# Auto-Rotate Scanned PDF

> Fix clearly sideways scanned PDF pages locally with best-effort content orientation detection, optional crop, and before-and-after preview.

Canonical: https://helpers.aibrush.co/en/auto-rotate-scanned-pdf

## Options

Best-effort local orientation detection for clearly sideways scanned page content.

Uncertain pages are left unchanged rather than guessed.

Optional crop trims borders after 90-degree rotation when page edges are clear.

Output is rebuilt as page images; run OCR PDF afterward when you need searchable text.

## How to auto-rotate a scanned PDF

1. **Upload PDF** — Upload a scanned PDF with sideways pages.
2. **Choose output** — Choose color, grayscale, or black-and-white output.
3. **Adjust settings** — Adjust quality, DPI, mild contrast, and border crop.
4. **Auto-rotate** — Auto-rotate locally, compare the preview, and download the corrected copy.

## FAQ

### Are PDFs uploaded?

No. Rendering, orientation detection, preview, and export run in your browser.

### Will uncertain pages rotate?

No. The tool rotates only confident sideways pages to avoid making correct pages worse.

### Can it fix small tilt?

Use Deskew PDF for small angle correction. Auto-Rotate Scanned PDF focuses on 90-degree sideways pages.
