Repair a corrupted PDF: what was wrong and what came back

Choose the PDF that won't open: the tool reads the file before touching it and names the defect (cut-off download, index in the wrong place, swapped line breaks). Then it rebuilds the pages without relying on the index and shows, page by page, what came back with text and what was not in the file.

Your PDF never leaves your device

The file

Everything happens in this tab; your file does not change, a repaired copy comes out.

The repair

  1. Reads the objects one by one, without relying on the index.
  2. Rebuilds the page list with the pages that are in the file.
  3. Writes a new index, trailer and %%EOF and checks the result.
