The Best Way to Repair PDF Files

Recovering a corrupted PDF file shouldn't be complicated. ToolifyPDF provides a powerful solution to repair broken or damaged PDF documents directly in your web browser. Whether your file was damaged during download, transfer, or storage, our tool attempts to recover your content quickly and for free. After repair, you can use our Organize PDF tool to verify and reorder the recovered pages.

Fix Structural Errors

Our advanced algorithm scans the PDF for structural inconsistencies, broken cross-reference tables (XREF), and invalid objects, rebuilding them to restore the file's integrity.

Recover Content

We prioritize recovering the readable text and images from your document. In many cases, even if the entire structure cannot be saved, the core content can be extracted and placed into a new PDF.

How to Repair a Corrupted PDF

  1. Upload: Click "Select PDF File" or drag and drop your corrupted document into the box.
  2. Analyze: Our tool automatically starts analyzing the file structure.
  3. Repair: The system applies fixes to corrupted segments and rebuilds the document.
  4. Download: Once repaired, download your recovered PDF file instantly.
