JPEG Lossless Rotator
Free, simple software for rotating your photos into the correct orientation
When photos are taken, the camera may be held in different orientations, which makes it necessary to rotate some photos in order to display them correctly on the computer screen. When rotating JPEG photos, most image editors decode the photo, rotate the bitmap and then re-encode it back to JPEG. This process decreases the final image quality. Unlike those tools, JPEG Lossless Rotator does not recode the images and performs a special lossless block transformation instead, which helps to preserve the quality of the images. In addition, JPEG Lossless Rotator has a very simple multilingual interface and is very easy to use even for inexperienced computer users.
- Shell integration — rotate your JPEG photos with a right-click on a file or folder!
- Automatic rotation.
- Batch rotation.
- EXIF-data display.
- Flipping, deletion and renaming of files.
- Command line interface.
- Multilingual interface: Asturian, Albanian, Basque, Brazilian Portuguese, Bulgarian, Catalan, Chinese (simplified and traditional), Czech, Danish, Dutch, English, Finnish, French, Galician, German, Greek, Hungarian, Indonesian, Italian, Korean, Polish, Portuguese, Romanian, Russian, Serbian, Slovak, Spanish, Swedish, Thai, Turkish, Valencian and Welsh.
In addition, according to iPhone users and the Apple Support Communities (discussions.apple.com), JPEG Lossless Rotator fixes the problem of locked iPhone 4 and 4S photos.
Photos taken in portrait mode with iPhone 4 and 4S do not auto-rotate when imported to Windows Seven, even if the user explicitly set the Windows import utility to auto-rotate them on import. Sometimes, the photos appear locked in the wrong orientation and cannot be subsequently rotated with the various Windows 7 built-in photo-editing tools. The problem results in error messages “Windows Photo Viewer can't save the changes to this picture because there's a problem with the picture's file properties”, “This photo can't be saved because of a problem with the photo's file properties”, or “You cannot rotate this image. The file might be in use or open in another program, or the file or folder might be read-only” in Windows 7 when the user tries to edit or rotate the photos taken with iPhone 4 or iPhone 4S and imported via USB to Windows 7 or synced via iCloud. If you are facing this problem, try JPEG Lossless Rotator.

If you are not planning to use the shell integration, you can download either portable JPEG Lossless Rotator or the installer. If you want to use the shell integration, you should download the installer.
Install JPEG Lossless Rotator. If you want to be able to rotate images via context menu, select “Integrate JPEG Lossless Rotator with shell” option during the installation. Start the program and use the Browse button to open a folder with JPEG/JPG images. After you choose a folder, the program will create thumbnails of the images. If Include subfolders option is chosen, thumbnails of all JPEG and JPG images in all subfolders will be also created. Now you can select a thumbnail of a picture (or a few thumbnails by dragging mouse with left button pressed) and use one of the main buttons:
Rotate Left rotates selected image(s) 90 degrees counter-clockwise.
Rotate Right rotates selected image(s) 90 degrees clockwise.
Rotate 180° rotates selected image(s) 180 degrees, i.e. turns the image(s) upside down. This button also contains a drop-down menu with Flip Horizontal and Flip Vertical actions.
Recent Folder re-opens the folder that was opened before the last program closure.
Favorites adds and keeps the 10 last chosen shortcuts to folders.
Automatic finds and rotates images that can be rotated to normal orientation automatically.
View Image opens full size image in your default picture viewer.
Delete deletes the image from the disc.
Display EXIF opens the EXIF Properties window and displays the information contained in the EXIF tags of the image. Note: JPEG Lossless Rotator updates EXIF orientation tag after rotation, however, once a normal value of the orientation tag is achieved, it remains normal regardless of subsequent rotations — this allows to achieve the correct orientation of the photos taken with cameras without an orientation sensor.
The Options menu contains additional settings and functions:
- Refresh re-creates the thumbnails.
- Rebuild thumbnails when window resized changes the thumbnails size to fit the new window size. If this option is disabled, the size of the thumbnails does not change and scroll-bars appear if the window has been downsized.
- Thumbnails in row... sets the amount of thumbnails in each row in the main window.
- Enlarge small thumbnails enlarges previews of the images that are smaller than the thumbnail size.
- Keep file timestamp leaves the file’s modification date and time unchanged despite the performed rotations.
- Preserve a copy of original images makes a copy of each image before it was rotated and saves that copy in the folder with the original image. Each unrotated copy has word _ORIGINAL added to its file name.
- Display delete confirmation dialog shows a confirmation message when you try to delete an image by clicking Delete button.
- Display explorer tree shows or hides the file explorer tree on the left side of the main program window.
- Display crop warning shows a warning message when an image needs to be cropped for lossless rotation.
- Background color lets a user to choose the colour of the program window.
- Text color lets a user to set the colour of the file names displayed under thumbnails.
- High thumbnail quality (slower)/Low thumbnail quality (faster) defines the speed of thumbnail creation and the quality of thumbnail images. This does not have any effect on the actual image quality.
