Tips
- A file that was cut off during a download may be missing pages entirely. Download it again if you can.
- If it's password protected, unlock it first with Unlock PDF.
Questions
- Can every PDF be repaired?
- Not always. Repair fixes damaged structure, but it can't recreate content that was never saved, like the missing end of an interrupted download.
- Will repairing change how the pages look?
- No. It rebuilds the file around the same content.
