Privacy
Input and files are processed in the current browser tab. Mingmist does not receive the content unless you independently share the result elsewhere.
Limitations
If PDF.js cannot open the document at all, the browser version cannot rebuild cross-reference structures or deeply repair objects. Output does not preserve original text or interactive structures.
FAQ
Can it repair every damaged PDF?
No. Only content PDF.js can still parse and render can be recovered; missing or truncated data cannot be restored.
Why is the output image-based?
Raster rebuilding avoids many damaged objects and structures, at the cost of text, links, forms, and other interactive information.
