Frequently Asked Questions

What corruption gets fixed?

Truncated downloads, broken cross-reference tables, and malformed headers — the common download-damage trio. Password-locked files need unlocking first, not repair.

What if pages are missing?

Salvageable pages recover; bytes that never downloaded cannot be invented. A 90%-downloaded file usually opens fully after xref rebuild.

Will formatting survive?

Mostly — text and images recover; complex interactive elements may simplify. Compare page counts before and after as the integrity check.

Is the damaged file uploaded?

No — repair runs locally in your browser. Only the fixed save touches the network — downloads are unlimited.
