What this beta accepts
Conservative checks prevent interactive data or signature meaning from being silently lost while a new PDF is created.
| Input feature | Current behavior | Reason |
|---|---|---|
| Standard PDFs | Accepted | Requested pages are processed according to the visible plan. |
| Password protection or damage | Rejected | No password entry or repair path is included in this beta. |
| Forms and signature fields | Rejected | Prevents broken fields and misleading signatures. |
| Source metadata | Not copied | The result receives a clean PigPDF output record. |
| Annotations, links, bookmarks, attachments, labels and actions | Rejected | The beta does not rebuild these document structures safely yet. |
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. The source stays unchanged and PigPDF creates a separate output file.
Which current limits apply?
One PDF up to 100 MB. Only Identity-H/V composite fonts with embedded TrueType, a usable ToUnicode CMap and isolated page/Form text are accepted. Forms, annotations, tagged structures, CFF/Type1 fonts, variable-width CMaps and other unsupported structures are rejected.
