Rotating pages in our React Native PDF viewer

Markdown version of this page, suitable for AI agents and automation

You can rotate individual pages in the viewer by calling PDFDocument.setRotationOffset. This sets a display-only rotation for the specified page — it’s applied in the viewer, but it isn’t written back to the PDF.

Setting a page’s rotation

Call setRotationOffset(pageIndex, rotation) on the document instance returned by getDocument():

await this.pdfRef.current?.getDocument().setRotationOffset(0, 90);
  • pageIndex: Zero-based page index of the page to rotate.
  • rotation: Rotation in degrees. Must be 0, 90, 180, or 270.

Resetting a page’s rotation

To reset a rotated page back to its original orientation, set its rotation offset to 0:

await this.pdfRef.current?.getDocument().setRotationOffset(0, 0);
