What is PDF Metadata?
PDF metadata consists of document properties and background attributes embedded within a PDF file. Common metadata fields include the document title, author name, subject, keywords, creation application (Creator), generation software (Producer), creation timestamp, and modification history. PDFZento lets you remove PDF metadata online for free on-device in your web browser before sharing or distributing files, clearing supported properties without sending your documents to remote servers.

Why Remove PDF Metadata Before Sharing?
Whenever you create, export, or print a PDF from word processors, presentation software, or design tools, background information is automatically saved into the document properties. This hidden data can unintentionally reveal:
- Author name and usernames: The personal account or login name of the person who drafted or exported the file.
- Software environment: The specific word processor, PDF driver, or operating system used to generate the document (Creator and Producer tags).
- Document titles and working drafts: Internal project names or subject lines that were not meant for public dissemination.
- Creation and modification timestamps: The exact date, time, and timeline of document edits.
Using an online tool to strip PDF metadata helps you clean document properties before sending files to clients, publishing reports publicly, or submitting academic papers for blind peer review.
Metadata Removal vs. Full Document Sanitization
Understanding the distinction between removing PDF metadata and full document sanitization is critical for document security:
| Component | What It Contains | Handled by this Tool? | Recommended Solution |
|---|---|---|---|
| Document Properties (Info Dictionary) | Author, Title, Subject, Keywords, Creator application, Producer, Creation and Mod dates | Yes — Fully Cleared | Use this tool before distributing or publishing PDF documents. |
| Visible Body Text & Graphics | Printed names, signatures, addresses, phone numbers, account figures | No — Untouched | Use Redact PDF to permanently black out confidential visible text. |
| Interactive Form Fields & Annotations | Fillable input widgets, checkboxes, comments, sticky notes | No — Form remains active | Use Flatten PDF to bake interactive fields into static page vectors. |
| Embedded Objects & File Attachments | Attached supplementary files, multimedia, raster image EXIF tags | No — Unaltered | Use PDF Inspector to inspect technical document streams and properties. |
Remove PDF Metadata on Mac, Windows, and Linux
Whether you need to remove pdf metadata on Mac, Windows, or Linux, PDFZento works directly inside any modern web browser including Safari, Chrome, Firefox, and Edge.

Frequently Asked Questions
What is PDF metadata and what information is stored in it?
PDF metadata consists of document properties and header attributes embedded inside the file. It typically includes the document title, author name, subject, keywords, creation application (Creator), PDF generation software (Producer), creation timestamp, and last modification date.
How do I remove metadata from a PDF file?
To remove metadata, select your PDF file or drag it into the PDFZento tool above, then click "Process Remove PDF Metadata". PDFZento clears the document info dictionary (Title, Author, Subject, Keywords, Creator, Producer, and timestamps) completely in your browser. When finished, download your cleaned PDF file.
Can I remove PDF metadata online for free?
Yes. PDFZento provides a 100% free online PDF metadata remover. It runs locally inside your modern web browser using client-side JavaScript and WebAssembly, meaning no file uploads to external servers, no account registration, and no service fees.
Can I remove the author name from a PDF?
Yes. PDFZento resets the Author field in the document information dictionary to empty, removing the author name and personal attribution tags from the document properties before you distribute or publish the file.
Can I remove PDF document properties on a Mac?
Yes. Because PDFZento is an in-browser web application, you can remove PDF metadata on Mac using Safari, Google Chrome, Mozilla Firefox, or Microsoft Edge. It operates directly in macOS browsers with no desktop software installation or command-line tools required.
Does removing metadata delete visible page text, images, or signatures?
No. Removing document metadata only clears invisible file properties and header tags. Visible body text, photographs, vector graphics, scanned pages, and printed signatures remain entirely unaltered. If you need to obscure visible personal information on pages, use Redact PDF.
Does removing PDF metadata remove all hidden information (full document sanitization)?
No. Metadata removal strips document information dictionary properties (author, title, timestamps, creator). It does not perform full document sanitization: it does not remove embedded file attachments, interactive form fields, annotations, JavaScript, or hidden text layers. If you need to flatten interactive form widgets into static graphics, use Flatten PDF.
Does removing PDF metadata make a document completely anonymous?
No. Stripping metadata removes author and application tags from document properties, but it cannot remove identifying names, phone numbers, or corporate addresses written directly in the visible page content or headers. Always review document page contents before sharing files where privacy is sensitive.
What specific metadata fields does PDFZento remove?
PDFZento neutralizes the standard Document Information Dictionary fields: Title, Author, Subject, and Keywords are cleared to blank strings; Creator and Producer are set to generic engine identifiers; and CreationDate and ModDate are reset to standard epoch zeros.
Are my PDF documents uploaded to a server when removing metadata?
No. PDFZento processes documents entirely on your local device within browser memory. Your confidential files and metadata records are never transmitted across the internet, stored on remote databases, or inspected by third parties.
