Frequently Asked Questions

PDF metadata is background information embedded inside a PDF file. It includes standard document properties like the title, author name, subject, creation date, modifications logs, and technical metrics like PDF version, page layouts, security restrictions, and embedded font directories.

Inspecting PDF properties helps you verify a document's origin, confirm copyright or authoring attributes, and check technical settings (like page ratios, image quality, or missing embedded fonts). Most importantly, reviewing metadata is crucial for privacy before sharing files publicly to ensure they do not expose sensitive local system paths, author names, or internal software builds.

No. ToolZeno processes all actions completely locally on your device. The PDF parsing, font catalog index scans, and metadata extractions execute inside your browser sandbox memory using Web Workers. No network packets or document bytes ever leave your device.

Locked or password-secured PDF documents cannot be parsed until they are decrypted. If you attempt to upload a locked file, the tool will trigger validation alerts and suggest that you unlock the PDF using a decrypter utility first before scanning its metadata structure.
