What kinds of problems can this fix?
Structural issues — a broken or stale internal index, dangling references, and similar damage that stops some readers from opening the file cleanly.
Can every broken PDF be repaired?
No. A file that's badly truncated or isn't a real PDF at all can't be recovered. When the internal structure can't be rebuilt but the pages can still be displayed, they're recovered as page images instead so you don't lose the content, though the text is no longer selectable.
Is my file uploaded anywhere?
No. Every recovery attempt happens locally in your browser.
