Why a photo can be sideways in the first place
A camera sensor is rectangular and does not turn when you turn the camera. When you hold a phone upright, the picture is still recorded in the sensor's own orientation, and a small tag is written into the file saying which way up it should be shown. That tag is part of EXIF, the block of camera data that has travelled inside photographs since 1995. Software that reads the tag shows the photograph upright; software that ignores it shows the sensor's version, lying on its side. This is why the same file looks right on your phone and wrong when uploaded somewhere, and it is the reason most rotation is needed at all.
Where you need it
Scans that came out of the feeder the wrong way up; photographs taken in portrait that every program insists on showing in landscape; a PDF whose pages were scanned sideways and are painful to read; a document whose first page is upright and whose appendix, scanned separately, is not. Rotation is also the quickest cure when a file has to be sent somewhere that will not read the orientation tag.
Questions people ask
Why does my photo look right on my phone but sideways on the computer?
Because the two are reading the same file differently. The photograph is stored in the sensor's orientation with a tag saying how to turn it; the phone obeys the tag, and the other program does not. Rotating the image here resolves the disagreement permanently: the pixels themselves are turned and the tag is set to upright, so every program agrees from then on, whether it reads the tag or not.
Does rotating lose quality?
Not in a quarter turn. A rotation by 90, 180 or 270 degrees moves whole pixels into new places without having to invent any, so the image that comes out is exactly the image that went in. Rotation by some other angle is a different matter: the new grid does not line up with the old one, every pixel has to be estimated from its neighbours, and the picture softens slightly. The pages here turn in quarter turns, so nothing is lost.
Does the file lose quality?
It depends on what the two formats can hold. Converting between formats that store the same thing — a PNG to a BMP, a WAV to a FLAC — loses nothing. Converting into a format that throws information away to save space, such as JPEG or MP3, loses a little every time, and converting back does not bring it back. Where a choice exists, this page errs towards keeping the original quality rather than making the smallest file.
Is my file uploaded anywhere?
No. The conversion happens inside your browser, on your own machine; the file never leaves it and there is no server here that could receive it. That is why a large file is limited by your own memory rather than by an upload, and why nothing you convert can appear in anybody's logs — including ours. The audio and video tools do fetch their conversion engine from this site the first time you use them, some thirty megabytes once; after that the work still happens entirely on your machine.
Why people rotate PDF files
Few things are more irritating than a PDF that opens sideways. You scan a stack of pages and half of them come out landscape. You photograph a document with your phone held the wrong way up. A colleague sends a report where one page is upside down. A scanner feeds the paper in the wrong direction and the whole file is turned. You can tilt your head, or turn the screen, but the document is still wrong, and it will be wrong for everyone you send it to. The remedy is to rotate the PDF so that every page is the right way up, once, in the file itself.
The need is constant and comes from ordinary places: scanned paperwork, photographed pages, documents assembled from different sources, forms printed in landscape and mixed into a portrait file. Whenever the way the page was made does not match the way it should be read, rotating the PDF puts it right. And because it is a small, simple fix, it is worth doing before the file is sent, printed, archived or merged with anything else.
This page lets you rotate PDF files entirely in your browser. The document is not uploaded to a server, which matters for contracts, medical papers and personal documents. Below you will find how the rotation works, why nothing is redrawn, what the limits are, and how to avoid the common mistakes.
How the rotation works
A page carries its rotation as a number
Here is the neat thing about PDF: every page records which way up it should be shown, as a single number. That number is the rotation. When you rotate a PDF, the program only changes that number for the pages you choose, and leaves the rest of the page exactly as it was. The page's content is not rewritten, redrawn or re-rendered. It is simply told to be shown turned.
Nothing is redrawn
Because only the number changes, everything is kept exactly as it was: the text, the pictures and the file size. A rotated page is as sharp as before, its text is still selectable and searchable and the file is no larger than before. There is no quality loss at all, which makes rotation one of the safest things you can do to a PDF.
Why this is better than "print to PDF"
Some tools fix orientation by printing the document to a new file, which re-renders every page and can turn text into a picture. Rotating the page number avoids that entirely. If you have ever rotated a PDF by printing and found it had become blurry or unsearchable, this is the reason, and it is why a real rotation is better.
What you can choose
Quarter turns only
A PDF page can be rotated by 0, 90, 180 or 270 degrees, and nothing in between. This is the way the format records rotation: whole quarter turns. So you can turn a page a quarter to the right, a quarter to the left or half a turn, but you cannot straighten a slightly crooked scan by a few degrees. For a page that was scanned at a slight angle, a different kind of tool is needed.
All pages or some
You can rotate every page, or only the ones that need it. A document with a single landscape page in a portrait file needs only that one turned. A scan where every page came out sideways needs all of them turned. Choose the pages carefully, and check the result.
How to tell which way to turn
Look at the page: if the top of the text points to the right, the page needs a quarter turn to the left to be upright; if it points to the left, a quarter turn to the right; if it points down, a half turn. When in doubt, try a quarter turn and look at the preview.
