Remove PDF metadata

This tool targets the document information dictionary that PDF readers expose under File Properties or Document Properties. It blanks the Title, Author, Subject, and Keywords entries, and resets the Creation Date so it no longer reveals when you first authored the file. Those are the fields most likely to carry your name, your organization, internal project labels, or timestamps you did not mean to publish.

Two fields are not blanked but rewritten: the Producer and Creator entries are both set to "FormatOS" rather than left as your original software (which often names the exact application and version you used). The Modification Date is updated to the moment you run the tool. Everything else about the document, including its pages, text, and layout, is left untouched, so the output opens and prints identically to the original.

Because only the document-level dictionary is rewritten, this is a fast, targeted clean rather than a deep rebuild. If you open the result in a PDF reader afterward and check the properties panel, the author and title lines should be empty and the creation date should read as a neutral default.

Document metadata is only one place information hides in a PDF. This tool does not scrub data embedded inside images, content streams, attachments, form-field defaults, layer names, or any revision history left behind by earlier edits. A scanned page can still carry camera or scanner details in its embedded image, and that data survives this operation untouched.

For that reason, treat the output as cleaned, not anonymized. If you are sharing something genuinely sensitive, such as a leaked-source-risk document or anything tied to a legal or safety matter, do not rely on a metadata strip alone. Review the file manually, consider flattening or re-exporting it, and when the stakes are high consult a specialist who handles document sanitization properly.

One hard limit: encrypted or password-protected PDFs cannot be processed. The file has to be readable for the tool to load and rewrite its properties. If your PDF is protected, remove the password in your PDF reader first, then run it through here.

The workflow is deliberately plain. Drop or choose a single PDF, confirm the page count shown after it loads, then press Remove Metadata. There are no sliders or text fields to set, because the cleared fields are fixed, so there is nothing to misconfigure. When it finishes you download a new PDF with a "-remove-pdf-metadata" suffix; your original file on disk is never altered.

All of this happens inside your browser. The PDF is read into memory, its properties are rewritten locally, and the new file is handed back to you as a download. Nothing is uploaded to a server, which matters here more than on most tools, since the whole point is keeping identifying information off a file before it travels. The generated download link is also cleaned up automatically after a short while.

A practical tip: keep your original. Once metadata is cleared it is gone from the copy you share, and there is no companion tool to put the author or title back. If you might need those details later, archive the untouched source file before running the clean, and verify the result in your reader's properties panel before you send it on.
