Easy Fixes to The File is Damaged and Could Not Be Repaired

Fix 1. Re-download the PDF File

If you got the PDF from a website or email, the file may not have downloaded properly. You can delete the damaged file and re-download it from the original source. Before opening the PDF file, ensure the download has been completed.

 

Fix 2. Try a Different PDF Reader

Sometimes, Adobe Reader or Acrobat struggles with minor corruptions that other readers tolerate. Try opening the file with Foxit Reader, SumatraPDF, Nitro Reader, or even Google Chrome (drag and drop the PDF into the browser).

If the file opens elsewhere, you can save/export it again as a new PDF.

 

Fix 3. Update or Reinstall Your PDF Reader

Sometimes the error isn't entirely the file’s fault — your reader might be outdated.

You can update Adobe Acrobat Reader (or your current PDF app) to the latest version: Hit the Menu button to get all options, then click on Help and choose Check for updates. After that, if there is new update, you can download and install it.

If updating fails, uninstall and reinstall the reader completely. Newer versions are better at handling minor file corruptions.

 

Fix 4. Change Security Settings in Adobe

There is a setting called Enhanced Security in Adobe that ensures PDF files remain uncorrupted and free from harmful data from untrusted sources. To get rid of the error message “There was an error opening this document. The file is damaged and could not be repaired”, you can try to disable this setting.

Step 1: Open Adobe Acrobat Reader and click Menu> Preference.

Step 2: Click Security (Enhanced) on the left menu. Then go to the Enhanced Security section and uncheck the Enable Enhanced Security option.

Step 3: Hit the OK button to apply the change. Finally, re-open Adobe Acrobat Reader and open the PDF document again.
