Scanned documents arrive sideways constantly — the scanner's feed orientation rarely matches how the page was printed. Rotating in your PDF viewer only changes how you see it; the file itself is unchanged, so it arrives sideways again for the next person. This writes the rotation into the document.
How to use the Rotate PDF
- Drop a PDF onto the upload area, or click to choose one
- Choose the rotation: 90°, 180° or 270°
- Click specific pages to rotate only those, or select none to rotate the whole document
- Click Rotate and download the result
Viewer rotation versus saved rotation
Most PDF readers have a rotate button that affects the current view only. Close the file and the rotation is gone, because nothing was written.
What this tool changes is the page's /Rotate attribute — a value stored in the document itself, which every conforming reader honours. Once set, the page opens the right way up everywhere: in browsers, in Acrobat, when printed, and when imported into another document.
The attribute only accepts multiples of 90. Arbitrary angles would require re-rendering the page content, which is a fundamentally different and much lossier operation.
Rotating some pages but not others
Mixed orientation within one document is common — a portrait report with a landscape table dropped in the middle, or a scan where only some sheets went through sideways.
Select the specific pages you need to turn and leave the rest alone. The number under each page shows its current rotation, so you can see at a glance which ones are already turned.
Rotation accumulates rather than replaces. A page already at 90° that you rotate another 90° ends at 180°. That is usually what you want, but it is worth knowing if you apply a rotation twice by accident — the fix is to rotate it the rest of the way round rather than trying to undo.
Frequently asked questions
Is the rotation permanent?
Yes. It writes the /Rotate attribute into the document, so every PDF reader opens the page in the new orientation — unlike a viewer's rotate button, which only changes the current view.
Does rotating reduce quality?
No. Rotation is recorded as an attribute; the page content is untouched. There is no re-rendering and therefore no quality loss.
Can I rotate by an angle other than 90°?
No. The PDF specification only allows rotation in multiples of 90. Arbitrary angles would require re-rendering the page as an image, losing text selectability.
Why did my page end up at 180° when I chose 90°?
Rotation adds to what is already there. A page previously at 90° plus another 90° gives 180°. The current rotation is shown under each page number.
Is my file uploaded?
No. Everything happens in your browser, so scanned contracts and personal documents never leave your device.
