Clean PDF metadata before sharing
Remove author names, producer and creator apps, document titles, creation dates, modification dates, 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 PDF metadata remover reports only field names and presence flags, so raw metadata values stay out of the browser response and logs.

常见问题解答
Can I remove metadata from PDF online for free?
Yes. Convertr is a free online PDF metadata remover 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 PDF metadata can I clear?
The cleaner targets common PDF fields such as title, author, subject, keywords, creator, producer, creation date, modification date, 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.
上传的 PDF 是私密的吗？
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.
