Repair PDF
A PDF that suddenly won’t open, or opens with missing pages and rendering errors, is usually a structural problem rather than lost content. Repair rebuilds the file cleanly first, and falls back to recovering pages as images when the damage is too deep for a clean rebuild.

Frequently asked questions
What causes a PDF to become corrupted?
Interrupted downloads, buggy export tools and incomplete file transfers are the most common causes.
Will repair always fix my file?
Not always — some damage is unrecoverable. The image fallback recovers whatever still renders even when the underlying structure can’t be rebuilt.
Does the image fallback keep selectable text?
No — pages recovered as images look identical but lose the text layer.
Is my file uploaded anywhere to be repaired?
No, the rebuild runs entirely in your browser.
