Rotate PDF pages and save the result permanently
Turn sideways or upside-down pages the right way up and export a document that stays rotated everywhere it is opened.
There are two ways to rotate a PDF and only one of them lasts. Most PDF readers let you spin the view with a toolbar button, which is convenient and completely temporary: it changes what you are looking at, not the file. Close it, send it, print it, and the page is sideways again.
This tool does the other kind. It writes the rotation into the document itself, so the pages come out the right way up for everyone who opens the file afterwards, in any reader, and on any printer.
The operation is lossless — the page is re-oriented, not re-rendered — and it runs entirely in your browser, so the document is never uploaded.
Processed on your device
The rotation is applied inside the browser tab. The document is not uploaded to anything.
Permanent, not a view setting
The rotation is written into the file, so it survives sending, printing and opening in a different reader.
Lossless
Pages are re-oriented rather than redrawn. Text stays selectable and images keep their full resolution.
How to rotate a PDF
Open the PDF and see its pages.
Turn them 90 degrees at a time, in either direction.
The rotation is written into the document.
Download the corrected file.
The document stays on your machine
Rotation is applied by an engine running inside your browser tab. There is no upload step and no server-side copy, which matters as much for a sideways contract as for any other document.
When people reach for this
Fixing a scan that came out sideways
A document fed into the scanner the wrong way round produces pages rotated 90 degrees. Rotating and saving means nobody who receives it has to tilt their head or spin the view themselves.
Correcting landscape tables in a portrait report
Wide tables and charts are often exported rotated so they fit the page. If you want them upright in the final document, this is how you fix it before circulating.
Preparing a document for printing
Print pipelines usually honour the rotation stored in the file and ignore whatever your viewer was showing. Saving the rotation is what makes the printed output match what you see.
Fixing photographed documents
Pages captured with a phone frequently arrive rotated or upside down depending on how the device was held. Correcting them makes the file usable rather than merely present.
What actually happens to your file
A PDF page carries a Rotate entry: a value of 0, 90, 180 or 270 that tells a reader how far to turn the page clockwise before displaying it. Rotating a document properly means changing that number, not touching the content.
When you export, the rotation you chose for each page is serialised into a page map and handed to pdfcpu, compiled to WebAssembly and running in your tab. The engine extracts the pages, reassembles them in order, and applies the requested rotation to each.
Because the underlying drawing instructions are never modified, the operation is completely lossless. The text on a rotated page is still selectable text at the same quality; the images are the same images at the same resolution. Only the page's orientation flag differs.
The rebuilt document is written out and downloaded. Nothing about it — not the pages, not the rotations — is transmitted anywhere.
Where it falls short, honestly
- Rotation happens in 90-degree steps. A page scanned at a slight angle cannot be straightened here — that requires deskewing, which means re-rendering the page and losing the text layer.
- It cannot detect which pages need rotating. You have to look at them and decide; nothing analyses the content to work out which way is up.
- Rotating does not change the page dimensions. A landscape page rotated to portrait is still a landscape page turned on its side, which is correct but can look unexpected next to genuinely portrait pages.
- Bookmarks and internal links may not survive, because the document is reassembled rather than edited in place.
- Encrypted files must be unlocked first, since the pages cannot be read while the document is encrypted.
Compared with rotating in a PDF reader
| This tool | Your reader's rotate button | |
|---|---|---|
| Does it persist | Yes — written into the file. | No — a view setting that resets. |
| Does the recipient see it | Yes, in any reader. | No. They see the original orientation. |
| Does it affect printing | Yes. | Usually not — printers read the stored value. |
| Quality | Lossless. | Lossless, but nothing is saved. |
| Per-page control | Yes. | Varies by reader. |
| Where your file goes | Nowhere — it stays in the tab. | Nowhere, but also nowhere saved. |
