## FAQ

### How does deskew detection work?

The tool analyzes text line angles to detect skew and applies precise rotation to straighten each page.

### Does this preserve bookmarks and form fields?

Yes. Each page rotates around its center; bookmarks and form fields keep their target positions on the deskewed page.

### What PDF versions are supported?

PDF 1.0 through 2.0. Encrypted files require unlocking first; PDF/A inputs come out as PDF/A.
