About this tool
Sideways pages come from the obvious places: a phone held in landscape for a long table, a flatbed scanner fed a sheet the wrong way, a shop that scanned your documents in a hurry. The content is fine. It is the orientation that makes an official at the other end squint, or an upload preview look wrong.
Every PDF page carries a rotation value, and this tool adds your angle to whatever that page already says. That sounds like a technical detail and it is the whole point: if a page shows up sideways on screen and you choose 90, it turns 90 degrees from where you see it, not from some hidden starting position. You never have to guess what the scanner wrote into the file.
Leaving the Pages box empty turns the entire document, which suits a scan
where every sheet went in the same way. Naming pages, as in 2,4,6-8,
touches only those and leaves the rest alone — useful for a mixed document
where a couple of landscape tables sit among ordinary portrait pages. Two
runs cover a file that needs two different angles.
Nothing is re-drawn, so the file that comes out is the file that went in, turned. Text stays selectable, scans keep their detail, and the size hardly changes. The whole operation happens in your browser, on your own device, so a document you would not email to a stranger does not have to be uploaded to one either.
How to use this tool
- Choose your PDF. Pick one PDF, or drag it onto the box. Files up to 50 MB are fine.
- Pick the angle. Rotate clockwise by 90, 180 or 270 degrees. A page lying on its side usually needs 90 or 270; a page that is upside down needs 180. 270 clockwise is the same as a quarter turn anticlockwise.
- Say which pages. Leave the Pages box empty to turn the whole document. To turn only some, write them as 1-3,5 — the same numbering the PDF uses, where the first sheet is page 1.
- Run and download. The result saves with -rotated added to the original filename. Open it and look at the pages before you upload it anywhere.
What this tool does not do
- Only 90, 180 and 270 degrees. It cannot straighten a scan that is a few degrees crooked.
- One angle per run. Pages needing different angles take separate runs.
- It cannot open password-protected or encrypted PDFs.
- It does not crop, resize or reorder pages, and it does not change page size.
- There is no on-screen preview of the pages. Open the download to confirm the result.
- Complex fonts, forms, annotations and unusual PDF structures may not survive editing perfectly.
Common questions
The page was already sideways. Will rotating it make things worse?
No. The angle you choose is added to the rotation the page already declares, so the page turns by exactly the amount you asked for from how it looks now on screen. You do not have to work out what the file was doing before.
Some pages need one angle and some need another.
Run the tool twice. First list the pages that need 90 and run it, then feed the downloaded file back in, list the pages that need 270, and run it again. Each run only touches the pages you name.
Does rotating reduce quality or make the file bigger?
Neither. Rotation is recorded as a property of the page rather than by redrawing anything, so scans keep their resolution, text stays selectable and the file size barely moves.
My scan is crooked by a few degrees. Can this fix it?
No. Only quarter turns are available: 90, 180 and 270. Straightening a slightly tilted scan needs a different kind of tool, or a rescan.
It says the PDF could not be opened.
Password-protected and encrypted PDFs are not supported, and the same message appears for a damaged file. Save an unprotected copy from an app that can open it, then rotate that.
Why does the page still look wrong in one app but right in another?
Some viewers ignore the rotation flag a PDF sets, and some phone gallery apps show a cached thumbnail from before the change. Open the downloaded file in a proper PDF reader before you decide it did not work.
