  4. Check the "Page Geometry" tab to inspect exact page dimensions in points, inches, and millimeters, plus automatic ISO paper size detection (e.g. A4, US Letter, Legal).
  5. Inspect raw Adobe XMP Extensible Metadata Platform XML packets under the "XMP Raw XML" tab with 1-click XML copying.
  6. Switch to the "Edit & Sanitize" tab to customize document properties or click "Wipe / Sanitize All Metadata" to remove all author fingerprints before sharing.

Document Forensics & Verification

Inspecting PDF metadata reveals essential provenance information including the original authoring software (e.g. Microsoft Word, Google Docs, InDesign), PDF conversion engines (e.g. Quartz, Distiller, Toolique), creation timestamps, and linear fast web view flags.

Privacy Sanitization Before Public Document Sharing

Before publishing contracts, academic papers, or legal exhibits online, cleaning hidden metadata fields is a vital cybersecurity and privacy practice. Toolique lets you sanitize all author identifiers directly in your browser with zero data loss.

Frequently Asked Questions

Are my confidential documents uploaded to any server during metadata inspection?
Never. All PDF parsing, thumbnail rendering, and metadata extraction take place 100% locally inside your browser memory using WebAssembly. No files, tags, or metadata strings are ever transmitted over the network.
Can I edit the PDF metadata and download an updated file?
Yes! Under the "Edit & Sanitize" tab, you can modify the Title, Author, Subject, Keywords, Creator Software, and Producer Engine. Clicking "Update & Save PDF" compiles an updated PDF file losslessly without re-compressing or modifying your document contents.
How does the "Wipe / Sanitize All Metadata" feature protect my privacy?
PDF files created by word processors, design software, or scanners often embed hidden author names, company affiliations, computer usernames, software serials, and precise creation timestamps. Sanitizing wipes all these tags clean, ensuring zero accidental metadata leaks when publishing documents publicly.
What is the difference between the /Info Dictionary and XMP Metadata?
The `/Info` dictionary is the classic PDF metadata structure stored in the document trailer catalog. XMP (Extensible Metadata Platform) is an ISO standard XML-based data stream embedded by modern tools like Adobe Acrobat and Photoshop to store Dublin Core, PDF/A, and rights management schemas.
Can I inspect physical page dimensions and paper sizes?
Yes. The Page Geometry tab calculates the exact width and height of each page in points (72 pt = 1 inch), inches, and millimeters, and automatically identifies standard paper formats like A4, US Letter, Legal, A3, and Tabloid.
Can I export the metadata for programmatic use or audits?
Yes. You can export the entire extracted metadata payload as a formatted JSON document (`.json`) or a spreadsheet-ready CSV table (`.csv`) with a single click.
