Frequently asked questions

What kinds of damage can this fix?

Truncated downloads, broken cross-reference tables, and missing trailers are the most common causes of a PDF refusing to open — this tool rebuilds the file's internal structure to fix them.

Is every PDF recoverable?

Most structural damage can be repaired. If a file is too severely corrupted, we'll try a fallback recovery method that salvages as many pages as possible before giving up.

Does this work on password-protected PDFs?

Not directly — use Unlock PDF first, then repair the unlocked file.
