How Does PDF Repair Work?

1. Structural Rebuilding: This tool doesn't magically recover lost data. Instead, it attempts to fix a damaged PDF by using a powerful engine to read whatever content is still accessible and rebuild it into a new, valid PDF file.
2. Select Your Damaged PDFs: Drag and drop your potentially corrupted PDF files into the upload area. The process is completely secure and done in your browser.
3. Automatic Repair Process: The tool will automatically try to open and re-save each PDF. This process often fixes common issues like faulty cross-reference tables or incorrect file structures.
4. Download and Verify: After processing, download the new files and check if the content has been recovered. Success depends on the type and severity of the original damage.
