Why Does My Photo Show Upside Down When I Upload It but Its Right Side Up?
Always wonder why some photos look right in some programs, only appear sideways or upside down in others? That'southward because there are two unlike ways a photo tin exist rotated, and non every program is on the same page.
The Two Means an Epitome Can Be Rotated
Traditionally, computers take always rotated images by moving the actual pixels in the prototype. Digital cameras didn't bother rotating images automatically. So, fifty-fifty if you used a camera and held it vertically to take a photo in portrait mode, that photo would be saved sideways, in landscape mode. You could so use an prototype editor programme to rotate the image to appear in its correct portrait orientation. The prototype editor would move the pixels to rotate the image, modifying the actual epitome data.
This merely worked, everywhere. The rotated image would appear the same in every program…as long as you took the time to manually rotate them all.
Manufacturers wanted to solve this annoyance, and then they added rotation sensors to modern digital cameras and smartphones. The sensor detects which style you lot're holding the camera, in an effort to rotate the photos properly. If you lot accept an image in portrait mode, the camera knows and can act accordingly so you don't have to rotate it yourself.

Unfortunately, there'south a modest caveat. Digital camera hardware but couldn't handle saving the image directly in rotated form. So rather than performing the computationally intensive chore of rotating the entire image, the camera would add together a pocket-size piece of information to the file, noting which orientation the image should exist in. It adds this information to the Exif data that all photos take (which includes the model of camera you took it with, the orientation, and possibly even the GPS location where the photograph was taken).
In theory, then, you could open up that photo with an awarding, it would look at the Exif tags, and then present the photograph in the correct rotation to you. The image data is saved in its original, unrotated course, but the Exif tag allows applications to correct it.
Non Every Program Is On the Same Page
Unfortunately, not every slice of software obeys this Exif tag. Some programs–especially older image programs–will only load the prototype and ignore the Exif Orientation tag, displaying the paradigm in its original, unrotated state. Newer programs that obey Exif tags will show the epitome with its correct rotation, so an paradigm may appear to have dissimilar rotations in different applications.
Rotating the image doesn't exactly help, either. Alter it in an old application that doesn't understand the Orientation tag and the application will move the actual pixels around in the paradigm, giving information technology a new rotation. Information technology'll expect correct in older applications. Open that prototype in a new awarding that obeys the Orientation tag and the application will obey the Orientation tag and flip the already rotated image around, and then it'll look incorrect in those new applications.
Even in a new application that understands the Orientation tags, it'due south often not quite clear whether rotating an image will move the actual pixels in the image or simply modify the Exif tags. Some applications offer an option that will ignore the Exif Orientation tag, allowing you to rotate them without the tags getting in the way.
This problem can occur in practically any software, from a program on your PC to a website or a mobile app. Photos may appear correctly on your computer but announced in the wrong rotation when you upload them to a website. Photos may appear correctly on your phone but incorrectly when you transfer them to your PC.
For instance, on Windows vii, Windows Photo Viewer and Windows Explorer ignore the Exif Orientation tag. Windows 8 added support for the Exif Orientation tag, which continued into Windows 10. Images may appear right on a Windows 10 or eight PC, simply rotated differently on a Windows 7 PC.
New Software Almost Ever Obeys Exif Orientation Tags
Thankfully, near applications now do obey the Exif Orientation tag. If you're using Windows 10, File Explorer and the default image viewer will properly obey the Exif Orientation tag, and so photos that come up from your smartphone or digital camera will be display properly. Google'south Android and Apple'south iOS both natively create photos with the Exif Orientation tag and back up information technology.
If yous're using Windows 7, you can make this trouble go away by upgrading to Windows 10. If you'd similar to keep using Windows 7, you lot may desire to use some other image viewer that obeys the Exif tags instead of the default epitome viewer.
The average website or desktop application should also obey Exif Orientation, although non all of them practise. If a photo appears sideways when uploaded to a website, that website needs to be fixed–but yous can probably rotate that image on that website anyway. Desktop tools for working with photos should besides support Exif Orientation tags. If an application yous employ doesn't, yous may want to detect a more modern application.
How to Fix Image Rotation for Older Programs
If this is a problem for you–especially on Windows seven–you tin can also utilize JPEG Autorotate, which uses the jhead command in the background. This tool adds a quick correct-click "Autorotate all JPEGs in folder" option to Windows Explorer. Select it and the tool will examine all photos in a folder, automatically rotating them co-ordinate to their Exif Orientation tags and so removing those tags. Employ this tool when you import images and Windows 7 and other applications won't accept a trouble with them.
Modern smartphones and digital cameras have faster hardware, so it should exist possible for them to save photos in an already-rotated country instead of just applying the Exif Orientation tag. Unfortunately, the industry seems to take settled in Exif Orientation tags as the standard solution, even if they aren't ideal.
