Rotate PDF

Rotating a PDF turns its pages so they display the right way up. Scans and phone captures often come out sideways, and a quarter turn fixes them for every reader rather than leaving each one to tilt their head. Choose 90, 180 or 270 degrees and the rotation is written into the file itself, as an instruction each page carries. The page content is not redrawn: text stays selectable, images are not re-compressed, and what comes back is the same document seen from a different angle. It runs in your browser, so the document stays on your device.

How to use it

1. Add the PDF you want to turn.
2. Pick how far to rotate: 90 degrees for a sideways scan, 180 for upside down.
3. Rotate, then download the corrected file.
4. Running it twice adds up — 90 degrees on a page already turned 90 leaves it at 180 — so an over-rotation is undone by completing the circle.

Examples

• A sideways scan becomes upright with a single 90 degree turn.
• A page rotated 90 degrees twice ends up at 180.
• A page already carrying 180 degrees, turned another 270, ends at 90 — the total wraps around a full turn.
• A 40-page scan comes back with every page turned by the same amount, and the result note confirms the count.

Frequently asked questions

Does rotating change the file permanently?

Yes, in the way that matters: the rotation is saved into the document, so every viewer opens it the right way up and it survives being emailed, printed or uploaded. What it does not do is redraw the page. A PDF page carries a rotation instruction alongside its content, and this tool changes that instruction rather than re-rendering anything — which is why text stays selectable, scanned images are not re-compressed, and the file is no worse in quality than it started. Turning the view inside a reader is a third thing again: that changes only your screen, and it is forgotten when you close the file.

Why does my PDF open sideways?

There are two different sideways and they behave differently. In the first, the page is upright but carries a rotation instruction of 90 or 270 degrees; a conformant viewer honours it, while a tool that ignores it — some built-in browser viewers, some print pipelines, some image extractors — shows the page unrotated, which is why the same file can look right in one application and wrong in another. In the second, nothing is rotated at all: the scanner recorded a sideways picture and placed it on an upright page, so the instruction reads zero and every viewer agrees. This tool adds a turn to whatever the page already carried, which fixes both — but it also means a file that only looked wrong in one viewer will now look wrong in the other.

Can I rotate only some pages?

Not yet — this turns every page by the same amount. To fix a single page, split it out first, rotate it, then merge the pages back together. Per-page rotation is on the roadmap.

Are my files uploaded?

No. Rotation happens inside your browser and the document never leaves your device, which matters for the scanned personal paperwork that most often needs straightening.

Will rotating change the file size or quality?

Not the quality, and barely the size. The rotation is one number stored per page, so nothing is re-encoded and no pixels are touched. The saved file can differ a little from the original because it is written out fresh — objects are renumbered and unused ones dropped — but the page content itself is unchanged. That is the practical difference between rotating a PDF and rotating an image: one is an instruction, the other is a re-render.

Why is my page still sideways after rotating it?

Usually because it went the wrong way: 90 and 270 are indistinguishable in a file listing and opposite on screen, so try the other one. If a 90 degree turn left it upside down, the page began at 180 and the two rotations added — this tool turns by the amount you pick on top of whatever the page already carried, rather than setting an absolute angle. And if the whole document turned when you wanted one page, that is expected: every page gets the same amount, so split the odd page out, turn it alone, and merge it back.

Can I rotate the scanned image rather than the page?

No, and the distinction is worth knowing. Page rotation applies to everything on the page at once; there is no way to turn one image and leave the rest in place. When a scan has the picture sideways on an upright page, rotating the page turns the picture upright too, which is normally what you wanted. If the image itself has to be corrected — because something else on the page must stay put — export the pages with a PDF-to-JPG tool, fix them in an image editor, and rebuild the document with images-to-PDF.
