## What this tool does
Scan a document, drop the blank pages automatically — keep every page that matters, in order.

## Typical user problems
- Scanned applications and certificates are full of accidental blank pages. Portals flag them, printers waste them, reviewers get annoyed. You need the blanks gone without losing a single content page.
- ADF scanners insert blank pages whenever the feeder double-feeds or the sheet backs are empty. Submission systems reject documents full of blanks — you need them stripped automatically, in order.