Click the right mouse button on a thumbnail image preview for one of the following functions:
- View image (opens the image in the default image viewer)
- Rotate right
- Rotate left
- Rotate 180°
- Display EXIF
- Flip horizontal
- Flip vertical
A double click on a thumbnail image preview opens the full-size image in the default image viewing program.
Some of the main menu buttons and right-click actions have associated keys for a faster access:
- Arrow keys — to choose an image
- Enter — to view the full size image
- R — to rotate the image rightwards
- L — to rotate the image leftwards
- U — to rotate the image 180°
- E — to show the EXIF-data
- H — to flip the image horizontally
- V — to flip the image vertically
- Ctrl+R — to rename the image file
- Ctrl+Del — to delete the image
EXIF orientation reset
The EXIF Properties window (accessed via Display EXIF button or E hot key) has the “Reset EXIF Orientation to Normal” button. It sets the orientation tag value to normal without rotating the image. This function takes the “Keep file timestamp” setting into account. Resetting EXIF tag to normal may be very helpful for achieving correct display of the photos that appear to be oriented correctly but, for some reason, have incorrect EXIF tag value; this often happens when photos are taken with the camera pointing down.
Shell Integration (available in the installer)
You can click on a JPEG/JPG file icon with the right mouse button and choose “Lossless Rotate Right” or “Lossless Rotate Left” context menu item to rotate the picture. The same works for a selected group of JPEG files.
Note, JPEG Lossless Rotator integrates into shell and creates context menu items only if you chose “Integrate JPEG Lossless Rotator with shell” option in the setup window when you were installing the program.
You can also automatically rotate all JPEG images in a folder by clicking the right mouse button on the folder and choosing “Automatically Rotate JPEG Images” menu item (provided that the JPEG files have orientation tags). This command will rotate images in all subfolders if you have the “Include subfolders” option checked in the main program window.
JPEG Lossless Rotator allows you to use command line for image transformation. The command format is: <Path to jpegr.exe> jpegr.exe -[r|l|u|v|h] [-s] <filename>
- r — rotate the image to the right
- l — rotate the image to the left
- u — rotate the image 180°
- h — flip the image horizontally
- v — flip the image vertically
- s — suppress all warning messages
Enclose the filepath in quotes if your JPEG Lossless Rotator program file or image file paths contain spaces.
You can also run Automatic Rotation function using command line. The command format is:
<Path to jpegr.exe> jpegr.exe -auto <Path to a folder with JPEG files>
To include all subfolders, type -autosub instead of -auto. The program outputs messages as message boxes (not in the command prompt), so you can use any command line, like “Run...” in Windows Start menu, for example by typing "C:\Program Files\JPEG Lossless Rotator\jpegr.exe" -auto "D:\My Photos\". Paths with white spaces may require to be enclosed in double quotes.
Over the years, a few users let me know that JPEG Lossless Rotator did not work correctly with their photos. JPEG images have a very complex file format and some photo camera manufacturers may vary its structure. Therefore, I would recommend to test JPEG Lossless Rotator on a few unneeded photos created by your camera with the usual resolution before using the program extensively.

Frequently Asked Questions
I can’t select multiple non-contiguous files by holding the CTRL key and clicking on thumbnails. What’s wrong?
Unfortunately, due to the specific behaviour of the thumbnail grid, it is only possible to select either a single thumbnail or multiple thumbnails forming a continuous rectangular area (next to each other and/or above/below each other).
Why doesn’t automatic rotation do anything to my photos?
If your camera is equipped with an orientation sensor to detect its orientation (horizontal, 90°CW, or 90°CCW) when you hold it, it can embed that information in the photo’s EXIF tag. JPEG Lossless Rotator then reads this tag and rotates the photo according to the value of the tag. This is the automatic rotation.
However, some cameras do not have the orientation sensor or have it switched off in the camera settings, which means they always put “Horizontal/Normal” value in the EXIF orientation tag. Such photos cannot be rotated automatically, because the orientation tag tells JPEG Lossless Rotator that the photo doesn’t need to be rotated. You still can turn these photos into correct orientation manually by using JPEG Lossless Rotator’s rotate buttons.
In JPEG Lossless Rotator’s main window, select a photo that obviously needs rotation and was not taken with the camera lens pointing upwards or down. Then click the “Display EXIF” button and have a look what the “Orientation of the camera” line says. If you see “Top/left-hand side (Normal)”, then your camera either does not have the sensor, or the sensor needs to be switched on. Refer to your camera user manual to find out what settings to use to switch its orientation sensor on.
Why does automatic rotation rotate correctly oriented photos to an incorrect position?
It can happen if images were rotated earlier in another program and that program did not update the EXIF tags. Such images appear to look right, but their EXIF orientation tags still contain the original information, which tells JPEG Lossless Rotator that the images need to be rotated. As JPEG Lossless Rotator’s automatic rotation relies on EXIF tags, it rotates the images according to what EXIF tells it and makes them appear incorrectly oriented. To fix this discrepancy between the appearance of the images and the information in their EXIF tags created by another software, you can correct the EXIF information of those photos with the Reset EXIF Orientation to Normal function (accessed via Display EXIF button or E hot key) before performing automatic rotation for the whole folder.
