How to Inspect PDF Document Properties Online
Read internal author tags, security attributes, and creation dates in milliseconds.
Load PDF Document
Drop any PDF file into the viewer. The file remains strictly inside your local device memory.
Parse Header & XMP
Client-side WebAssembly inspects document trailer dictionaries, objects, and metadata streams.
Analyze Properties
Review timestamps, creator software, dimensions, and permissions in a structured property tree.
Why Professionals Inspect PDF Metadata
Ensure legal validity, protect operational security, and verify technical standards.
Legal Discovery & Forensics
Verify timestamp claims on disputed agreements, confirm software producers, and check if a contract was altered post-signing.
Privacy Sanitization & OPSEC
Audit documents before public publication to prevent leaking internal author usernames, office server filepaths, or company software details.
Pre-Flight Print Inspection
Print production shops check exact page bounding box dimensions (BleedBox, TrimBox) and PDF specification compliance before high-volume runs.
Academic & Journal Compliance
Ensure research theses and manuscripts meet university or journal digital archiving requirements, including proper subject tags and keywords.

No. The entire PDF binary header and XMP metadata streams are parsed directly in your local browser memory via WebAssembly. Your document never leaves your machine.
Yes. PDFs.lol extracts both the original CreationDate and ModDate records stored within the PDF dictionary, complete with original UTC timezone offsets.
