Remove Metadata from PDF
Strip hidden author names, timestamps, GPS data, and software information from your PDFs before sharing — protect your privacy.
Every PDF carries hidden metadata — your name, the software you used, when you created or edited the file, and sometimes even GPS coordinates. Before sharing documents publicly or with clients, stripping this metadata protects your privacy and prevents unintended data leaks.
- ✓ Remove author names, company info, and usernames
- ✓ Strip creation and modification timestamps
- ✓ Delete software and version information
- ✓ Remove GPS coordinates and location data
- ✓ Protect against social engineering and data leaks

Privacy Risks of PDF Metadata
When you share a PDF, you may unknowingly share your full name, email address, company name, the software you used, and even your computer's username or network path. This information can be used for social engineering, phishing attacks, or simply to learn more about you than you intended to reveal.
What Metadata Do PDFs Contain?
PDF files typically store a Title, Author, Subject, Keywords, Creator application (like Microsoft Word or Adobe InDesign), Producer (the PDF library used), creation date, modification date, and sometimes custom fields added by enterprise document management systems. Some PDFs also contain revision history and editing timestamps.
When to Strip PDF Metadata
Remove metadata before sharing documents publicly, submitting files to clients or vendors, posting PDFs online, filing documents with courts or agencies, or anytime you want to prevent recipients from seeing who created or edited the file. It is also good practice for GDPR compliance when handling personal data.

Frequently Asked Questions
What is PDF metadata?
PDF metadata is hidden information embedded in the file, including the author's name, creation and modification dates, software used to create the PDF, and sometimes GPS coordinates or company names. This data is not visible on the pages but can be viewed in document properties.
Why should I remove metadata from a PDF?
Metadata can reveal private information like your name, your company, the software you use, or when a document was created or edited. Removing it protects your privacy and prevents unintended data leaks when sharing files publicly.
What metadata do PDFs typically contain?
Common PDF metadata fields include Title, Author, Subject, Keywords, Creator (the application that made it), Producer (the PDF library used), creation date, modification date, and sometimes custom properties added by enterprise software.
Is removing PDF metadata reversible?
No. Once metadata is removed and the file is saved, the original metadata cannot be recovered from the cleaned file. Always keep a backup of the original if you might need the metadata later.
Does flattening a PDF remove metadata?
Flattening a PDF removes form fields, annotations, and layers, but may not remove all metadata fields. For thorough metadata removal, use a dedicated metadata stripping or redaction tool.
Can PDF metadata pose a security risk?
Yes. Metadata can expose internal usernames, network paths, software versions, and revision history. Attackers can use this information for social engineering or to identify software vulnerabilities.
