Edit PDF Metadata

About the Edit PDF Metadata

Every PDF carries hidden metadata — title, author, subject and keywords — that shows up in file properties, search results and document libraries. Wrong or leftover metadata looks unprofessional and can even leak information you would rather not share.

This Edit PDF Metadata tool lets you view and update those details in your browser, so your document is described correctly. Nothing is uploaded, so you can clean up sensitive files privately.

How to use the Edit PDF Metadata

1. Add your PDF by dragging it in or clicking to browse.
2. View the current title, author, subject and keywords.
3. Edit the fields to the values you want.
4. Save and download the updated PDF.

How the Edit PDF Metadata works

This tool works directly with the internal structure of your PDF using established open-source engines (pdf-lib and PDF.js) that implement the ISO 32000 PDF specification. Everything runs locally in your web browser through JavaScript, which means the document is read, modified and re-saved on your own device — it is never transmitted to a server. That is what makes the process both instant and genuinely private.

Because the pages are handled at the object level rather than being re-printed, text stays selectable and sharp and images keep their original quality unless you deliberately choose to compress them.

Tips & best practices

• Set a clear, descriptive title — it is often what document systems and search results display, not the filename.
• Check the author field before sending externally, as it can reveal who created or last edited the file.
• Add relevant keywords if the PDF will live in a searchable library or repository.

Standards & accuracy

Built on the PDF (ISO 32000) standard and processed entirely in your browser, so files are never uploaded.

Because processing happens locally, results are consistent and repeatable. For scanned PDFs (images of text with no selectable text layer), text-based operations require OCR first — the tool works with the document's existing text layer.

Who uses the Edit PDF Metadata?

• Setting a proper title and author before sharing
• Removing a previous author's name from a reused file
• Adding keywords for a document library
• Cleaning metadata from a confidential document

Privacy & security

The Edit PDF Metadata runs entirely inside your web browser. Your data — whether that is a file, figures or text — is processed on your own device and is never uploaded to a server, stored or shared. There is no signup and no account, so you can use it as often as you like while keeping full control of your information. This makes it a safe choice even for confidential and sensitive work.
