Strip metadata from a PDF
Share a PDF without revealing who created it, with which app, when it was edited or which files and scripts it contains.
What it does
The tool removes document information (title, author, subject, creator, producer, dates and identifier), XMP blocks, private application data, attachments, JavaScript, XFA forms and automatic actions.
It can also strip comment authorship without deleting the annotations. Deep mode copies the pages into a new document and also removes links, bookmarks, forms and structure: it is more aggressive and may change how the PDF behaves.
How to use it
- Open Remove PDF metadata.
- Add one or several PDFs.
- Select the blocks you want to clean. All common metadata is selected by default.
- Enable deep mode only if you also need to remove annotations, forms or structure.
- Press “Clean metadata” and download the files.

What metadata a PDF carries and why removing it matters
A PDF can store who created it, with which program, the creation and modification dates, the title, subject, keywords and an XMP block with workflow data. In a shared document that is often enough to identify a person or a company even when the text says nothing.
The cleaner removes the information dictionary, the document identifier, the XMP metadata, thumbnails and automatic actions, while keeping the visible content. Use it before publishing a PDF on a website or sending it to a client: the file looks the same, but it stops telling where it came from.
Frequently asked questions
Which metadata does it remove?
Author, title, subject, keywords, creator, producer, dates, unique identifier, XMP, PieceInfo, attachments, JavaScript, XFA and automatic actions.
Is the PDF content deleted?
No. Text and images are preserved. Deep mode copies the pages and may lose links, bookmarks, forms and annotations.
Does it work with digital signatures?
No. A digital signature depends on the exact bytes of the document; rewriting it invalidates the signature. If you need to keep the signature, do not use this tool.
Can I clean several files at once?
Yes, up to 30 PDFs per batch, with a maximum of 300 MB per file and 500 MB in total.
