Attempt to fix a corrupt PDF by re-parsing and rebuilding its file structure.
Broken cross-reference tables, truncated file endings, junk appended after the PDF data, and some invalid objects — the most common reasons a PDF “won’t open”. If the page data itself is destroyed, browser-side repair can’t reinvent it, and we say so.
It’s the last-resort strategy: if the structure is unrecoverable but the pages can still be rendered, we rebuild the document from images of them. The result opens and prints normally, but text is no longer selectable.
