Share documents with fewer details

Remove author names, editor tools, document titles, timestamps, and XMP packets before sending PDFs outside your team.

Preserve page output

Clean metadata without compressing the PDF, lowering image quality, changing page dimensions, or rasterizing vector content.

Check before cleaning

The analysis step reports only field names and presence flags, so raw metadata values stay out of the browser response and logs.

  2. 2

    Review the safe field-name summary if metadata is detected.

  3. 3

    Remove common PDF metadata without compressing or rasterizing pages.

  4. 4

Frequently asked questions

Is this PDF metadata remover free?

Yes. Convertr removes common PDF metadata for free, with no account, no watermark, and no software installation.

Does metadata removal change PDF quality?

No. This tool clears writable metadata and rewrites the PDF structure with qpdf. It does not rasterize pages, downsample images, or reduce resolution.

What metadata can be removed?

The cleaner targets common PDF fields such as title, author, subject, keywords, creator, producer, creation and modification timestamps, document IDs, and XMP metadata packets where safely writable.

Does this guarantee forensic sanitization?

No. Some metadata can be hidden in embedded files, signed revisions, annotations, custom objects, or application-specific structures. Use this as a common metadata cleanup tool, not a forensic redaction system.

What happens to signed PDFs?

Changing document metadata can invalidate digital signatures. Keep the original signed file if you need to preserve signature validity.

Are uploaded PDFs private?

Files are processed in short-lived temporary storage and automatically deleted after processing. Convertr does not log filenames, PDF content, or raw metadata values for this tool.
