About this tool
Correct a document title or author field that appears in a PDF reader without editing page content.
How to use
Choose a PDF to load its document information. Edit the title, author, subject or comma-separated keywords; the result preview updates automatically. Compare with the original and download the same processed file shown in the preview.
Each field supports up to 2,000 characters. This edits document information, not page text, attachments, hidden content or XMP metadata, and is not an anonymization tool. Saving changes invalidates digital signatures. Encrypted PDFs are unsupported. File limit: 64 MiB and 2,000 pages.
Common questions
Does clearing these fields anonymize the PDF?
No. This edits document information, not XMP, attachments or hidden page content. Saving also invalidates digital signatures. Encrypted PDFs are unsupported.
Why does the heading inside my PDF stay unchanged after editing the title?
The title field belongs to the document information shown by PDF readers; it is not text drawn on a page. Check the downloaded file’s document properties. This tool does not replace visible headings, author names or other page content.
