Rebuilds a broken cross-reference table to recover a file that won't open.

Up to 100 MB. Both the upload and the result are deleted an hour later.
Even one that other readers refuse to open.
The cross-reference table is reconstructed from the objects actually present.
You are told what was found and how many pages were recovered.
The common kind: a broken cross-reference table, usually from an interrupted download or a crash mid-save. The page content is intact but the index pointing at it is not, and that index can be rebuilt.
Genuinely truncated files. If the download stopped halfway, the missing bytes do not exist anywhere and no tool can invent them - though you may still recover the pages that did arrive.
Whatever is recoverable comes back unchanged. If some objects are unsalvageable, you may lose particular images or fonts, and the tool tells you how many pages were recovered.
Yes. Files that open with a warning usually have minor structural damage, and re-saving through a rebuild often clears it permanently.
Recover a PDF that will not open by rebuilding its internal structure. The most common failure by far is a damaged cross-reference table - the index that tells a reader where each object lives - usually caused by an interrupted download or a crash during save. The page content is generally intact, and that index can be reconstructed from the objects actually present in the file. Genuinely truncated downloads are the limit: missing bytes cannot be invented, though the pages that did arrive can often still be salvaged.
