When PDF files become corrupt, it can lead to the loss of sensitive and irreplaceable information. This often happens without warning. However, even if you experience strange behavior with your PDF, it’s still possible to fix file errors.

We'll discuss common file corruption problems with Adobe Acrobat PDF and provide possible fixes.

What To Do When PDF Files Don’t Load

If you can re-download the file, try again. File corruption can sometimes occur due to interrupted downloads. If this fails, ensure that the file extension matches the file type. You can also try updating Adobe Acrobat to rule out version incompatibility as a root cause.

Once the software has repaired your corrupted PDF document, data is stored in a new, recreated PDF file.
