Frequently Asked Questions
Everything you need to know about formats, browser privacy, and file handling.
What document metadata is stored inside a PDF file (Title, Author, Subject, Keywords)?▼
PDF files store two metadata structures: standard Document Information dictionary (Title, Author, Subject, Keywords, Creator, Producer, Creation Date) and extensible XMP (Extensible Metadata Platform) XML streams used by search engines and archiving tools.
How do I remove hidden personal data and author info before sharing a PDF?▼
Upload your document to our editor and click 'Strip All Metadata' or clear specific fields like Author, Company, and File Path history. This scrubs sensitive internal employee names and software versions before public distribution.
Why does my PDF show the wrong document title in browser tabs, and how do I fix it?▼
Web browsers display the internal 'Title' metadata field in the tab header rather than the filename. If a document was saved from an old template, it may show an outdated title. You can update the Title field to match your intended document name.
What is the difference between standard Document Info and XMP metadata?▼
Document Info is the classic PDF 1.0 metadata dictionary. XMP is an ISO-standardized XML block introduced by Adobe that synchronizes with graphic design software, digital asset managers, and search engine crawlers.
Can editing PDF metadata improve SEO ranking for documents published online?▼
Yes! Search engines like Google index the Title, Subject, and Keywords metadata fields. Setting a keyword-rich, descriptive Title directly improves search snippet appearance and organic click-through rates.
How do I update the Creator, Producer, and Creation Date fields?▼
Our editor gives you complete access to view and modify Creator (the originating authoring application), Producer (the PDF generation library), and Creation/Modification timestamps.
Does editing metadata recompress or alter the visual content of the PDF?▼
No. Updating metadata only modifies the header dictionary and XMP data streams. The visual page content, image streams, and vector layouts are untouched and 100% preserved.
Can I view and edit custom metadata fields or copyright notices?▼
Yes. You can add custom key-value pairs (such as 'Copyright: © 2026 Company Inc.' or 'DocumentClassification: Public') for digital rights management and enterprise cataloging.
Can I edit metadata on password-protected PDF files?▼
If the document is protected, you must enter the owner password to authorize metadata changes. Once unlocked, you can save your updated metadata.
Are uploaded PDF files inspected or permanently logged when modifying metadata?▼
No. Uploaded files are processed in ephemeral sandboxes and removed immediately upon download. We never inspect or store your document properties.
