Frequently Asked Questions
What types of PDF corruption can this tool fix?
This tool can fix broken cross-reference tables, corrupt trailer dictionaries, incorrect byte offsets, missing EOF markers, and damaged page tree structures. These are the most common types of PDF corruption.
Is my PDF file uploaded to a server?
No. All processing happens entirely in your browser. Your PDF file never leaves your device, ensuring complete privacy and security.
What does "partially recovered" mean?
When a PDF is severely damaged, our tool falls back to rendering each page as an image and rebuilding the PDF. The visual content is preserved but text may not be selectable in the repaired file.
Can this tool fix password-protected PDFs?
This tool is designed to fix structural corruption, not to remove password protection. If your PDF is password-protected and also corrupt, you may need to provide the password first using an unlock tool.
What if the repair fails?
If both repair methods fail, the file may be too severely damaged to recover. This can happen with truncated files where content data is physically missing, or files that are not actually PDFs.
