PDF Metadata Remover - Strip Author, Title & Properties

The standard document information dictionary typically records the Title, Author, Subject, Keywords, Creator application, Producer application, and the creation and modification dates. Depending on how the file was produced it may also carry a full name or username in the author field, the name of your company, the internal project or client the document belongs to, an editing history of earlier revisions, bookmark and outline titles, form field contents, embedded JavaScript, attached files and an XMP packet that duplicates the same details in a machine readable form. Because none of this is page content, selecting all the text and deleting it removes none of it. Any of these fields can identify you, your employer or your client to a stranger who receives the document.

Because most editors do not preserve the metadata you removed, they replace it. Word, Google Docs, LibreOffice and similar applications re-stamp the author with the current user name and the producer with their own application string every time they save, and doing so also writes a new modification timestamp. Even an edit that changes nothing meaningful will refresh those fields, so a document you carefully cleaned becomes identifiable again after a single round trip through an editor. This is why the correct order of operations is to do all your editing first and strip the metadata last, immediately before sharing. If you must edit after cleaning, strip again rather than assuming the previous clean state survived.

No. The document information dictionary and the XMP packet are stored separately from the page content stream, so removing them leaves every glyph, image, vector drawing, table and layout exactly where it was. Page count, page size and rotation are preserved, and the file opens and prints identically in any conforming reader. What you are giving up is only the descriptive information about the file itself, such as its title in the reader properties panel and its author listing. If a document relies on an embedded JavaScript action or an attached file to function, removing that is a deliberate content change rather than a metadata change, so treat those categories separately and be aware that the affected interactive behaviour will no longer run.

Not with this tool. The document is read using the browser's own file APIs and rewritten by client-side JavaScript, so the bytes travel from your disk into the page and back into a download without passing through any remote server. That distinction is important for confidential material: contracts, medical records, legal discovery, unreleased financial reporting and anything under an NDA would be exposed to a third party by an upload-based service, regardless of whether that service claims to delete the file afterwards. Verify that any tool you use performs processing client-side, and treat the absence of any upload as a requirement rather than a nice-to-have when handling sensitive documents.

For anything leaving your organisation, yes, and there is very little downside. The only reason to keep metadata is if the descriptive fields serve a purpose your readers depend on, such as a meaningful title and author on a published white paper where the authorship is meant to be public, or an internal document library that indexes files by their title property. For contracts, invoices, medical and legal records, evidence submitted to a public docket, resumes, academic submissions with blind review, bug reports and internal drafts, removing the fields is the correct default. Set aside twenty seconds before you attach the file, because the cost of discovering a leak after the document has been shared is far higher than the cost of cleaning it beforehand.

No, and it is worth being precise about this. Metadata removal strips the identifying fields that most casual sharing exposes, but a PDF can still contain identifying material that has nothing to do with the Info dictionary, including text or images of your face inside the page content, a signature image, metadata that survived in an incremental update section, identifying information in embedded fonts or colour profiles, and traces of the original file in its internal structure. For most everyday sharing, clearing the metadata removes the realistic risk. For genuinely sensitive material, combine this step with a visual review of every page, and check whether the document contains handwritten annotations or scanned pages that reveal more than the fields ever did.
