Frequently Asked Questions

What details does it show?

Page count, file size, dimensions, author, creator app, creation/modification dates, and encryption status — the full header in one glance.

Can it detect locked PDFs?

Yes — encryption and permission flags report upfront (no-print, no-copy). Unlock first with the password before editing or converting.

Why check before opening?

Oversized page counts and producer anomalies flag malformed or malicious files. A 2-page invoice claiming 400 pages deserves suspicion, not a double-click.

Does inspecting a PDF upload it?

No — header parsing runs locally in your browser. Nothing leaves your device and nothing is stored.
