You scanned a 30-page document and 5 pages came out sideways. Chrome's viewer rotates temporarily, but the rotation disappears the moment you close the tab. To save the rotated version, you need a tool that can write the change into the file.

Add to Chrome — FreeWhy Chrome's rotation does not stick
Chrome's built-in PDF viewer has a rotate button (under the print preview), but it rotates the display, not the file. Close the tab and the rotation is gone. Sending the PDF to a colleague — they see it the original way.
To make the rotation permanent, the rotation has to be written into the PDF's page tree as a "/Rotate 90" attribute on each page. That requires a tool that can edit PDF structure.
Method 1: Chrome extension (rotate and save)
The PDF Merge & Split extension supports per-page rotation:
- Open the extension, switch to Rotate mode.
- Drop your PDF. Each page shows as a thumbnail.
- Click the rotate button on any page (or "Rotate all" for batch).
- Click Save and download. Rotation is now permanent.
Method 2: macOS Preview
Preview supports rotation:
- Open the PDF in Preview, show thumbnails.
- Select one or more thumbnails (Cmd+click for multiple).
- Tools → Rotate Left or Rotate Right.
- File → Export As → PDF.
One catch: if you File → Save instead of Export, Preview overwrites the original. Use Export to preserve the source file.
Method 3: qpdf command line
For terminal users:
qpdf input.pdf --rotate=+90:1 output.pdf # rotate page 1 by 90° qpdf input.pdf --rotate=+180 output.pdf # rotate all pages 180° qpdf input.pdf --rotate=+90:3,5,7 output.pdf # rotate pages 3, 5, 7
Useful for batch automation across many files.
Common rotation problems
- Pages rotate but text becomes unsearchable. Caused by tools that re-rasterize the page during rotation. The Chrome extension does not — it sets the /Rotate attribute without touching content.
- Rotation reverts on close. Always means the tool only rotated the view, not the file. Use a tool that writes the change.
- Some pages rotate, others do not. Some PDFs have a mix of "embedded" and "imposed" rotation. The extension handles both transparently.

Frequently Asked Questions
Why does my rotation disappear when I close Chrome?
Chrome's rotate button only changes the display, not the file itself. To save the rotation permanently, use an extension, Preview, qpdf, or another tool that can write the change to the PDF.
Can I rotate just one page?
Yes. Both the Chrome extension and Preview support per-page rotation. Click only the thumbnails you want to rotate.
Does rotation reduce file quality?
No, if done by a tool that sets the /Rotate attribute (extension, Preview, qpdf). Some tools re-rasterize the page during rotation, which does reduce quality and may break searchable text.
How do I rotate a scanned PDF where text is sideways?
Same as any rotation — use Rotate mode in the extension. The OCR text layer rotates with the page automatically and remains searchable.
Can I rotate by 45 degrees?
No. PDF rotation is restricted to 0°, 90°, 180°, and 270° increments by the PDF specification.
