- Your file is processed in your browser and is not uploaded to our servers.
Upload a PDF to run a health check (encryption, page count, text layer), then attempt a browser-side rewrite by reloading page content into a new document. This can fix minor structure issues but cannot recover severely corrupted or encrypted files.
100% Client-Side
Your data never leaves your computer.
How to use this tool
1. Upload a PDF that will not open or behaves oddly. 2. Click Repair PDF. 3. Try opening the downloaded rewrite in your viewer. 4. If repair fails, the file may be encrypted or severely corrupted.
Worked example
Example: a PDF that opens with missing pages after a bad download may open correctly after a browser rewrite—password-protected files will not repair here.
