How to rotate PDF pages and save them
Fix sideways or upside-down pages in a PDF and save them that way for good.
Most of the confusion around rotating PDFs comes from one thing: there are two kinds of rotation. When you rotate a page in a PDF reader, you're usually only changing your own view, and it often isn't saved. When you rotate with an editing tool, the new direction is saved into the page, so every reader and every printer shows it the right way.
This matters most with scans. One sheet fed in the wrong way round gives you a page that everyone after you has to tilt their head to read.
Rotating doesn't cost you any quality. Each PDF page has a setting for 0, 90, 180 or 270 degrees, and changing it only changes which way the page is shown. Nothing is redrawn or compressed, so there's no reason to live with a sideways page.
One thing rotation can't do is straighten a slightly crooked scan. Rotation turns the whole page in quarter turns. If the page went through the scanner a few degrees off, the content is crooked inside an upright page, and you need a straightening (deskew) tool for that.
If the file is going to be merged with others, fix the rotation first. It's much easier to fix one short document than to hunt for sideways pages in a 200-page bundle.
When you might need this
- Some pages were scanned sideways or upside down.
- You don't want every reader to rotate the pages themselves.
- A document mixes portrait and landscape pages and needs tidying.
- You want it to print the right way up.
- You're about to merge it into a bigger bundle.
How to do it
- Open Rotate PDF.
- Choose the PDF with the wrong-way-round pages.
- Rotate the pages that need it, left or right, using the page previews.
- Leave the correct pages alone.
- Save the file, then open the saved copy to check the rotation stuck.
Free, with no account. Open it in a new tab and follow along.
Open Rotate PDFTips
- Only rotate the pages that need it. Rotating the whole document usually just moves the problem.
- Look at the previews carefully. Upside-down pages are easy to miss when you're skimming thumbnails.
- Check the saved file, not the one open in your reader. Your reader's rotation might only be temporary.
- Fix rotation before merging so the combined file is right the first time.
- Wide spreadsheets are often meant to be landscape. Look at the content before you rotate, because a wide table turned to portrait gets harder to read, not easier.
- When a scanner feeds every other sheet the wrong way, it's usually a regular pattern. Rotating those pages as a group is faster than going one by one.
- If pages need both rotating and reordering, rotate first. It's easier to judge which way is up while they're still in their original order.
Common mistakes
- Rotating in a PDF reader, closing it, and assuming it saved.
- Rotating every page when only one scanned page was wrong.
- Turning a page 180 degrees when it needed 90 the other way, and not checking again.
- Fixing rotation after merging, then having to find a few sideways pages in a much bigger file.
- Trying to fix a slightly crooked scan with rotation. A page that's three degrees off needs a straightening tool.
- Sending the file without opening the saved copy. That's the only way to be sure the change was saved.
How this compares to Smallpdf, iLovePDF and Adobe
Rotating is one of the simplest things you can do to a PDF, which makes it a good way to see how the free plans work. Smallpdf and iLovePDF will rotate your file, but it counts against the same small daily allowance as a big conversion, and the whole document gets uploaded and downloaded just to change one setting per page.
Adobe can rotate pages online too, once you sign in.
Doing it in your browser means no upload and no allowance used up. Rotating here is instant, there's no limit, and the file never leaves your device.
| Criterion | Smallpdf | iLovePDF | Adobe Acrobat online | Easy File Tools |
|---|---|---|---|---|
| Where your file is processed | On their servers, after you upload it | On their servers, after you upload it | In Adobe's cloud, after you upload it | In your browser, on your own device |
| Account or sign-in | Asked for early, and needed once you pass the free allowance | Optional for small jobs, needed for bigger ones | Most online tools need an Adobe ID | Never needed |
| Usage limits | A few free tasks, then an upgrade prompt | Daily task and file limits on the free plan | The free web tools are mostly a preview of the paid plan | No task counters and no daily limits |
| File size ceiling | The free plan limits upload size | The free plan limits upload size | Cloud upload limits apply | We don't set one. Your device's memory is the practical limit |
| Works without a connection | No, their server does the work | No, their server does the work | No, the cloud does the work | Yes for the browser tools, once the page has loaded |
| Cost | Paid subscription for full access | Paid subscription for full access | Paid Acrobat subscription for full access | Free. Every tool is open to everyone |
Other services change their plans and limits often, so treat this as a rough picture and not a price list. Check their websites for the current details.
Frequently asked questions
- Is rotating in my PDF reader permanent?
- Not always. Many readers only turn the view while the file is open. Saving with a rotate tool writes the change into the file itself.
- Can I rotate just some pages?
- Yes. Rotate only the pages that need it and leave the rest.
- Does rotating lower the quality?
- No. Rotation is a setting on the page. Nothing is redrawn or compressed.
- Will the rotation still be there when I print?
- Yes, once it's saved in the file. That's the difference between saving the rotation and only turning the view.
- Can I straighten a crooked scan?
- Not with this tool. It turns whole pages in quarter turns. A scan that's a few degrees off needs a straightening (deskew) tool or a scanner app.
