Frequently asked questions
Why does PDF metadata matter?
Titles and keywords help document management systems, operating systems, and search engines properly index your file.
Does editing metadata alter the visible page content?
No. Only the hidden document properties are updated; the actual text and images on the pages remain completely untouched.
Can I clear an existing metadata field completely?
Yes. Simply delete the text in the field so it is empty, and save the file to wipe that specific property.
