Frequently Asked Questions
Quick answers to common questions
Can all PDFs be repaired?
Not all damage is repairable. Our tool fixes many common issues but severely corrupted files may have unrecoverable content. We'll show you what can be recovered.
Will all content be recovered?
We recover as much as possible. Some heavily damaged sections may be lost, but we preserve everything that can be reconstructed.
Is the repair process safe?
Yes, repair creates a new file. Your original (damaged) file is not modified, so you don't risk further damage.
Why won't Adobe Reader open my PDF?
PDF readers are strict about file format. Our repair tool is more forgiving and can often fix issues that cause readers to reject files.
Does repair affect quality?
Repair preserves original quality of recoverable content. The goal is to reconstruct the original file, not modify it.
What types of corruption can be fixed?
Header corruption, cross-reference errors, incomplete streams, damaged catalog, and many structural issues. Physical media damage that destroyed data cannot be recovered.
