What may cause corruption in my PDF?

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

It is often difficult to understand why crucial data-containing files become damaged. 

There are many reasons why this could be, including:

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

The error often pops up when PDF files stored on a device and in the cloud fail to match up due to connection trouble, time discrepancies, or issues with checksum verification.

Autosave mode

Autosave is a feature that creates a backup of your work in case the PDF program crashes, there’s a power outage, or the program is closed suddenly. Autosave only kicks in when the file is open; as soon as you close it normally, the autosaved temporary file will be deleted. However, sometimes files aren’t correctly saved because autosave isn’t functioning properly.

Opening the same file with different software 

Every PDF file you open is adjusted to fit the software application’s user interface. If you do this continuously with different applications, it significantly changes the file and may cause corruption.

Hard Disk problems

Faulty hard disks can cause major data loss or corruption. Even a small crash can result in lost data. 

The encoding used by e-mail service providers

If you’re having trouble sending large PDF files via email, try zipping them first. Service providers sometimes encrypt these types of files automatically, but they aren’t decoded on the receiving end, which makes them look like they’ve failed to upload properly.

The mixed page orientation in a saved file

Deep in a PDF file, its page orientation may be hidden. For example, when opened, the PDF appears as 210 mm x 297 mm with a portrait orientation. However, the file’s Orientation is set to landscape elsewhere. This mixed page orientation can ruin the file if you are not careful when saving.

Unstable power supply and an unreliable internet connection

Many things could go wrong when downloading a PDF file—for example, an unstable internet connection or an interrupted download.
