Repair PDF
Recover readable PDFs by rebuilding their structure or salvaging renderable pages. Processing stays in your browser.
Attempt to recover a damaged or corrupted PDF by rebuilding its internal structure, or by rasterizing whatever pages PDF.js can still render into a fresh, openable document. Useful when a PDF was truncated during a download, corrupted during transfer, or throws an error in every viewer you try. Repair works locally in your browser, and success depends on how much of the original file structure survives - not every damaged PDF can be recovered.

Common questions
Can every damaged PDF be repaired?
No. Recovery requires either a readable PDF structure or pages that PDF.js can still render.
What does raster recovery change?
It preserves the visible pages, but selectable text, links, forms, and vector objects become page images.
Is my file uploaded during repair?
No - both structural rebuild and raster recovery run locally in your browser.
What if repair fails completely?
If PDF.js cannot render any pages and the structure cannot be rebuilt, the file is likely too severely corrupted to recover with a browser-based tool.
