Try to fix a PDF that won't open properly — free, best-effort.

Frequently asked questions
Will this always work?
No — if the file is damaged badly enough that it can't be parsed at all, there's nothing to rebuild from. This tool works best on files with a broken page index or other structural issues, not files with missing/corrupted page data itself.
Will my content or formatting change?
No — each page's content is copied through exactly as-is; only the PDF's internal structure is rebuilt.
