Honest limit: Repair re-saves the PDF with a rebuilt structure, which fixes many common problems (broken cross-reference tables, bad metadata, minor truncation). It cannot fix severely corrupted files — if the page content itself is destroyed or the file is mostly missing, no tool can recover it; re-export from the original app instead.
