I have a PDF on Google Docs, but the image is sideways. I would like to rotate the document so it can be read, but I don't want to install any PDF editing software.
Is there an easy way to do this?
Google Docs doesn't support it, but there is Rotate PDF which is a free online service.
Here is a solution which doesn't require any other software or services outside of Google Drive:
Open PDF in the Google Drive viewer
Click on the Print button (or Ctrl + p)
Click on the Cancel button (or Esc)
Right click on the PDF and choose Rotate Clockwise or Rotate Counterclockwise

There's a free online PDF editor called PDFescape that will let you upload, rotate, and save PDFs.
