Remove Author & Producer Data from PDFs.

The PDF /Info dictionary stores: Title, Author, Subject, Keywords, Creator (the software that created the source document), Producer (the software that generated the PDF), CreationDate, and ModDate. Our tool clears all eight fields.

Yes. PDF files can contain a separate XMP metadata stream in the document catalog, which duplicates /Info fields and can include additional namespaces (dc:creator, xmp:CreatorTool, etc.). Our tool explicitly deletes the XMP /Metadata stream from the catalog to ensure both sources are purged.

PDFs often save incremental updates that append changes while keeping older revisions inside the file. Our engine re-serializes the whole document structure with pdf-lib, producing a clean, single-revision output.

Our tool loads PDFs with the ignoreEncryption flag, which allows processing of PDFs with owner-level encryption (print/copy restrictions). However, PDFs requiring a user password to open must be unlocked first before metadata can be stripped.

No. pdf-lib re-serializes the document structure without altering page content streams, embedded fonts, images, or the form field structure itself. However, any values entered into form fields (text inputs, checkboxes, dropdowns) are cleared as part of sanitization, since those can contain names, email addresses, and other personal information.

Many PDF generators automatically set the Author field to your OS username, the Creator/Producer fields to software names, and the Title field to the original filename. This can leak internal project names or file paths (like "C:\Users\john\Contracts\Q3_Draft.docx"). Stripping metadata before sharing keeps that private.
