PDF corruption commonly occurs when a file download is interrupted, an email attachment is incorrectly encoded, or an old hard drive develops bad sectors. Acrobat readers reject these files because the xref catalog points to invalid byte offsets.
Our repair algorithm scans the raw PDF binary streams, extracts intact page objects, rebuilds the cross-reference index from scratch, and emits a clean, standard-compliant PDF document.
