How to rotate PDF
Rotation is written into the file, so the page opens the right way up everywhere — not just in your viewer.
- Open your PDF. Every page appears as a thumbnail.
- Choose the pages. Rotate one page, a selection, or all of them at once.
- Rotate and download. The new orientation is saved into the document.
What a rotation writes into the file
Rotating sets one number on each page. A PDF page carries a rotation of 0, 90, 180 or 270 degrees, and that is the only thing this tool touches: the content stream, the embedded fonts and every image are copied across as they are, so nothing is re-compressed and the text stays exactly as selectable as it was. The turn is added to the rotation the page already carries rather than replacing it, so a scan already marked landscape opens the way it does today and moves a quarter turn on from there — which is what the thumbnails show you.
The document is rebuilt around those pages rather than edited in place, and that has a cost worth knowing. Each page brings its own content and the annotations sitting on it, but what a PDF holds at document level does not travel: the bookmark outline, the form dictionary and the title and author properties are not carried into the new file, so a fillable form comes back with its values showing but its fields no longer editable. The wait on a long document is not the rotating either — every page is rendered as a thumbnail before you can pick anything, and on a few hundred pages that is the part you are waiting for.
Rotation, tilt and sideways pages are three different problems
Rotation moves in quarter turns only. A scan that is three degrees out is skewed, not rotated, and no number of 90° turns will square it up — Deskew PDF measures the angle and corrects it. The reverse holds too: a page lying a full quarter turn round is not skew, and deskew searches only 8° either side of upright, so it passes straight over that page and reports the document as straight.
Do the rotating before anything that reads the page as a picture. OCR PDF renders each page through the same viewport a reader displays it in, rotation included, and nothing asks the recogniser to work out which way up the page is — so a sideways page comes back as sideways nonsense, while the same page turned upright reads cleanly. PDF to JPG exports through that viewport too, so the orientation you fix here is the orientation the images have.
Questions
Why does my viewer show it correctly but printing comes out sideways?
Some viewers rotate on screen without saving it. This tool writes the rotation into the file itself, so printers and other readers agree with what you see.
Does rotating re-compress the pages?
No. Rotation is a property of the page, so nothing is re-rendered and no quality is lost.
Can I rotate only one page?
Yes. Click the pages you want, then use rotate left or right — the turn applies to your selection. With nothing selected, the same two buttons turn every page at once. Rotating nothing is refused: the tool asks you to turn at least one page before it will build a file.
Does rotating make the file bigger or blurrier?
Neither in any way that matters. Rotation is a property of the page, so nothing is re-rendered or re-compressed. The file is written out fresh, so the byte count can shift slightly in either direction, but no image is re-encoded and no text is redrawn.
Can I flip a page upside down, or mirror it?
Upside down, yes — two quarter turns give you 180 degrees. Mirroring is a different operation: it reverses the content itself rather than the page's orientation, and nothing here does that.
Are my files uploaded to a server?
No. Every tool on this site runs inside your browser, using the same engine as the Folia desktop app. Your file is read from your disk into your browser’s memory, processed there, and handed back as a download. It never crosses the internet, so there is nothing for us to store, leak or hand over.
Is there a file size limit?
We impose none. The only ceiling is your own device’s memory, which differs from one computer to another — so we read what your browser reports about this machine and show the resulting limit on the page. Light tools like merge and rotate handle far more than heavy ones like OCR, which must render every page. For anything larger, Folia for Desktop has no limit at all.
Is it really free? Do I need an account?
Yes, and no. Every tool is free and unlimited, with no watermark and no sign-up. Ads pay for the site, and your own computer does the work, which costs us nothing. Signing in with a paid Folia plan simply removes the ads.
