What Is the Repair PDF Tool?
The Repair PDF tool helps rebuild readable pages from a damaged, partially corrupted or difficult to open PDF into a fresh PDF file. It processes the document page by page, renders the readable content and creates a new image based PDF.
This free PDF tool is useful when a PDF has loading problems, broken pages, display errors or structural issues that prevent it from opening correctly in some PDF readers. The tool can attempt to recover every readable page while skipping pages that cannot be processed.
You can choose between two repair modes. The first repairs readable pages and skips failed pages. The second stops the entire process if any selected page cannot be rebuilt.
The repaired document preserves the visible appearance of readable pages. Because the pages are rebuilt as images, selectable text, searchable text, editable forms, links, bookmarks and some interactive features may not remain available.
When Should You Repair a PDF?
A PDF may become difficult to open after an incomplete download, unreliable transfer, outdated export process or partial file damage.
- A PDF opens with missing pages
- Some pages display as blank
- A PDF reader reports a damaged file
- The document freezes while opening
- Certain pages cannot be rendered
- The PDF works in one browser but not another
- A scanned document has structural errors
- You need to recover readable pages from a partially damaged file

Choose the repair mode, enter the pages you want to process, add a password if the PDF is locked, select the output quality and set the file name. Click Repair PDF to begin.
The tool attempts to render each selected page and records whether it was repaired or skipped. After processing, review the totals before downloading the new PDF.

Real Before and After Example
A 20 page scanned contract opens slowly. Pages 8 and 14 produce display errors, and some PDF readers refuse to open the document.
The user chooses skip mode and Recommended quality. The tool rebuilds 18 readable pages and omits the two pages that cannot be rendered, creating a fresh PDF that opens more reliably.

Privacy and File Security
The PDF is processed directly inside your browser. Your document is not uploaded to an external server during normal processing.
The tool creates a new repaired copy and does not overwrite the original file. Keep the original until you have checked the repaired document because unreadable pages may be skipped.
Limitations and Troubleshooting
This tool cannot repair a PDF that the browser cannot read at all. Severely corrupted files, missing page data, unsupported encryption or incorrect passwords may prevent recovery.
- Confirm that the file is a PDF.
- Enter the correct password when required.
- Select skip mode for partial recovery.
- Process fewer pages if the browser struggles.
- Choose Recommended or Small Size quality.
- Use an updated browser.
- Close other memory intensive tabs.
- Try a smaller file.
