What types of PDF damage can this tool fix?

It can repair PDFs with corrupted XREF tables, missing EOF markers, broken metadata, and stream formatting errors that typically cause 'File cannot be opened' errors in Adobe Reader.

Can it recover a file that is 0 bytes or completely empty?

No. If a file is 0 bytes, the data is entirely missing from your hard drive. This tool requires at least some residual data structure to rebuild the document.

Will it recover all my pages perfectly?

While it has a high success rate for structural damage, severe data corruption might mean some pages, images, or fonts are permanently lost and cannot be fully reconstructed.
