Rotate a PDF

A plan sheet scanned landscape, a stack that fed in backwards, a photo page that came out on its side. Turn the pages that need it, leave the ones that do not, and download a file that opens the right way up for everybody. When a whole scanner run came in the same way wrong, hand over the folder instead and turn all of it at once.

A scan that came in sideways is not a broken file, it is a page carrying a rotation of zero that should have said ninety. Fixing it writes one number per page, so nothing is re-drawn and nothing is re-compressed.

How it works

  1. Choose the PDF and every page is drawn as a thumbnail. Or drop the whole folder of them, up to twenty at once, and skip the thumbnails.
  2. On one file, rotate everything at once or click the pages that are wrong and rotate just those. On a folder there is one question instead: which way to turn every page in all of them.
  3. Download. The rotation is saved into the file, not just into your screen. One file comes back as a file, a folder comes back as one zip with the same names inside.

What you get

  • Rotate every page, or only the ones you select
  • Left and right on each individual page
  • A thumbnail that redraws at the new angle, so there is no guessing
  • Mixed documents handled, where some pages are portrait and some are landscape
  • A whole folder in one go, up to twenty files, every page turned the same way, back as one zip
  • A file that will not open is named rather than silently dropped, so you know which original to keep
  • No quality loss, because the page turns rather than being redrawn
  • No upload, no watermark, no account

Why rotating in your reader does not stick

Most PDF readers have a rotate button, and on most of them it only changes what you are looking at. Close the file, send it, and it opens sideways again for the next person. That is because the view was rotated, not the document.

This writes the rotation into the page itself, which is a property the PDF format actually stores. Every reader, every printer and every permit portal then shows it the same way you do.

Where sideways pages come from

Sheet feed scanners fed a landscape drawing through the portrait way. Phone cameras used to photograph a document taped to a wall. A large format plan reduced to letter by whoever sent it. And the classic, a two sided stack loaded upside down, which produces a file where every other page is rotated 180 degrees.

That last one is what the select and rotate buttons are for. Rotate the selection twice and only the affected pages move.

A scanner run goes wrong all at once

A page is rarely sideways on its own. The feeder was loaded the same way for the whole run, so the whole run came out the same way wrong: forty inspection reports all a quarter turn out, a morning of receipts all upside down, a set of as builts scanned landscape because the drawings are landscape and the scanner was not asked. Opening twenty files one after another to press the same button twenty times is not work, it is just time.

So hand over the folder. Up to twenty files at once, one question asked once, which way to turn. Every page in every file gets that turn and they come back as one zip called pdfs-rotated.zip with your own file names inside it, ready to send on.

There are no thumbnails on that screen, on purpose. The thumbnails exist so you can pick the pages that are wrong, and in a folder you are not picking. What is left is the question the thumbnails were there to answer.

Which means the folder is the wrong screen when only some pages in some files are wrong. That really is per file work, and the answer is to open them one at a time here, or to use delete and reorder pages if they need reordering too. This tool cannot tell which way up a page is supposed to be, and it does not guess. It turns what you tell it to turn.

It matters more on a submission than on a screen

A human reviewer will tilt their head. An automated intake will not. Permit portals, insurance claim systems and lien filing services all run text extraction on what you upload, and a rotated page can come back with the text in the wrong reading order or with nothing found at all.

If the page is rotated and also in the wrong place in the document, fix both at once in delete and reorder pages, which has the same rotation controls with reordering on top.

Nothing is uploaded

The file is opened, drawn and rewritten by your own browser. Nothing is sent to this site, because this site has no place to send it to. Load the page, disconnect, and the tool still works.

Questions people ask

Does the rotation stay when I email the file?

Yes. It is written into the page, so it travels with the document and every reader shows it the same way.

Will it reduce quality?

No. The page is turned, not re rendered. Text stays selectable and a scan keeps its original resolution.

Can I rotate only some pages?

Yes. Click the pages you want, then use the rotate selected buttons. Each page also has its own left and right buttons.

How many files can I rotate at once?

Twenty. That is a limit on what one browser tab can sensibly hold open at the same time, not a paywall in disguise, and if you hand it more than twenty it takes the first twenty and tells you so. All of the work happens on your own device, so a big batch takes a while and on a phone it will use the battery.

Does a folder rotate every page, or only the wrong ones?

Every page in every file, the same way. Nothing on this site can tell which way up a page is supposed to be, so it does not guess. If only some pages are wrong, open those files one at a time and use the thumbnails, which is what they are for.

What is in the zip?

Every file that opened, under its own name, inside a folder called rotated. Each line in the list tells you how many pages were turned in that file. If two of your files had the same name, the second gets a (2) added so neither one is lost, and a file that would not open at all is named on its own line and left out, so you know which original to keep.

Is my document uploaded?

No. Everything happens on your own device inside the browser.

How do I fix pages that are upside down?

Rotate them twice in the same direction, which is 180 degrees. If it is every second page, select the even pages first.

What about a password protected PDF?

It will not open. Save an unprotected copy in your PDF reader first, then rotate that.
