Drop a PDF to see the hidden Title, Author, Creator software, and date fields — then download a clean copy with both the Info dictionary and the XMP metadata stream removed. The file never leaves your browser.
| Field | Value |
|---|
All fields above are emptied in the cleaned copy. XMP packet removed.
Page content is unchanged. Only metadata is removed.
| Layer | Removed? |

| Document Info dictionary (Title, Author, Subject, Keywords, Creator, Producer, CreationDate, ModDate) | ✅ |
| XMP metadata stream (Acrobat's File → Properties → Description data) | ✅ |
| Page content (text, images, fonts) | kept as-is |
| Annotations & form fields | kept as-is |
| Embedded JavaScript | kept — use Acrobat Sanitize or qpdf to remove |
| Embedded file attachments | kept — use Acrobat Sanitize or qpdf to remove |
Why does my PDF have author info I never typed?
Word, Acrobat, Pages, LaTeX engines, and many other authoring tools auto-fill the Author field from your OS username at install time. It's easy to forget about.
Is my data uploaded?
No. Parsing and rewriting happen in your browser via pdf-lib loaded from a CDN.
Does the page count or layout change?
No. Pages are preserved byte-for-byte where possible; only the metadata dictionary and XMP packet are rewritten.
