What this beta accepts
Metadata is descriptive, not proof. PigPDF separates presence checks from identity, trust and integrity verification.
| Input feature | Current behavior | Reason |
|---|---|---|
| Information dictionary and XMP | Read | Unusually large field lists and values are display-limited. |
| Forms and signature fields | Presence only | Signature validity and field contents are not verified. |
| Embedded JavaScript | Flagged | Actions are detected as data and never executed. |
| Password protection or damage | Rejected | No password entry or repair path is included in this beta. |
Before you use this tool
Questions and limits
Does my file leave this device?
No file content is sent by this tool. The active processing path runs in this browser and is covered by an automated egress test.
Does PigPDF change my source file?
No. This is a read-only inspection. The optional JSON report contains metadata and feature signals, never the PDF bytes.
Which current limits apply?
This local beta creates a separate result in the browser. It rejects encrypted or damaged PDFs, keeps a 100 MB and 250-page guardrail, and does not claim to preserve unsupported interactive structures.
