Frequently Asked Questions
What types of PDF issues can be repaired?
We can fix corrupted headers, broken cross-references, damaged object streams, font embedding issues, invalid metadata, structural errors, and files that won't open or display incorrectly.
What is the difference between repair modes?
Light mode fixes minor issues while preserving the original structure. Auto mode analyzes the file and applies appropriate fixes automatically (recommended). Deep mode completely rebuilds the PDF structure for severely damaged files.
Can all corrupted PDFs be repaired?
Most issues can be fixed successfully. However, severely damaged files or PDFs where the actual content data is corrupted may lose some elements. We recover as much content as possible.
Will I lose any content during repair?
The repair process preserves as much content as possible. In most cases, all content is recovered. For severely damaged files, some elements may not be recoverable.
Can I repair password-protected PDFs?
If the PDF is encrypted and corrupted, you'll need the password to repair it. Use our Unlock PDF tool first if you know the password, then repair.
Why did my PDF become corrupted?
PDFs can become corrupted due to incomplete downloads, storage device errors, software crashes during editing, email transmission issues, or virus damage.
Is the PDF repair service free?
Yes, our PDF repair tool is completely free to use with no registration required.
Are my files secure?
Absolutely. We use 256-bit SSL encryption for all transfers. Files are automatically deleted within 1 hour after processing.
