Question 1

What does PDF Repair do?

Accepted Answer

PDF Repair diagnoses common PDF structure problems and attempts to load and rebuild a readable copy directly in your browser.

Question 2

Can PDF Repair fix every corrupted PDF?

Accepted Answer

No. Some severe PDF corruption cannot be repaired in a browser, especially when essential objects or compressed streams are missing.

Question 3

Is my PDF uploaded to a server?

Accepted Answer

No. The repair process runs in your browser. The tool does not need to upload the PDF to a repair server.

Question 4

What problems can the tool detect?

Accepted Answer

It checks the PDF signature, file size, EOF marker, trailer-related structure and whether the PDF can be parsed and rebuilt.

Question 5

What does recovery mean?

Accepted Answer

Recovery means the tool attempts safe structural corrections and then tries to create and validate a new PDF from the readable document structure.

Question 6

Will the repaired PDF look exactly like the original?

Accepted Answer

When rebuilding succeeds, the readable pages are preserved as far as the PDF parser can recover them, but damaged metadata or unsupported features may not be identical.

Question 7

Can I repair a password-protected PDF?

Accepted Answer

Encrypted or password-protected PDFs may require the correct password and may not be recoverable by this browser-based workflow.

Question 8

Does PDF Repair keep my original file?

Accepted Answer

The original file is not modified. The tool creates a separate repaired copy when recovery succeeds.

Question 9

What happens if repair fails?

Accepted Answer

The tool shows a diagnostic result instead of generating a file that it cannot validate.

Question 10

Is PDF Repair free?

Accepted Answer

Yes. The tool is designed as a free Cobriums browser utility with no account or API key required.
