Frequently asked questions
How do I repair a corrupted PDF?
Choose the damaged PDF and select Repair. The tool tries three methods in turn: rewriting the file structure, rebuilding it with the qpdf recovery engine, and, as a last resort, drawing every readable page into a new PDF.
Why does the report mention a method?
So you know what changed. “pdf-lib” and “qpdf” keep text and links; “rasterised” does not.
Is my PDF uploaded anywhere?
No. The PDF is processed by JavaScript in your browser. Only the website's own code and assets are downloaded, and you can check this in your browser's network panel.
Do I need to create an account?
No. Every tool works without sign-up or login.
Is it safe for confidential documents?
Files are processed locally in your browser and never uploaded. Close the tab or select Clear to release them from memory.
