How to Rotate a Scanned PDF and Save It That Way
You scanned a document and half the pages are sideways. You rotated them in your viewer, sent the file, and the recipient got them sideways again. That's because rotating in a viewer isn't saved in the file. Here's how to rotate so it sticks.
Why scans come out sideways
Scanners and scanning apps guess which way is up from the page shape or the text. The guess fails in a few common situations:
- A landscape table or chart inside a portrait document.
- A page fed into the scanner upside down.
- A phone photo taken while holding the phone sideways.
- Documents with little text, like receipts or certificates.
Rotating the view vs. rotating the file
Acrobat Reader, browsers and your computer's preview app all have a rotate button. In most cases it only changes what you see right now. The file itself doesn't change, and anyone who opens it sees the page sideways. For the change to last, the page has to be rotated in the file.
How to rotate and save
- Open Rotate PDF and upload the file.
- Pick a direction. Text reading bottom to top needs 90° clockwise. Text reading top to bottom needs 90° counter-clockwise. An upside-down page needs 180°.
- If only some pages are sideways, list them in the pages field, like
2,5. If they all are, leave it empty. - Download and open to check.
Different pages, different directions
Sometimes page 2 needs to turn right and page 4 left. Do it in two rounds: rotate page 2, download, upload the result and rotate page 4.
Why it matters beyond looks
- OCR: text recognition on a sideways page gives poor results. Rotate before running OCR.
- Converting to Word: a sideways page lands in the Word document sideways.
- First impressions: a document sent to a bank, an employer or a court with upside-down pages looks careless.
Preventing it next time
When photographing documents with your phone, lock screen rotation and hold the phone upright. With a sheet-fed scanner, insert all pages the same way, usually top edge first. The guide to scanning with your phone covers shooting technique.
