How to Repair PDF – Step by Step

A corrupted PDF that won't open can feel like lost work. The Repair PDF tool attempts to rebuild the file structure so you can recover your content, even when the original file is damaged.

Step-by-Step Guide

Open the Repair PDF page.

Upload your corrupted PDF file.

Click Repair PDF — the tool scans and rebuilds the file structure.

Download the repaired PDF and try opening it in your PDF reader.

Tips for Best Results

• Repair works best on PDFs with minor corruption — headers, cross-references, or missing metadata.
• If the repair doesn't fully recover your file, try the Sanitize tool to remove problematic elements.
• For severely damaged files, the tool may recover partial content — better than nothing!
