PDF metadata remover / editor

Wipe the hidden author, software and date metadata from a PDF before sharing it, or set your own. Everything happens in your browser.

How PDF metadata remover / editor works

View, edit, or remove a PDF's document-info metadata, author, title, subject, keywords, creator, and producer fields. pdf-lib reads and rewrites only the standard metadata dictionary; no content, images, or embedded fonts are altered.

Note: this tool targets the document-info fields it can access. Some PDFs also embed XMP metadata streams; where possible, those are cleared too, but deeply custom XMP schemas may not be fully removed, so treat it as common privacy clean-up rather than a forensic sanitiser.

Frequently asked questions

Are my files uploaded to a server?

No. Your PDF is parsed and rewritten by pdf-lib in your browser tab, the document is loaded into memory on your own device, the document-info dictionary (and, where present, the XMP stream) is edited there, and the new PDF is serialised in memory and offered as a local download. Nothing reaches Sunasty or any third party. Open your browser's DevTools, go to the Network tab and watch: no request carries your file.

Which metadata fields can be edited or removed?

Standard document-info fields: Title, Author, Subject, Keywords, Creator, and Producer. The tool clears or overwrites these fields locally; it does not modify page content or embedded resources.

Does the tool remove all hidden tracking data from the PDF?

It removes the standard document-info metadata fields and attempts to clear XMP streams. However, some PDFs contain other embedded data (custom XMP schemas, document IDs, or printer marks) that may not be fully removed. Use this tool for common privacy clean-up, not as a forensic sanitiser.

Does it work offline?

Yes, once the page has loaded. Because the processing happens on your device, you can disconnect from the network and the tool keeps working. This is the clearest proof that your data never leaves your machine.

Is it free? Do I need an account?

It is completely free and requires no sign-up. There are no watermarks, no daily limits and no tracking cookies needed to use the tool.
