What does Sanitize PDF do?

It strips hidden data from a PDF: metadata fields (author, creation date, software), annotations (comments, markup), and embedded JavaScript. You choose which categories to remove.

Is my PDF uploaded to a server?

No. Processing happens entirely in your browser. The file never leaves your device.

Will sanitizing change how the PDF looks?

No. Only hidden data is removed. The visible pages, text, and images stay exactly the same. Annotations are the one exception — removing them will remove visible markup like highlights and sticky notes.

What metadata fields are removed?

Title, author, subject, keywords, producer, and creator fields are all cleared. These are the fields that PDF readers show in the document properties panel.

Why would a PDF contain JavaScript?

Some PDF forms use JavaScript for calculations, validation, or auto-filling. Malicious PDFs can also embed scripts that phone home or exploit vulnerabilities. Stripping JavaScript removes both.

Does it work with password-protected PDFs?

Yes. Enter the password to decrypt, then sanitize. Everything runs locally.

About Sanitize PDF

What PDF Sanitization Does

PDFs carry more than visible content. Metadata fields store the author’s name, creation software, edit timestamps, and GPS data from scanning apps. Annotations contain comments and markup. Embedded JavaScript can execute code when the file opens.

Sanitizing strips that hidden layer. You choose what to remove: metadata, annotations, JavaScript — or all three. The tool processes the PDF structure directly, deleting the chosen entries without altering the visible pages.

Why Sanitize Before Sharing

Hidden data in PDFs has caused real problems. Author names in anonymous submissions, GPS coordinates in scanned documents, JavaScript that triggers unwanted behavior.

Strip Author Identity

Remove creator name, software version, and edit history before sharing a document that should be anonymous.

Remove Embedded Scripts

JavaScript in PDFs can open URLs, submit data, or trigger actions on open. Stripping it eliminates that attack surface.

Clear Annotations & Comments

Internal review comments, sticky notes, and markup can accidentally ship with the final document. Sanitize removes them.

Compliance & FOIA Prep

GDPR, FOIA, and internal policies often require scrubbing metadata before public release or document disclosure.

How It Compares

Metadata removal features exist in some PDF editors, but dedicated sanitization with JavaScript stripping is less common.

Sanitization Runs Locally

If you’re stripping metadata to protect identity or comply with a regulation, uploading the un-sanitized file to a third-party server defeats the purpose. The metadata you want removed is exposed during transit.

OxygenPDF processes the file in your browser. The unsanitized document never leaves your device. The cleaned result is generated locally and downloads straight to your machine.
