How do I rotate a PDF page permanently for free?

Upload your PDF to AlteredIdea Page Rotation, select the rotation angle, choose which pages to rotate, then click Rotate. Download the new PDF with the rotation permanently applied.

Can I rotate only specific pages in a PDF?

Yes. Choose 'Specific Pages' mode and enter the page numbers or ranges you want to rotate (e.g. '1,3,5-7').

Will the rotation be permanent in the saved PDF?

Yes. The rotation is embedded in the PDF page metadata, so it will appear correctly in all PDF viewers.

Why is my PDF showing sideways or upside down?

This commonly happens with scanned documents where the page rotation flag was not set correctly during scanning. AlteredIdea's rotation tool fixes this by updating the page rotation in the PDF structure.

Can I rotate by 180 degrees?

Yes. Select 180° to flip pages upside-down (or right them if they were inverted).

Are my files uploaded to a server?

No. All rotation is done locally in your browser. Your files never leave your device.

What is the difference between 90°, 180°, and 270° rotation?

90° rotates clockwise once. 180° flips the page completely. 270° rotates clockwise three times (equivalent to 90° counter-clockwise).

Can I undo a rotation after saving?

Not in the same session, but you can run the tool again and rotate by 90° or 270° in the opposite direction to undo.

Does rotation reduce PDF quality?

No. Page rotation only updates a metadata flag in the PDF: it does not re-render or re-encode any content.

Can I rotate pages in a scanned PDF?

Yes. Scanned PDFs are treated the same as any other PDF: the rotation flag is updated without touching the scan image data.

How to rotate PDF pages online for free: fix upside-down scans instantly

AlteredIdea's Page Rotation tool corrects the orientation of PDF pages by updating the rotation flag in the PDF metadata. This is the proper way to fix a sideways or inverted PDF: unlike screen-rotation workarounds, the fix is embedded permanently into the document so every viewer renders it correctly.

You can rotate all pages at once, or target specific pages by entering page numbers or ranges. This is useful when only certain pages of a scanned document came out sideways, or when you need to rotate landscape pages in an otherwise portrait document. Processing happens entirely in your browser: no files are uploaded anywhere.
