If your PDF pages are upside down — a common result of scanning from the wrong end or exporting from certain apps — rotating 180 degrees fixes them in seconds. Here is how to do it for free.
A 180° rotation is needed when the content is fully upside down — text reads from bottom to top and images appear inverted. This usually happens with double-sided scans where the bottom pages are captured in the wrong orientation.
Go to pdfeditor.onl/rotate-pdf. Upload your PDF. Page thumbnails will show the current (upside-down) orientation.
Click the rotate-right button twice on any page to rotate it 180°, or click rotate-left twice. Both paths arrive at 180°. Use Rotate All to flip every page at once if the whole document is upside down.
Tip: Two clicks of 90° = one 180° rotation. The thumbnail updates after each click so you can see the progress.
Click Download PDF and open the file. All rotated pages should now read normally. If any page was already correct and got rotated by accident, re-upload and adjust only the affected pages.
180° rotation turns content upside down (or right-side up if it was upside down). It is a rotation, not a mirror flip — the left-right orientation is unchanged.
Yes — before downloading, you can click rotate again to reverse. Once downloaded, keep a backup copy of the original if you need to revert.
