Rotate PDF — Permanent
Rotation is saved into the PDF file using pdf-lib. Correct orientation in all viewers.
Rotation written into the file — not just a display preference. Correct in every PDF viewer.
Rotation is saved into the PDF file using pdf-lib. Correct orientation in all viewers.
The PDF format allows a page to store a "Rotate" value in its page dictionary — a number (0, 90, 180, or 270) that specifies how the page should be displayed. When a PDF viewer rotates a page "for display only," it doesn't modify this value in the file. It just applies the rotation in memory for your current viewing session.
The result: when you email the file and someone else opens it, their viewer reads the original (unmodified) Rotate value and shows the page at the wrong orientation again. The rotation didn't actually save — it was only a display preference in your viewer.
How PDFree makes rotation permanent: PDFree uses pdf-lib to open the PDF and programmatically set the Rotate key on each target page's dictionary. The output is a new PDF with the rotation value baked in. When anyone opens the file in any PDF viewer, the viewer reads the Rotate value and displays the page at the correct angle — automatically, without any manual adjustment.

Yes. PDFree writes the rotation into the PDF file structure using pdf-lib. The output PDF will display at the correct orientation in every PDF viewer — no manual rotation needed by recipients.
Many viewers rotate display-only, without modifying the file. PDFree modifies the actual Rotate key in the PDF page dictionary, so the rotation is part of the file — not just a viewing preference.
