# Deskew scans to PDF — straighten crooked images, no upload

> Correct skewed scan images with a rotation and rebuild them as a PDF in your browser. Pairs with images-to-PDF. Nothing is uploaded.

Queue crooked PNG or JPEG scans, apply a rotation correction, and rebuild them as a straightened PDF. The correction is applied on your device, so nothing is uploaded.

Scans photographed or fed in at an angle look unprofessional and read poorly. Deskew straightens those images and packages them into a clean PDF, pairing naturally with an images-to-PDF workflow.

For already-flat photos you just want as a PDF, use Images to PDF; to rotate pages inside an existing PDF, use Organize.

## How to

1. **Add scan images.** Queue the PNG/JPEG scans that came out crooked.
2. **Correct the angle.** Apply a rotation to straighten each image.
3. **Export PDF.** Rebuild the straightened images into a PDF.

## FAQ

### What files does it take?

PNG and JPEG scan images, which it straightens and assembles into a PDF.

### How is this different from Organize's rotate?

This corrects skewed scan images and builds a PDF from them, whereas Organize rotates pages in an existing PDF in 90° steps.

### Are my scans uploaded?

No. Rotation and PDF assembly happen in the browser, so the images stay on your device.
