Frequently asked questions
What kinds of damage can it fix?
Broken or missing cross-reference tables and similar structural problems. Files that were cut off during download usually cannot be fully recovered.
What if repair fails?
You will be told. In that case the file is too damaged to rebuild in the browser.
Are my files uploaded to your server?
No. This tool runs in your browser using JavaScript that is served from this website. Your file is read on your own device and the result is created there too. File contents are not sent to this website.
Results may differ slightly from the original file. Always check the output before using it.
