Repair a PDF

Recover a damaged PDF

Where it runs: On the server.

Drop a file to begin.

This tool needs software that does not run in a browser. The file is sent over an encrypted connection, processed, then deleted automatically after two hours. Nobody reads it.

What this tool does

Rebuilds the object table of a file no reader will open any more: an interrupted transfer, a failing disk, a botched export. What is genuinely lost cannot be invented, but structure often can be repaired.

Frequently asked questions

When does repair actually work?
When the structure is damaged but the content is there: an interrupted transfer, a failing disk, a botched export, a download cut short. The table that says where to find each object is rebuilt from the file itself.
Can a truncated file be recovered?
Partly. What was never written cannot be invented: a file cut off two thirds of the way through will return at best the first two thirds of its pages. That is often better than nothing.
My file opens but displays badly. Is this the right tool?
Not necessarily. A blank page or scrambled characters more often come from a missing font than from corruption. Try opening the document in another reader first.
