## What does this tool do?

Turns pages in a PDF a quarter turn at a time, clockwise or anticlockwise, or 180° to flip a page
that was scanned upside down. You choose which pages with the same syntax the other PDF tools use:
`all`, `3`, `2-5`, `8-` or `odd`.

## A rotated page is not a changed page

Rotating in a PDF does not repaint anything: it writes a small instruction on the page that says
“show this turned a quarter to the right”. That is why the result is exact, instant, and weighs the
same as the original — and also why some old viewers, which ignore that instruction, will keep
showing the page as it was.

The rotation is **added** to whatever the page already had. If a page came rotated 90° from the
scanner and you turn it another 90°, you get 180° rather than 90°: which is what you meant, and not
what happens when a tool sets the angle from zero.

## Keep in mind

The file never leaves your browser. It is read, turned and written on your own machine, and what you
get is a new file — the original is untouched, so if you rotate the wrong page you have lost
nothing.
