Frequently asked questions
About Repair PDF
Repair PDF tries to open and rebuild PDFs that are damaged, incomplete, or rejected by normal viewers. This can happen after an interrupted download, a broken email attachment, a scanner export that failed near the end, or a file copied from a failing drive. PDF repair is not magic. If the page data is still inside the file but the index or structure is broken, recovery often works. If the file is only a partial download or the important page streams are missing, no tool can recreate the lost content perfectly. After repair, open the output and check page count, text, images, signatures, and forms. For important documents, compare the repaired file with the sender's original if you can get another copy.
