Fix Acrobat Reader Cannot Open PDF: Unsupported or Damaged File
Question details
The user is unable to open a PDF in Acrobat Reader DC and receives an error stating the file type is unsupported or the file is damaged, often after using Microsoft Print to PDF.
- Product
- Adobe Acrobat Reader DC
- Device & OS
- not provided
- Scenario
- Attempting to open a recently saved or generated PDF file, particularly after filling out an interactive form and saving it via a virtual printer.
- Observed behavior
- Acrobat Reader DC displays an error message indicating the file is damaged or in an unsupported format, preventing the user from viewing their saved work.
Check your PDF's file properties before proceeding. If the file size is listed as 0 bytes, the document is empty and unfortunately cannot be recovered; you will need to recreate the file.
Verify File Integrity and Try an Alternative PDF Viewer
Determine whether the file is permanently corrupted or if the issue is strictly isolated to Adobe Acrobat Reader.
Sometimes Acrobat Reader flags a file as damaged due to minor syntax errors in the PDF generation process, even if the content is intact. Opening the file in a different program can bypass this strict validation.
Right-click the problematic PDF file and select 'Properties' to verify the file size. If it is larger than 0 bytes, proceed to the next step.
Right-click the PDF, hover over 'Open with', and select an alternative viewer such as Google Chrome, Microsoft Edge, or WPS Office.
If the file opens successfully in the alternative viewer, use that program's 'Save As' or 'Download' feature to create a fresh, uncorrupted copy of the PDF.
Use Save As Instead of Print to PDF
Prevent future file corruption when saving filled PDF forms by avoiding virtual printing methods.
Reinstall the Microsoft Print to PDF Driver
Fix recurring corruption issues caused by a malfunctioning Microsoft Print to PDF virtual printer.
Open, Fill, and Save PDFs Safely with WPS Office
Avoid file corruption errors and complex virtual printer issues. WPS Office provides native, reliable PDF reading and form-filling capabilities directly out of the box.
- 1. Open the PDF: Launch WPS Office and open your blank or existing PDF document directly within the application.
- 2. Fill the form: Click on the interactive form fields to easily type your information using the built-in PDF tools.
- 3. Save securely: Click 'Menu' and select 'Save As' to preserve your data securely without relying on error-prone Print to PDF methods.
Frequently Asked Questions
Why does Microsoft Print to PDF create a 0-byte file?
A 0-byte file occurs when the system creates a placeholder file in the destination folder but fails to write the actual document data. This is typically caused by restricted folder permissions, special characters in the file name, or a stalled background printing spooler.
Can I recover my data from a 0-byte PDF file?
Unfortunately, no. A 0-byte file contains absolutely no data. Since the information was never successfully saved to your drive, you will need to start over and recreate the document.
Why does Acrobat say my PDF is damaged only after I fill out a form?
This happens when you use 'Print to PDF' on an interactive form rather than saving it natively. Virtual printers flatten the document, which can misinterpret form fields and break the PDF's internal code. Always use 'File > Save As' to save filled forms.
