## FAQ

### Are scanned PDFs uploaded?

No. Rendering, cleanup, recompression, and export run in your browser.

### Will text stay selectable?

Scanned pages are rebuilt as optimized images. Use OCR PDF next when you need searchable text.

### Does this deskew pages?

This optimizer handles contrast, grayscale or black-and-white conversion, crop, speckle cleanup, and recompression. Dedicated Deskew PDF is a separate scan tool.