What the limits are
Only whole quarter turns
As noted, a PDF page records its rotation as 0, 90, 180 or 270 degrees. That is a limit of the format, not of this page. A slightly skewed scan cannot be fixed by rotating; it would need to be deskewed with an image tool before it is made into a PDF.
A signed PDF loses its signature
A digital signature is bound to the exact contents of the file. Rotating a page writes the file afresh, so the file is no longer the one that was signed, and the signature no longer applies. If a document has to stay signed, do not rotate it. If you must rotate a page, do it before the document is signed, so the signature covers the finished file.
Order of operations for signed documents
Get the document into its final form first: pages in the right order, the right way up. Then add the signature last. If the signature was applied by someone else and cannot be repeated, keep a separate rotated copy for reading, and keep the signed original untouched as the record.
What a PDF page is, and why rotation is so cheap
A PDF page is a set of instructions for drawing text, lines and pictures at certain positions. Alongside those instructions, the page has a small record of settings, including a number that says which way up it should be shown. Readers draw the page by following the instructions and then turning the whole result by that number of degrees. When you rotate a PDF, you are editing that one number, nothing else. That is why the operation is instant, why the file does not grow and why the quality cannot suffer.
It is also why rotation behaves in one slightly surprising way: the turn you choose is added to whatever the page already had. A page that a scanner marked as already turned a quarter will, when you add another quarter turn, end up turned half way round. This is exactly what you want most of the time, since it keeps the displayed result predictable, but it means you should look at the preview rather than assume the page started at zero.
Why scanners get it wrong
Scanners often feed paper in one direction while the page is meant to be read in another, particularly with landscape pages, bound documents and mixed batches. Some scanners record the orientation in the page's rotation number and some do not. Either way, you end up with pages that need a turn. Rotating the PDF corrects it without touching the scanned picture itself, so a scan turned upright this way is exactly as sharp as it was.
Choosing which pages to rotate
You can name the pages to turn in the way people usually write page lists: single pages separated by commas and ranges joined by a dash, so 3, 5, 7-9 means page 3, page 5 and pages 7 to 9. If you leave the list empty, every page is turned, which is what you want when a whole scan came out sideways. This lets you fix a single stray page without disturbing the rest, and it saves you from rotating a perfectly good page by mistake.
The page numbers refer to the position of each page in the file, as your PDF reader counts them. Printed numbers on the pages may differ if there is a cover or contents page. Check against the reader's counter before you rotate PDF pages by number, or you may turn the neighbouring page.
A mixed document
Imagine a thirty-page file in which most pages are portrait, but pages 12 to 15 are landscape tables that were scanned with their tops to the right. You would rotate PDF pages 12-15 by a quarter turn to the left and leave the others alone. Naming the range takes seconds and gives a file in which every page can be read without turning your head or the screen.
Rotating before you do anything else
Orientation is the sort of thing that is easy to fix at the start and awkward to fix later. If you rotate PDF pages first, everything you do afterwards inherits the right orientation: a watermark runs across the page the way it should, page numbers sit at the correct foot, extracted pages arrive upright and merged files line up. If you fix it last, you may find that the numbers or the stamp you added are sideways, and you have to redo them.
A sensible order is therefore: rotate, then merge or split, then remove or extract pages, then number and stamp, and finally compress or protect. Working in that order means each step operates on pages that are already the right way up.
Landscape pages that are meant to be landscape
Not every landscape page is a mistake. A wide table or a diagram is often meant to be landscape, and readers rotate their screens to read it. If a page is deliberately landscape, leave it. If its text runs sideways within a portrait page, it needs a quarter turn. The test is whether the text reads left to right along the long side when you hold the page the way it is meant to be read.
How to rotate PDF files here
Add your PDF
Drop the PDF onto the page or pick it from your device. It is read inside your browser and is not uploaded.
Choose the pages and the turn
Pick which pages to rotate, and in which direction. If the whole file is sideways, rotate all pages by the same amount.
Rotate and check
Press the button and download the corrected PDF. Open it and scroll through: every page should be upright, in the right order, and nothing else should have changed.
Tips for a clean result
Fix orientation before other steps
If you plan to merge, number or watermark the file, rotate it first. Page numbers and watermarks added to a sideways page will be sideways too.
Check every page
A mixed file may have only a few pages that are wrong. Scroll through the whole thing, not just the first page.
Keep the original
Rotation never degrades the file, but keep the original anyway, especially if it is signed.
Rotate PDF pages and keep the rest intact
When you rotate PDF pages here, the pages you do not name are left exactly as they were. That is useful for long documents: you can rotate PDF pages 12 to 15 and be certain that the other pages are untouched. If you later need to rotate PDF pages again, you can start from the original, or from the corrected file, whichever is easier. In either case, the quality never changes, because every time you rotate PDF files, only a number is edited.
Questions people ask before rotating
Does rotating reduce the quality?
