How to rotate a PDF page on iPhone

On iOS 26, open the PDF in Preview, use the page-rotation controls, then save the file. Apple documents Rotate Left and Rotate Right in Preview. You do not need a separate app for this workflow.

  1. Open the PDF in Preview and select the page that needs correcting.
  2. Use the More menu or page-thumbnail actions to rotate left or right. Repeat a quarter turn for an upside-down page.
  3. Review the other pages. Leave correctly oriented portrait and landscape pages as they are.
  4. Save the changes and reopen the PDF. If you need to keep the original, duplicate the file before editing.

Apple’s Preview save and duplicate guide explains how to retain a separate copy. Controls differ on earlier iOS versions.

Rotate a scanned page in ScanLens

  1. Open the document and choose the page that is sideways or upside down. Save a full copy first if you need the current version.
  2. Open the page adjustment tools and use the left or right quarter-turn control.
  3. Check the crop and text orientation, then save the page adjustment. Repeat for other affected pages.
  4. Export the corrected PDF and reopen it from Files or the attachment preview.

This is page adjustment, not a promise of lossless PDF-object editing or unchanged file size. Check small text, diagrams, and annotations in the export.

Sideways pages, mixed orientation, and tilted scans

Sideways or upside down: use one or two quarter turns until the text reads upright. Check the actual page content rather than trying to make every thumbnail portrait.

Mixed portrait and landscape: rotate only incorrect pages. A landscape table may already be correct; forcing it into portrait can make it harder to read.

A slight tilt: a 90° turn does not straighten a crooked scan. Adjust the scan’s corners or capture the page again. See scan quality adjustments and PDF cropping.

Frequently Asked Questions

Can I rotate a PDF on iPhone without downloading an app?

Yes. Preview on iOS 26 has PDF page-rotation controls. Open the PDF, rotate the affected page, save the file, and reopen it to check.

How do I rotate just one page in a PDF?

Select the affected page or thumbnail before rotating. Review the neighboring pages after saving so correctly oriented pages stay unchanged.

How do I turn an upside-down PDF page upright?

Apply two quarter turns in the same direction, then save and reopen the PDF. Check that the text and any form fields face the right way.

Why does the PDF look sideways again after I share it?

Check that you used a page-editing control and saved the change. Reopen the file you actually attached; changing the reading view or attaching the original can leave the recipient with the old orientation.

Does rotating a PDF guarantee unchanged quality and file size?

No. The result depends on the app and export settings. Check small text, images, annotations, and page dimensions in the exported PDF instead of assuming it is byte-identical to the source.

Can a quarter turn fix a slightly crooked scan?

No. A quarter turn corrects sideways orientation, not a small tilt. Adjust the scan boundary or recapture the page for a straighter result.
