Features
Deep Structure Analysis
The repair engine scans the raw byte stream for valid PDF objects, rebuilding the cross-reference table and page tree from scratch.

Even severely damaged files may yield partial content. The tool extracts every recoverable page and assembles them into a new valid PDF.
Compatibility Restoration
Repaired PDFs conform to the PDF specification so they open reliably in Acrobat, Preview, Chrome, Firefox, and mobile readers.
