Rebuild a PDF whose internal index is broken, so readers can open it again.
A PDF keeps an index of where everything sits inside the file. If that index is wrong, readers refuse to open the document even though the pages themselves are perfectly fine. Rebuilding the index usually brings the file back.
Worth knowing: This fixes a broken index. It cannot recover data that is genuinely missing, so a file that was cut short during a download or transfer is beyond saving.
Drag the file onto the upload area. Even a file your reader refuses to open can be added.
The tool reads the file directly, works out where the objects really sit, and writes a correct index.
The number of pages recovered is shown, so you can tell straight away whether the document came back whole.
Save the rebuilt file. Your damaged original is left untouched.
This matters more here than almost anywhere else. Sending a document to a server to have its author name stripped means handing that name to the server first. This tool works inside your browser, so the information you are clearing is never transmitted in the first place.
Your original file is also left untouched. The tool builds a new PDF and hands it to you, so you always keep the version you started with.
A PDF stores an index of where every object sits in the file. When that index is wrong, readers refuse to open the document. This tool reads the file anyway, works out where things really are, and writes a correct index.

Data that is genuinely missing. If a file was cut short during a download, an email transfer, or a failed copy, the pages after the cut are simply not there and no tool can bring them back. The tool tells you clearly when this is the case.
The pages, text, and images are carried across as they are. Some interactive extras such as form field appearances may be rebuilt slightly differently, which is the trade for getting a file that opens.
It often does. Rewriting the file structure clears up strange page ordering, slow loading, and errors on save that come from a document having been edited many times by different programs.
No. Everything happens inside your browser on your own device. Your file is never sent anywhere, and nothing is stored.
No. Your original PDF stays exactly as it is. The tool creates a new file for you to download.
