FAQ

Can I rotate only selected pages?

Yes. Pass a pages array to rotate only specific pages, or use all pages when your workflow requires it.

Does rotation change file quality?

Rotation updates page orientation without rasterizing normal PDF content.

How are Credits charged?

Each successful Rotate PDF API request uses 1 Credit.
