Common questions
Can every PDF be repaired?
No. If nothing can be recovered the tool tells you, rather than handing back a broken file.
How do I know the repair worked?
The rebuilt file is reopened and its pages are displayed, and the result lists what was fixed.
Will my original be overwritten?
No. You download a separate repaired copy.
