Recover a corrupted PDF file
If a PDF will not open, shows an error or was cut short during a download, this tool tries to rebuild it. It reads whatever is still intact, reconstructs the internal structure of the file and saves a fresh copy that PDF readers can open. Not every file can be saved: content that is missing from the file cannot be brought back. The repair runs on your own device, so a sensitive document is not sent anywhere.
Good to know
Answers to common questions about Repair PDF.
What kind of damage can be fixed?
Broken cross-reference tables, missing end-of-file markers and files cut short during download can usually be rebuilt. Content that is missing from the file cannot be brought back.
What happens if the structure cannot be rebuilt?
As a last resort the readable pages are saved as images so you can still see and print them. You are told when this happens.
Is my file uploaded anywhere?
No. Repair PDF runs inside your browser tab and your file never leaves your device. Close the tab and nothing remains.
