Does Preview rotate all pages at once or only selected pages?

By default, rotation applies only to the pages you have selected. To rotate all pages, enable thumbnails (Option+Command+2), then press Command+A to select all pages before using Command+R or Command+L.

How do I undo a rotation after I have saved?

Go to File > Revert To and pick a previous version from the list. This will discard all changes after that version, including the rotation.

Why does my rotated PDF still appear upside down in another program?

Some programs ignore Preview's rotation metadata. Save a copy of the file with File > Save As, or use the site's Rotate PDF tool to create a new file with the rotation embedded.

Can I rotate only one page in a multi-page PDF without affecting the others?

Yes. Open the thumbnails sidebar (Option+Command+2), click the thumbnail of the page you want to rotate, then press Command+R or Command+L. Only that page will rotate.

Rotate PDF Pages on Mac in Preview (and Make It Stick)

To turn a rotate pdf mac page and make the change stick, use Preview. It is already on your Mac. Open the PDF, then go to Tools > Rotate Left (Command+L) or Tools > Rotate Right (Command+R). Press Command+S to save. Preview also writes edits straight into the file, so you do not need to remember every time. What follows covers shortcuts, selecting specific pages, and how to reverse a turn if you change your mind.

Rotate a PDF in Preview with Keyboard Shortcuts

Rotate Left (Command+L): Spins the page 90 degrees counterclockwise.
Rotate Right (Command+R): Spins the page 90 degrees clockwise.

Each press turns the selected page by another 90 degrees. Scanned documents and uploaded files often arrive upside down. To fix one, press Command+R twice or Command+L twice.

Preview Rotate Selected Pages Vs. All Pages

By default, the turn applies only to the pages you have selected. To turn every page, select them all first.

Selecting Pages in the Thumbnails Sidebar

Enable thumbnails by going to View > Thumbnails (shortcut: Option+Command+2). A sidebar appears showing small previews of each page.

Select a single page: Click its thumbnail.
Select multiple pages: Hold Command and click each thumbnail, or click the first page, hold Shift, and click the last page to select a range.
Select all pages: Click any thumbnail, then press Command+A (or choose Edit > Select All).

After selecting the pages you want, use Command+R or Command+L. Unselected pages stay as they were. This is useful when only one or two pages in a multi-page document are oriented incorrectly.

How to Save the Rotated PDF on Mac

Once you have turned the pages, save the file. That locks the orientation.

Choose File > Save or press Command+S.
Preview autosaves edits to the file as you work. Even if you close the document without saving manually, the turn is kept.

Because Preview writes changes straight into the file, you do not need to worry about losing your work. The turned PDF opens correctly next time.

Reverting a Turn in Preview

If you turn a page and then want the original orientation back, Preview includes a revert feature.

Go to File > Revert To and choose a previous version from the list. Preview keeps a history of saved versions. Reverting discards all changes made after that version, including any turns. You can also use the Undo command (Command+Z) immediately after a turn if you have not saved yet. Revert To works even after saving.

When Preview Rotation Does Not Stick

Sometimes a turned PDF appears to snap back to its original orientation when you open it in another program. This happens when the program ignores Preview's rotation metadata. To make the turn stick everywhere, save a copy of the file after turning.

Force a New File That Holds the Turn

Open the PDF in Preview, turn the pages you need, then choose File > Save As to create a new file. The new file has the orientation baked into its page data, so most PDF readers honour it. If you still see the original orientation, try the Rotate PDF tool, which turns every page 90 degrees clockwise and saves a new file named <original-name>-rotated.pdf.
