1Upload the PDF documents that came out the wrong way round.
2Pick a turn of 90, 180 or 270 degrees.
3Apply the rotation; the pixels and the orientation flag are reconciled so every viewer agrees on which way is up.

Rotate PDF FAQ
Can I rotate a whole batch in one go?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
How does Rotate PDF turn the file?
+
Concretely, the page rotation attribute is set in the page dictionary rather than the content being redrawn, so the operation is instant, lossless and reversible, and text stays selectable at the new orientation. Quarter turns and half turns are the common case and take the cheapest path available for the format.
Anything specific to PDF I should know?
+
Yes — a PDF is an object graph, not a page image, so text stays selectable and vectors stay sharp no matter what happens to the raster content inside it. It is the kind of thing that explains why a file looks right in one application and wrong in another.
What can I upload to Rotate PDF?
+
Any standard PDF, including ones produced by a scanner, by a word processor or by a print driver. Files with an owner password that only restricts editing are handled; files that need a user password to open are not, and we do not attempt to break encryption.
Is there a file size limit on Rotate PDF?
+
Yes: free use has a size limit per document, and the page tells you when a file is over it; Ghostscript and qpdf do the work. Scanned PDFs are the usual thing that exceeds it, and compressing the document first is normally enough to bring it back under.
Will Rotate PDF lower the quality of my PDF documents?
+
Text and vector artwork are objects rather than pixels, so they stay perfectly sharp at any zoom no matter what happens. Only the embedded raster images can degrade, and only if the operation you chose resamples them.
Can I run Rotate PDF on several PDF documents at once?
+
Yes — upload the set and they process in parallel under one set of settings, which is the point of doing a document workflow here rather than clicking through a desktop reader.
Why does a EPUB site host Rotate PDF?
+
EPUB.to is built around the open eBook format — XHTML in a zip, reflowable by design, and readable on hardware nobody has thought about the layout for. A book is a zip full of markup, images and fonts, so almost every job people bring to an eBook site is really a job on one of those things. Rotate PDF runs on the same upload and the same account as the conversions because that is where it is needed.
What should I do with the result once Rotate PDF is finished?
+
The converter on this site moves books between EPUB, MOBI, AZW3, PDF and DOCX, so a title ends up on whatever hardware is actually going to read it. Doing that after Rotate PDF means the conversion is made from the version you settled on, not from the one you were still fixing.
Is Rotate PDF here the same tool the sibling sites run?
+
The engines are shared — the same toolchain, the same workers, the same limits. What a EPUB site adds is a view on reflow: which of these operations a reflowable book genuinely supports, and which ones only make sense on the fixed-layout media inside it. It also starts from one fact about the format this site is named after: the book is a zip of XHTML with a manifest, so the text costs almost nothing and every decision that matters is about the embedded images and font subsets.
Do I need an account, and does anything get kept?
+
No account is needed. Uploads and results are kept for about 24 hours, which leaves time to download the result, and are then deleted automatically; nobody reads, lists or indexes them. Several files in one job need a paid plan.
