PDF Document Inspection
PDF (Portable Document Format) files contain far more than visible text and images. They include metadata, hyperlinks, bookmarks, embedded files, digital signatures, and complex document structure. Our viewers extract and display this hidden information.
What's Inside a PDF?
Metadata: Author, title, creation date, software used to create the document, modification history, and custom properties.
Links: Internal navigation links and external URLs embedded in the document, often used in reports and documentation.
Bookmarks: The document outline or table of contents that appears in PDF readers for navigation.
Attachments: Embedded files like spreadsheets, source documents, or supplementary materials packaged with the PDF.
Digital Signatures: Cryptographic signatures that verify document authenticity and integrity.

- Attachment extraction: Retrieve embedded files without Adobe Acrobat Pro

Browser-Based Processing
All PDF analysis happens locally using PDF.js, the same technology that powers Firefox's built-in PDF viewer. Your documents never leave your device, ensuring privacy for confidential contracts, legal documents, and sensitive materials.
