Good uses
- Check whether a PDF packet is mostly image-only.
- Route failed text extraction toward OCR readiness instead of retrying conversion.

Steps Run order and common questions

- Run the inspection tool locally in your browser.
- Review the scan-report result, then copy or download it if the workbench offers that action.
- Use related retained tools for validation, cleanup, conversion, or the next workflow step.
Use it well Examples, checks, limits, and recovery paths
Bad inputs
- Expecting per-page forensic classification.
- Using it to enhance or clean scans.
- Assuming mixed PDFs have one simple next step.
Output checklist
- Review scan-like and text-layer signals together.
- Check page rotation and image-density reports when OCR is likely.
- Use PDF to Text first when digital text appears usable.
Failure modes
- Mixed digital/scanned PDFs can need manual page review.
- Compressed object streams may hide some signals.
- Scanned classification is heuristic.
Runtime limits
- Browser-local.
- Heuristic scan signal report.
- Does not OCR, repair, or clean the PDF.
