How it works:
Our repair engine scans the raw byte structure of the PDF file to identify missing markers, broken cross-reference tables (XREF), and malformed streams. It then attempts to rebuild the document structure so it can be opened normally by standard PDF viewers.

Common Causes of PDF Corruption
- Incomplete Downloads: If your internet connection drops while downloading a PDF, the file may be missing its closing tags, making it unreadable.
- Email Encoding Errors: Sometimes email servers improperly encode attachments, slightly modifying the raw bytes of the PDF.
- Hard Drive Failure: Bad sectors on a hard drive or USB stick can scramble portions of a saved file.
