1. What Is PDF Repair?
Repair PDF is the process of fixing a PDF file that will not open or shows errors. Imagine your comic book got wet and pages stuck together; Repair PDF is like gently drying and flattening those pages so you can read again. It restores text, images, bookmarks, and page structure.
2. Why Do PDFs Break?
| Cause | Real‑World Example |
|---|---|
| Interrupted download | Wi‑Fi drops while downloading a 30 MB e‑book. |
| Bad storage | USB stick unplugged mid‑save corrupts file. |
| Faulty OCR scan | Scanner glitch saves half pages. |
| Virus / Malware | Malicious code injects invalid objects. |
| App crash | PDF editor froze during save; structure incomplete. |
Corrupted PDFs might show errors like “There was an error opening this document” or blank pages.
