Honestly, no — severe corruption with overwritten data is beyond saving. But many 'broken' PDFs fail on structure alone, and those often recover with most pages intact. It costs you a minute to find out.
The repair keeps every readable page. Content in badly damaged regions may be lost or garbled — that damage already existed in the file; the repair just surfaces what's still there.
Usually one of three things: an incomplete download, a crashed save, or a transfer that corrupted the structure. The index and page tree get out of sync, and readers refuse to open what they can't parse.
No hard limit. Repairing runs locally on your device, so the practical ceiling is your device's memory.
