How it works

Rotate PDF in three moves.

No app to open, no window to find. It happens where the file already is.

  1. Drag

    Start dragging the file from Finder, Mail, Photos or your desktop.

  2. Pause

    Hold still for a moment. Sheaf’s actions open in a circle around your cursor.

  3. Let go on Straighten

    Sideways pages turn upright; tilted scans are levelled. A fixed copy appears.

Your options on a Mac

Three ways to do it, honestly compared.

Preview (built in)

Select pages in the sidebar, press Cmd-R, save.

  • Free and built in
  • You find and rotate each page
  • Can’t straighten a tilted scan

Online PDF sites

Upload the file to a website, wait, download the result.

  • Your document goes to someone else’s server
  • Free plans limit files, size or tasks per day
  • Needs an internet connection

SheafFastest

Drag the file, pause, let go.

  • Finds sideways pages for you
  • Levels slightly crooked scans
  • Fixed copy saved, original kept

Rotate a few pages by hand

For exact control, choose Organize: you see every page and can rotate any of them by 90°, reorder or delete pages, then save one file.

Then make it searchable

Upright, level pages give much better text recognition. After straightening a scan, make it searchable.
