How to rotate a PDF
Open the file and each page appears as a preview. The buttons at the top turn the whole document at once; the small pair under each preview turns that one page. Every preview turns as you press, and the angle beside it shows where that page has ended up, so the export holds no surprises.
Fix landscape pages only handles the mixed document, which is the case that makes people give up on other tools. A report where three wide tables were scanned sideways and the other forty pages are upright needs those three turned and nothing else touched. The button finds the pages that are wider than they are tall and rotates just those.
Why a rotation here sticks
A PDF page carries a rotation value of its own, separate from the content drawn on it. Several readers will turn a page on screen for your convenience without ever writing that value into the file — which is why a document can look correct on screen and still come out of the printer sideways, or arrive rotated for the person you sent it to.
This tool writes the value into the document. That is also why rotating costs nothing in quality: not a single glyph or pixel is redrawn, so the output is the same size as the input to within a few bytes.
How the angles work
Turns are relative. Each press adds to whatever the page already carried, and the result is normalised into the four values a PDF is allowed to hold.
| Page was at | Turn right | Turn left | Turn 180° |
|---|---|---|---|
| 0° | 90° | 270° | 180° |
| 90° | 180° | 0° | 270° |
| 180° | 270° | 90° | 0° |
| 270° | 0° | 180° | 90° |
A file straight from a scanner is usually at 0° even when the image on it is sideways, because the scanner wrote the image the way it read it. That is normal and it is exactly what this tool corrects.
If the preview and the page disagree
A very small number of PDFs carry an angle that is not a multiple of ninety, which the format does not really allow and which readers handle differently. Those are rounded to the nearest quarter turn here so the file that comes out is valid everywhere.
Questions
Is my file uploaded to rotate it?
No. The document is opened in your browser, the rotation is written there, and the new file is handed straight back. There is no backend and no copy leaves the device.
Does rotating a PDF reduce its quality?
No, and it cannot. A rotation is stored as a number on the page rather than by redrawing anything, so the text, fonts and images in the file are what they were. The file size barely changes.
Why does my PDF open the right way up but print sideways?
Some readers rotate a page for display without saving that rotation into the file, so the printer receives the original orientation. Rotating here writes the change into the document itself, which is what makes it stick everywhere the file is opened.
Can I rotate just one page?
Yes. Every page has its own pair of turn buttons under its preview, and the preview turns as you press them. The buttons at the top apply to the whole document, or to just the landscape pages when that option is chosen.
What does rotating only landscape pages do?
It turns the pages that are wider than they are tall and leaves the portrait ones alone. That is the usual fix for a scanned report where a few wide tables went through the scanner sideways while the rest of the document is upright.
Are rotations relative or absolute?
Relative. The turn is added to whatever rotation the page already carried, which is why a page that was already at 90° ends at 180° rather than jumping back to 90°. The final value is always normalised to 0, 90, 180 or 270.
