Check PDF Properties in Adobe Acrobat or Reader
Use the built-in document properties menu in Adobe Acrobat or Reader to view the creation details.
When a document is converted to a PDF, the original source application is often recorded in the file's metadata. You can access this information directly from the PDF viewer.
Launch Adobe Acrobat or Adobe Reader and open the target PDF file.
Click on 'File' in the top menu bar and select 'Properties' from the dropdown list.
Navigate to the 'Description' tab within the Document Properties window.
Review the 'Application' and 'PDF Producer' fields to identify the original software and conversion tool used.
Check PDF Details Easily with WPS Office
WPS Office provides a comprehensive PDF tool that allows you to view document properties, edit text, and seamlessly convert PDFs back to their original Office formats.
- 1. Open PDF in WPS: Open your PDF document using WPS PDF.
- 2. Access Document Properties: Click the 'Menu' icon in the top left corner and select 'Document Properties'.
- 3. Identify Source Format: Under the 'Description' tab, check the 'Application' field to see the original format or creator software.
Frequently Asked Questions
Can I tell if a PDF was originally a Word document?
Yes. By checking the Document Properties, the 'Application' field will typically display 'Microsoft Word' if it was created and converted directly from a Word file.
What if the Application field in the PDF properties is blank?
If the Application or PDF Producer fields are blank, the metadata may have been stripped for privacy, or the software used to create the PDF did not embed this information.
Can I restore the PDF back to its original format?
While you cannot automatically revert a PDF just by checking its properties, you can use PDF conversion tools (like PDF to Word or PDF to Excel) to transform it back into an editable format based on its original layout.
How do I view PDF properties without Adobe Acrobat?
You can use alternative PDF readers like WPS PDF, or modern web browsers. In most browsers, you can open the PDF, click the three-dot menu, and select 'Document Properties' to view basic metadata.
