How does the Repair Corrupted PDF work?
Sometimes a PDF gets corrupted — partial download, an interrupted save, a flaky USB stick, or a tool that wrote a malformed cross-reference table. The result: a PDF that won't open, or opens with errors. This tool runs qpdf's repair pass: re-parse the document, rebuild the cross-reference table, disable object streams (the most common source of corruption), and re-emit a clean, linearised PDF. Many "broken" PDFs come back working perfectly; severely damaged ones may still fail or come back missing pages. Files are processed and deleted right after you download.
