Frequently Asked Questions

PDF metadata affects how your document is indexed by search engines, labeled in document management systems, and displayed in PDF readers. Proper metadata improves document discoverability, helps with compliance, and removes personally identifiable information before sharing.

No. Metadata is stored separately from the visible page content. Editing metadata only changes the embedded descriptive information — the text, images, and layout of the PDF are completely preserved.

Yes. Simply clear any field you want to remove. After saving, that metadata property will be absent from the PDF. This is useful for removing the Author field before publicly sharing a document.

PDF metadata keywords are read by some search engines (including Google) when indexing PDFs. Good title and keyword metadata can improve the discoverability of publicly available PDFs in search results.

If the PDF requires a user password to open, you need to know it to process the file. If it only has an owner (restriction) password, metadata editing should work normally.
