The sideways contract
You've just received a signed contract from a client. They scanned it at the office, emailed it over, and every single page came through rotated 90 degrees. You need to forward it to your legal team in the next ten minutes — there's no time to ask the client to resend it.
You open the PDF rotator, drop in the file, and see all the pages laid out as thumbnails. One click on "Rotate all right" and every page flips into the correct orientation. You check the thumbnails, everything looks right, and you click "Rotate PDF."
The corrected file downloads in seconds. You forward it, and no one on your legal team ever knows there was a problem. Fifteen minutes later, you've already moved on to the next item on your list.
No sign-up, no waiting for a server, no size limit headaches — just a fixed PDF when you needed one.
