View common metadata stored in a PDF and remove supported document properties with PKCapra.
PDF files can contain information such as the document title, author, subject, keywords, creator, producer and date fields. These details may be useful when organizing documents, but sometimes you may want to review or remove them before sharing a file.
PKCapra lets you inspect supported PDF metadata and create a cleaned copy directly in your browser.
What Is PDF Metadata?
PDF metadata is information about a PDF document rather than the visible content on its pages.
Depending on how the PDF was created, metadata can include:
- Title
- Author
- Subject
- Keywords
- Creator application
- PDF producer
- Creation date
- Modification date
For example, a PDF created from a document editor may contain the author’s name or the software used to create the file.
Metadata is different from the visible text and images on the PDF pages.

Upload a supported PDF to inspect its common document properties.
PKCapra can display available metadata fields such as:
- Document title
- Author
- Subject
- Keywords
- Creator
- Producer
- Creation date
- Modification date
Not every PDF contains every field. Some metadata may also be stored in formats or structures that this browser-based tool does not expose.
How to View PDF Metadata
1. Upload your PDF
Select your PDF or drag it into the upload area.
2. Inspect the metadata
PKCapra reads supported document properties and displays the available information.
3. Review the information
Check whether the PDF contains an author name, title, keywords, software information or date fields that you want to keep or remove.
How to Remove Metadata from a PDF
If you want to create a cleaner PDF copy:
- Upload the PDF.
- Review the available metadata.
- Choose the metadata-removal option.
- Create the cleaned PDF.
- Download the new copy.
The original PDF remains unchanged.
This is useful because you can keep the original document as a reference while working with a separate cleaned version.
Why Remove Metadata from a PDF?
There are several practical reasons to remove document metadata.
Before sharing a document
You may not want the recipient to see the author name or software information stored in the file.
Before publishing a document
Public documents may contain properties that were never intended to be distributed.
Before submitting a document
Some workflows require documents to contain minimal identifying information.
For document organization
Removing outdated properties can make a PDF cleaner before adding it to a new workflow.
However, metadata can also be useful for records management. Do not remove metadata from an official record simply because it exists. Always follow your organization’s document-retention and compliance requirements.
What PDF Metadata Can Be Removed?
PKCapra focuses on common document metadata fields.
Depending on the PDF, these can include:
- Title
- Author
- Subject
- Keywords
- Creator
- Producer
- Creation date
- Modification date
The exact metadata available depends on how the original PDF was created.
Does Removing Metadata Remove Visible Content?
No.
Removing document metadata is different from editing the visible pages.
If you need to remove visible sensitive information from a PDF, use the Redact PDF tool instead.
Metadata removal deals with document properties.
Redaction deals with information that appears on the actual PDF pages.
PDF Metadata vs PDF Content
A PDF can contain several different types of information.
Metadata describes the document.
Visible content is what appears on the pages.
Embedded objects can include images, fonts and other resources.
Removing common metadata does not automatically remove every piece of information embedded inside a PDF.
For that reason, metadata cleaning should not be described as a complete privacy or forensic-cleaning solution.
Can PDF Metadata Be Completely Removed?
Not always with a simple metadata-removal operation.
PDFs can contain different metadata structures, including document information dictionaries and other embedded or application-specific metadata.
PKCapra removes supported common metadata fields, but it does not claim to perform a forensic sanitization of every possible object or hidden structure inside every PDF.
If a document requires comprehensive sanitization for legal, security or regulatory reasons, use an appropriate specialized document-sanitization workflow.
PDF Metadata Viewer vs PDF Metadata Remover
These are two related functions.
The viewer helps you understand what information is stored in the document properties.
The remover helps you create a cleaned copy by removing supported common metadata.
It is useful to inspect the metadata first so you know what information is actually present.
PDF Metadata vs Redaction
These processes solve different problems.
Metadata removal deals with document properties such as author, title and keywords.
Redaction covers sensitive information visible on the PDF page.
If a PDF contains a person’s address, phone number, account number or other sensitive information on the page itself, removing metadata will not hide it.
For visible sensitive information, use Redact PDF.
PDF Metadata and Document Privacy
Metadata can sometimes reveal information that a document creator did not intend to share.
For example, a PDF could contain:
- A person’s name
- An internal project name
- Software information
- Document creation dates
- Keywords
- Previous document properties
Reviewing metadata before public distribution can therefore be a useful part of a broader document-review workflow.
PDF Metadata and Browser Privacy
PKCapra’s metadata workflow is designed to process the PDF directly in your browser.
That means you can inspect supported metadata without sending the document to a separate online metadata service.
This can be useful for documents containing private information.
However, browser-based processing does not replace your organization’s security requirements. Use appropriate devices and workflows when working with confidential documents.
3. Related PKCapra Tools
If the sensitive information is visible on the PDF page, metadata removal is not enough. Use the Redact PDF tool to permanently cover supported sensitive areas.
If you need to modify other PDF content, the Edit PDF tool provides annotation and markup features.
For adding a visible ownership or confidentiality label, use Watermark PDF.
If you need to protect a PDF with a password after cleaning it, use Protect PDF.
For creating a PDF from an image, you can use the JPG to PDF Converter.
You can also browse the complete collection through All Free Online Tools or explore the site’s Categories.
