## How to use it
1. **Add the PDF.** Drop one or more PDFs onto Rotate PDF Pages.
2. **Choose the turn.** In the right-hand panel, set Turn to 90° right, 90° left, 180°, Flip horizontally or Flip vertically.
3. **Pick the pages.** Leave Pages blank for every page, or type the ones to change, like 2, 5-7.
4. **Click Rotate.** A corrected copy is saved in a dated folder in Downloads › OneMacTools, ending in “rotated” or, for flips, “flipped”.

## Options
- **Turn:** 90° right turns pages clockwise, 90° left anticlockwise, and 180° turns them upside down. Flip horizontally and Flip vertically mirror the page, which suits scans made through glass or from a mirrored print.
- **Pages:** Leave blank to change every page, or type page numbers and ranges like 2, 5-7 or 10- to change only those.

## Tips
- Look at the thumbnails in Preview first and note which pages are sideways, so you can fix only those and leave the rest alone.
- Turning by 90° or 180° only changes the page's orientation setting, so text, links and quality stay exactly as they were.
- Flipping redraws the page as a mirror image. Use it only for pages that really are mirrored, as normal text would come out backwards.
- If some pages need 90° right and others 90° left, run the tool twice: once for each set, using the copy from the first run.

## Questions
**How do I rotate a PDF and save it on a Mac?**
Drop the PDF onto Rotate PDF Pages, choose 90° right, 90° left or 180°, and click Rotate. The turned pages are saved in a new PDF, so they open the right way up everywhere.

**How do I rotate just one page?**
Type its number in Pages, like 4, and only that page turns. Leave Pages blank to turn every page.

**Does rotating lower the quality?**
No. A 90° or 180° turn only changes how the page is oriented; the content isn't redrawn.

**How do I fix a mirrored scan?**
Choose Flip horizontally for left-to-right mirroring, or Flip vertically for top-to-bottom, and the page is redrawn the right way round.

**Can I rotate pages in several PDFs at once?**
Yes. Drop them all; the same turn and page selection is applied to each one.
