Frequently Asked Questions About Repair Pdf

File Recovery

What types of PDF damage can this tool fix?

It can repair PDFs with corrupted XREF tables, missing EOF markers, broken metadata, and stream formatting errors that typically cause 'File cannot be opened' errors in Adobe Reader.

Can it recover a file that is 0 bytes or completely empty?

No. If a file is 0 bytes, the data is entirely missing from your hard drive. This tool requires at least some residual data structure to rebuild the document.

Will it recover all my pages perfectly?

While it has a high success rate for structural damage, severe data corruption might mean some pages, images, or fonts are permanently lost and cannot be fully reconstructed.

Process & Limitations

Does repairing the PDF alter the original content?

The tool strictly attempts to rebuild the file's scaffolding so it can be opened. It does not alter the actual text, images, or layout of the surviving content.

Why does my repaired PDF look slightly different?

If the original file had corrupted embedded fonts, the repair engine may have stripped them to make the file readable, causing your viewer to substitute them with standard system fonts.

Can I repair a password-protected file that got corrupted?

If the encryption dictionary itself is corrupted, the file is usually unrecoverable. If the encryption is intact, you will need the password to open the file even after a successful structural repair.
