How to Open Broken PDF Files

Just like every other document format in the digital world, PDF documents are exposed to the risk of data corruption, loss, and damage while being shared or viewed. Unfortunately, since Adobe launched PDFs in the early 1990s, there have been complaints about the inefficiency of the recovery solutions for corrupt PDF documents they have offered.

However, with the Recovery Toolbox for PDF and its PDF file repair service and software, users no longer have to worry about being unable to open broken PDF files. They can painlessly and effortlessly perform their recovery tasks online on any device (phones, tablets, and computers) and operating system (macOS, iOS, Android, Windows) in just a few clicks or with Recovery Toolbox for PDF offline (for Windows only).

Unlike Microsoft, which has provided practical solutions to the problem of data corruption, Adobe suggests unworkable solutions to this problem. These solutions include an Adobe Reader update, opening an Adobe PDF document in Illustrator, or manually extracting text from a PDF file with NotePad – which may leave out the image, audio, and video files. Going through the Adobe Help & Support website doesn’t even help, and no matter how long you spend searching, here is what you will find:

What may Cause Corruption in my PDF Documents?

Determining the causes of the damage to your PDF document can be a real challenge. However, here are some of the most common reasons why PDF documents become corrupt:

Data Synchronization Errors

Errors may occur when syncing the data in your Adobe cloud folder on a local device. These errors could result from connection failures, wrong time settings, or incorrect checksum verification during synchronization between a device (computers, tablets, phones) and the cloud service.

Autosave Mode

The autosave mode is a feature that protects data changes in case the PDF program closes, the device crashes, or there is a power outage. Autosave only makes a temporary safety cache file while a file is open. This means that once the program is closed normally, the temporary autosave file is deleted. Sometimes, the autosave mode may malfunction, preventing files from being saved correctly.

Opening the Same Document with Different Software

Every software used to open and view a PDF document performs a few little adjustments to make it fit the software’s user interface. Therefore, opening the same document using several software applications may cause significant changes and file corruption.

Hard Disk Problems

A major reason for file corruption is faulty disks. Something as little as a slight drive crash could result in some data getting lost or damaged.

Encoding Used by Email Service Providers

It is not uncommon for email service providers to encrypt large PDF documents. Because these files are not decoded once they reach the receiving end, they may become corrupt. Due to this, it is recommended that large PDF documents should be zipped before they are sent by email to prevent corruption.

Mixed Page Orientation

A saved PDF document may have its page orientation hidden in its depth. For example, PDF files are usually viewed in portrait orientation. However, if the documents are in landscape orientation, this conflict in orientation may ruin the file when saving it.

Interrupted Power Supply and Internet connection

Errors could arise from a continuous interruption of power and internet connection when downloading PDF documents.
