On the free plan you can repair a corrupted PDF with files up to 10 MB and 25 pages. Pro raises this to 200–500 MB and up to 1000 pages, and Lifetime to 1 GB with unlimited pages. Repairing a PDF rebuilds a damaged file's internal structure, recovering as much readable content as possible from a document that won't open.
