dropbox?

In most cases, it is rather challenging to determine why the files containing crucial data become damaged.

It could be due to various reasons ranging from:

Error syncing data in a folder on a local device and Dropbox storage

The error occurs due to incorrect synchronization of PDF files between a computer, tablet, or phone and the Dropbox service due to connection failures, time settings failures, or incorrect checksum verification. As a result, only damaged PDF files remain on the Dropbox service and the user’s device. Unfortunately, it is tough to track when and why this happened.

Autosave mode

Autosave is a feature, which protects data in case of a PDF reader program or system crash, power outage, or sudden termination of the program. It only makes a temporary safety cache file while a file is open. As soon as it is closed under normal circumstances, the Autosave temporary file is deleted, but sometimes files are not saved correctly due to the 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. For example, your Dropbox PDF file would be damaged and unopenable if the missing data were a file component. So make sure not to have a faulty disk before operating PDFs. 

The encoding used by e-mail service providers

E-mail service providers occasionally encrypt large files, including PDFs. As a result, sending and receiving e-mails will happen more quickly. 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 x 297 with the 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. To reduce these dangers, ensure you have a steady connection before downloading any files.

Five Best Ways to Repair Damaged/Corrupted PDFs in Dropbox

  • Try alternative PDF Reader applications: If Adobe Reader fails to open the file, it is quite possible that the application you are using to access the file is not working. Therefore, we advise you to try alternative PDF reader applications like Foxit Reader.
  • Update Adobe Reader: Make sure that your Reader is up-to-date. If an update is available, install it and check the installation files.

  • Restore a previous file version: Windows has a built-in feature to back up different file versions in case the latest version of the file gets corrupted or damaged.
  • Use the free online PDF repair tool: There are many online PDF repair tools that you can go for to repair your files. However, the file size is usually limited, and the file version is not to be changed. Take a look at PDF2GO, for instance.
