Repair PDF
Get a sound copy of a damaged PDF: one that was cut short, lost part of itself, or has a broken index. What the file no longer holds cannot come back.
About This Tool
Repair PDF gives you a sound copy of a PDF. A file that can still be read as it stands is written out afresh, with a newly built index and nothing lost. A file that cannot, because it was cut short in a download, lost bytes on the way or has an index that points to the wrong places, is read piece by piece instead: its pages are found where they lie and put together again.
Each file comes back with a line that says which of these happened and how many pages it has. When the list of pages itself was lost, the pages found are put in the order they lie in the file, and bookmarks and form fields do not survive. What the damaged file no longer holds cannot come back: a page whose content was in the lost part returns empty or not at all, and a picture that is itself damaged stays damaged. A file that is both password-protected and damaged cannot be repaired here.
All processing happens in your browser. You are asked for the password of a protected file when you add it, and the copy that comes back is not protected.

Frequently Asked Questions
Can all PDFs be repaired?
No. A file comes back when its pages are still in it. One that was cut short returns the pages that arrived; one whose every page was in the lost part returns nothing, and the tool says so. A file whose contents were scrambled as a whole, as when every line end was changed in transfer, mostly cannot be mended.
Will all content be recovered?
Only what is still in the file. A page whose content is gone comes back empty, or not at all; where the file refers to something that is no longer in it, that place is left empty. When the list of pages was lost, bookmarks and form fields are lost with it, and the pages are in the order they lie in the file, which is usually but not always their order in the document.
Should I keep the original?
Yes, always keep the original file as a backup.
