Questions about Repair PDF
Frequently asked technical and operational questions about repair pdf.
What types of PDF damage can the repair tool recover?
The repair engine reconstructs broken cross-reference (XREF) tables, recovers orphaned content streams, fixes corrupt page catalog trailers, and re-indexes unreadable page trees.
Can repair recover completely zero-byte or overwritten files?
No tool can synthesize missing bytes if raw data was completely erased. However, if headers or trailers are damaged while stream data remains, repair restores readability.
Where does Repair PDF process my damaged input?
Repair tasks run in secure sandboxed processing containers. Repaired outputs are stored temporarily and purged by scheduled deletion within 30 minutes.
