How to edit PDF metadata
- Select Choose file or drop your PDF on the box. The current values appear in the fields.
- Change the Title, Author, Subject, Keywords or Creator. Clear a field to remove just that entry.
- Or tick Remove all metadata to wipe everything.
- Select Save metadata, then Download. The new file ends in
-metadata, or-cleanafter a full wipe.
What metadata does
Every PDF carries a small information record. Readers show the title in the window or tab, search tools use author and keywords, and libraries and document systems sort by them. Many programs fill them in automatically: a word processor writes your user name as the author, and a scanner writes its own name as the creator. Anyone who opens the file’s properties can see this.
A good title helps people and search engines. Browsers show the title in the tab instead of the file name, and screen readers announce it. That makes it worth fixing when a file is titled “Untitled” or “Document1.docx”.
Remove all metadata
For privacy, Remove all metadata deletes the information record entirely, including creation and modification dates and the producer. It also removes the XMP packet, a second hidden copy of the same details written by some programs. Pages, fonts, images, links and bookmarks are not touched. Combine this with Remove EXIF data for pictures you plan to put in the file.
Note that metadata is not the only place where names can appear. Comments, form fields and the visible text may still contain them, so check the pages too.
Tips
- Use keywords separated by commas, like
invoice, 2026, acme. - Edit metadata last, after merging, rotating or compressing, because some tools write their own details.
- See page sizes and encryption with PDF page counter.
- Lock the final file with Protect PDF, or shrink it with Compress PDF.
The file is rewritten on your device with pdf-lib. Your document is never uploaded.
