How to edit metadata
- Add your file. Click the drop zone or drag a single PDF onto the page.
- Review the current details. Existing title, author, subject, and other fields load automatically.
- Edit and save. Change any field, then apply the update directly in memory.
- Download. Save the updated file straight to your device.
Why do this locally instead of online?
A document's metadata can reveal more than people expect — the real name behind a shared account, an internal project codename, a previous author's identity. This tool reads and rewrites metadata using a library running directly in your browser.
Frequently asked questions
What is PDF metadata, exactly?
Behind-the-scenes fields like title, author, and subject, stored in the file itself but not printed on the page.
Does clearing metadata make a PDF fully anonymous?
It removes these specific fields, but a PDF can carry other identifying details in its content.
Will editing metadata change how the document looks?
No — only the behind-the-scenes fields change.
Can I remove all metadata instead of editing it?
Yes — clear each field and save; empty values are stored as blank.
