About Rotate PDF
Scanned pages that arrive sideways, a landscape spreadsheet saved into a portrait document, a photo of a whiteboard imported upside down — rotation fixes all of them. This tool turns the pages you choose by 90, 180 or 270 degrees and saves a corrected copy, working entirely inside your browser with a live preview of the first page.
How to use
- Choose or drag in the PDF you want to correct.
- Pick the rotation: 90° for a quarter turn clockwise, 180° to flip, 270° for a quarter turn anticlockwise.
- Apply it to the whole document, or name the pages that need turning.
- Check the preview, then press Rotate and download the corrected file.
Rotation is metadata, not re-rendering
Every PDF page carries a rotation attribute holding one of four values: 0, 90, 180 or 270 degrees. Viewers read it and turn the page before drawing. Rotating a PDF properly means changing that number — the page content is left exactly as it was.
That is why this is instant and lossless even on a 300-page scan. No pixels are resampled, no text is re-flowed, nothing is re-compressed, and the file size barely changes. It also means the rotation is permanent in the file rather than a viewing preference: everyone who opens it sees the corrected orientation.
Rotations add up rather than replace. A page already stored at 90 degrees, rotated by another 90, ends up at 180. This tool applies your choice on top of whatever each page already carries, which is what you want when a document contains a mix of correct and sideways pages.
Rotating only the pages that need it
Mixed documents are the normal case for scans: portrait text pages with the occasional landscape table or diagram. Switch to "Selected pages" and name them the same way as anywhere else — "4, 9-11" turns page four and pages nine through eleven, leaving everything else alone.
The preview shows page one only, so it reflects your setting when page one is in the selection and stays still when it is not. For a long mixed document, work through it in passes: rotate the clockwise-wrong pages by 90, then run the file again for the pages that need 270.
If a page comes out wrong, rotate the saved copy again rather than starting over — three more 90-degree turns bring any page back to where it began.
When rotation is not the fix
A page that looks right on screen but prints sideways usually has a page size problem, not a rotation one — the content is landscape while the page box is portrait. Rotating makes the screen view wrong to fix the print, which is rarely worth it; re-exporting from the source application with the right paper setting is the real fix.
Photographs of documents that are slightly tilted, rather than turned a clean quarter, need deskewing instead. Rotation only works in 90-degree steps because that is all the PDF page attribute can store; anything else has to be applied to the image before it becomes a PDF.
If your viewer has a rotate button, remember that it usually only changes the view for you and is discarded when the file closes. Saving a rotated copy, as here, is what makes the change travel with the document.
Frequently asked questions
Does rotating a PDF reduce its quality?
No. Rotation changes a single attribute on each page rather than redrawing anything, so text, images and file size are untouched.
Can I rotate just one page of a PDF?
Yes. Choose "Selected pages" and type the page number. You can name any mix of pages and ranges, such as "3, 8-10".
Which direction is 90 degrees?
A quarter turn clockwise. Use 270 for a quarter turn anticlockwise, and 180 to flip a page that is upside down.
Why does my page still open sideways in another program?
Some viewers remember a per-user view rotation that overrides the file. Close and reopen the document, or check that you opened the newly downloaded copy rather than the original.