No. Only the page's rotation number changes, so the text, pictures and file size are untouched.
Can I rotate by a few degrees?
No. PDF pages turn in whole quarter turns only. A slightly crooked scan needs a different tool.
Why did my signature disappear?
Because the file is written afresh, so it is no longer the signed one. Rotate before signing.
Is my file uploaded?
No. Everything runs in your browser and the file never leaves your device.
Who needs to rotate PDF files
Anyone with scanned documents
Scanners often feed pages in different directions. Rotating the PDF puts every page upright.
People photographing pages
Phone photos can be stored sideways. Once turned into a PDF, rotation fixes them.
Offices handling mixed documents
Files assembled from many sources often mix orientations. A quick rotation makes them consistent before filing or sending.
Common mistakes
Rotating the wrong pages
Scroll through the result to check every page, not only the first.
Rotating a signed document
It breaks the signature. Rotate first, sign last.
Expecting to straighten a crooked scan
Only quarter turns are possible. Use an image tool to deskew.
Related tools
After rotating, you can merge PDF files, split them, add page numbers or compress them. If your pages started as photographs, turn them upright first with rotate JPG or rotate PNG and then build the document with JPG to PDF. To extract the pages you need, use extract pages from PDF, and to secure the final file, protect it with a password.
When to rotate PDF files, and when not to
Rotating is right whenever pages are the wrong way up and the document will be read, shared, printed or processed further. It is the wrong move for a document that must stay signed, since the signature does not survive, and for a slightly crooked scan, which needs straightening by a few degrees rather than a quarter turn. And it is unnecessary for pages that are deliberately landscape within a portrait file.
For the common cases, such as scans, photographed pages and mixed batches, it is quick, private and lossless to rotate PDF files in the browser. Your original is never changed, so you can come back and rotate PDF pages again with a different choice whenever you like.
If the page is still wrong after rotating
Because the new turn is added to the page's existing rotation, a page can end up in a position you did not expect. If it is wrong, go back to the original and try the other direction or a half turn. There are only three possible turns, so the right one is never more than a couple of tries away, and the original stays untouched while you experiment.
Checking pages that are mostly pictures
For scans that are mostly photographs or drawings, it can be harder to tell which way is up. Look for text, a caption, a page number or a familiar shape. Page numbers and headers are the quickest clues. If the page has none, ask which way the paper was fed, or compare with the neighbouring pages.
Large PDFs and slow devices
Everything runs on your own device, so very large PDFs depend on its memory. Rotation is very light work, since only a number changes, but reading a huge file still takes a moment. A hundred pages is no trouble. If a very large scan struggles, give the browser a moment and avoid switching to other apps while it works.
Making a rotated file smaller
Rotation does not change the size of a file. If the PDF is too large for where it is going, compress the PDF afterwards. Scanned pages are the usual cause of heavy files, and a short pass of compression usually brings them to a sensible size once they are upright.
Your file stays on your device
The rotation happens locally. Your PDF is read by your own browser, the rotation numbers are changed there and the file is handed back. Nothing is uploaded, so there is no copy on a server and no one else who could see the contents. For contracts, financial documents and personal papers, that is the safe way to rotate PDF files.
A worked example
Say you scanned a ten-page report and pages 4 and 7 came out sideways, with the top of the text pointing to the right. You drop the PDF here, choose pages 4 and 7 and a quarter turn to the left. You press the button and download the corrected file. You scroll through: all ten pages are upright, the text is as sharp as before and the file is the same size. You send it on.
A simple routine to rotate PDF files well
Open the document and scroll through it, noting which pages are the wrong way up. Decide the turn for each group: a quarter turn one way, a quarter turn the other way or a half turn. Then rotate PDF pages in one pass, naming the pages if only some need turning, or leaving the list empty if all do. Open the result and scroll through again to confirm. If a page is still wrong, go back to the original and rotate PDF pages with a different turn. It takes a minute, and it works whether you rotate PDF files once a month or every day.
When you rotate PDF files regularly, for example from a scanner that always feeds the same way, you will soon know which turn is needed. Keep the original scans, name the corrected files clearly and rotate PDF files before any other step. That one habit prevents sideways pages from ever reaching a client, a court or a colleague, and it costs nothing in quality, because only the page's rotation number is changed.
Finally, if you are ever unsure whether a page needs a turn, remember that the cost of trying is zero. You can rotate PDF pages, look at the result and, if it is wrong, start again from the original. Nothing is lost, nothing is redrawn, and the file is never damaged by the experiment.
Before you close the page
Check that you downloaded the corrected PDF, that every page is upright, and that you kept the original, especially if it was signed.
Summary
To rotate PDF files here, drop the file, choose the pages and the turn, and download the result. A page carries its rotation as a number, so turning it only changes that number, and everything else is kept exactly: the text, the pictures and the file size. Only whole quarter turns are possible, and a signed PDF loses its signature because the file is written afresh. Nothing leaves your device.
