Frequently asked questions
What can be repaired?
Broken cross-reference tables, wrong offsets, missing or damaged trailers, wrong stream lengths and damaged objects — the most common causes of PDFs that do not open after an interrupted download or a faulty program.
Can every PDF be saved?
Not always. If the page content itself is missing, nothing can bring it back; the tool then keeps every page it can still read.
Is my original changed?
No. You download a repaired copy; the original stays on your device as it was.
