Questions

What can be fixed?

Broken cross-reference tables, junk before the header, wrong stream lengths, damaged page links. The result is re-checked against qpdf's structural test.

What can't be fixed?

Bytes that aren't there. If a download stopped midway, the missing tail is gone — re-download the original instead.

Is my file uploaded anywhere?

No. Repair runs entirely on your device, like every LocalPDF tool.
