Rotate PDF fixes page orientation — for an entire document or individual pages — in 90-degree increments, which is exactly how most scanning and photo-to-PDF conversions end up sideways or upside down in the first place. A single flatbed scanner misfeed, or a photo taken in the wrong orientation before converting to PDF, is usually all it takes to end up with a document that reads correctly on paper but displays sideways on screen.
How to use Rotate PDF
- Choose your privacy mode, then select a single PDF.
- Pick the rotation angle: 90°, 180°, or 270° clockwise, using the angle selector.
- The rotation applies to every page in the document — targeting only specific pages isn't available yet, so a document with a mix of correct and incorrect page orientations needs those pages separated out first (with Split PDF) before rotating just the affected pages.
- Click Process. Only the pages you specified are rotated — everything else in the document, including page order, text, images, and annotations, stays exactly as it was.
- Download the corrected file. The rotation is applied by updating each page's orientation metadata, the same field every PDF viewer already reads to decide how to display a page.
Worked example
Fixing a document scanned in landscape by mistake
A common case: a multi-page document was fed through a scanner sideways, so every page opens rotated 90 degrees from how it should read. Pick a 270° rotation (or 90°, depending on which way it's turned — download and check the result, and if the direction was wrong, re-run with the opposite angle) and every page comes out right-side up. Because the rotation is applied to the whole document at once, a batch where only a few pages are affected — say, 2 pages out of 20 scanned upside down while the rest are correct — needs a different approach: use Split PDF first to pull out just the affected pages, rotate that smaller file, then use Merge PDF to put the corrected pages back with the rest in the right order.

Frequently asked questions
Can I rotate just one page in a multi-page document?
Not directly yet — rotation currently applies to every page in the document in one pass. To rotate only specific pages, use Split PDF first to extract just those pages into their own file, rotate that smaller file, then use Merge PDF to combine the corrected pages back with the rest.
What rotation angles are available?
90°, 180°, and 270°, all clockwise. There is no free-angle or fine-tuned rotation — PDF page rotation is inherently a 90-degree-increment operation.
Does rotating a page change its content or just how it displays?
It sets the page's rotation metadata, the same mechanism PDF viewers use to determine display orientation. The underlying page content is untouched; only how it's presented when opened is affected.
Can I rotate different pages by different amounts in one pass?
Not currently — one rotation angle applies to the whole document per run. For a document needing different angles on different pages, split it into the relevant sections first, rotate each separately, then merge them back together.
Will rotating affect the page size shown in other tools?
PDF viewers and other tools respect the rotation metadata, so a page rotated 90° will display with its width and height effectively swapped, exactly as intended — this is standard PDF behavior, not an artifact of this tool.
I rotated by 90° but it looks upside down instead of right-side up — what happened?
Rotation direction depends on which way the page was originally sideways. If 90° clockwise overshoots or undershoots the correction, download the result to check it, then re-run with 270° (90° counter-clockwise) instead — processing is quick, so trying the other direction costs you little time.
Does rotating a PDF work the same way for scanned pages and pages created digitally (like from Word)?
Yes — rotation is applied via the page's orientation metadata regardless of how the page content was originally created, so it works identically for scanned images, digitally authored text, or any mix of the two within one document.
Can I undo a rotation if I picked the wrong angle?
Re-run the tool on the rotated file with the opposite angle (for example, 180° again to fully reverse a 180° rotation, or 90° to reverse a 270° rotation) — there's no separate "undo," but rotation is fully reversible this way since no content is altered.
Why does PDF rotation only come in 90-degree steps instead of any angle?
This reflects how the PDF format itself represents page orientation — a single rotation value (0, 90, 180, or 270 degrees) applied to the whole page, rather than an arbitrary transform. A genuinely tilted scan (say, 3 degrees off from a crooked feed) needs a different kind of correction — deskewing — which is a distinct operation from fixing gross 90-degree orientation errors and isn't what this tool does.