Why does JPEG Lossless Rotator not work correctly with photos of book pages, while it works perfectly with photos of landscapes, buildings and people? Automatic rotation rotates some pages incorrectly, and if I rotate them manually, then my viewer shows some pages incorrectly.
When you are taking photos of book pages with the book lying horizontally on a table, your camera lens is pointing down. In this position, the camera’s orientation sensor may make an error and assign an incorrect value of the EXIF orientation tag to the photos.
JPEG Lossless Rotator’s automatic rotation is guided by the EXIF orientation tags, and if these tags have an incorrect value, the result of the automatic rotation is also incorrect.
When you rotate these photos manually, you can see that thumbnails of the photos in JPEG Lossless Rotator show the correct position. However, because the initial value of the EXIF orientation tag was incorrect, the value after the rotation becomes incorrect too. Now, if your viewing program has an ability to show photos according their EXIF information, it will use the incorrect EXIF data and will display the photo in a wrong orientation, even though the photo is physically rotated correctly.
To achieve both a correct position of the photos and correct EXIF information, you should:
- Apply JPEG Rotator’s automatic rotation to the photos. Do not worry that some photos will be rotated incorrectly.
- Manually rotate those incorrect photos to their correct position.
Now your photos are in their correct position and their EXIF tags are correct too.
Why do Windows thumbnails not change when I rotate photos using context menu in Windows explorer*, but when I open the photos in a viewer they are all rotated correctly?
If Windows thumbnails cache is on, Windows does not update thumbnails unless file modification date is changed or you update them manually. There are two ways to solve this problem:
- If you do not need to keep your files’ date, you can uncheck “Keep File Timestamp” option in JPEG Lossless Rotator's “Options” menu.
- If you do want to keep your files’ date, you can switch Windows thumbnails cache off. To do so, open “My Computer”, then choose “Tools” menu, then choose “Folder Option” menu item, and then open the “View” tab. Now check “Do not cache thumbnails” list item. After you do this, Windows will stop creating thumbs.db files that contain cached thumbnails. It will take Windows a bit longer to create thumbnails when you open a folder with images, but, on the other hand, it will reduce the amount of system files cluttering your discs. This procedure is not applicable to Windows Vista, 7 or 8. If you use Windows Vista or 7, there is an option to clear the thumbnail cache in the Disk Cleanup (click Start, type cleanmgr or disk cleanup, select the system drive letter and check Thumbnails in the list of files to delete).
* Please note that there are two commonly used computer-related “explorers”: the Internet Explorer — the popular Internet browser, and the Windows Explorer — the Windows file manager that provides a graphical user interface for accessing the file system (all those windows, folders, thumbnails and buttons). Here we are talking about the second one, the Windows Explorer.
Why does JPEG Lossless Rotator show orientation EXIF tag value as Right-hand side/top (Rotate 90 CW) when I see that my photo is on its left side?
The EXIF specification defines an orientation tag to indicate the orientation of the camera relatively to the captured scene. If the program shows the value Rotate 90 CW, it means that your camera was on its right side (for you, looking through the viewfinder) when you captured the photo. “Right-hand side/top” in this case means that the 0th row is on the compositional right-hand side of the image, and the 0th column is at the compositional top (in the normal position the 0th row is at the visual top of the image, and the 0th column is on the visual left-hand side).
Where are the original photos that I had before the rotation?
By default, JPEG Lossless Rotator rotates and overwrites the original photos. It does it for several reasons:
- most users don’t need the original photos with wrong orientation;
- most users want to save their disk space;
- most users don’t want to remember which photos are already rotated and which are not.
If you want to keep the original files intact, set the Preserve a copy of original images option in the JPEG Lossless Rotator’s Options menu. Alternatively, you can make a copy of the files before the rotation.
Is the rotation by JPEG Lossless Rotator really lossless?
It is lossless for any JPEG/JPG file when width and height (number of pixels) are divisible by 16 or 8 (depends on the digital camera or the way the image was created). Almost all common photo formats have width and height divisible by 16. For example, 3456x2304, 3072x2304, 2816x2112, 2560x1920, 2496x1664, 2048x1536, 1728x1152, 1600x1200, 1280x960, 1024x768, 800x600, 640x480, 320x240. If your camera creates photos with a size that is not divisible by 16, JPEG Lossless Rotator may not suit you.
Why some JPEG images cannot be rotated losslessly?
JPEG file structure does not allow lossless rotation of a file if its width and height are not divisible by 16 or 8 (depends on the digital camera or the way the image was created). If a file cannot be rotated losslessly and you haven’t switched the crop warning messages off in the settings, JPEG Lossless Rotator will ask you whether you want to crop the image edges by up to 15 pixels to make lossless rotation possible.
If the program does crop an image, it crops the right and/or* bottom sides, which become bottom and left sides if you rotate 90°CW, top and right sides if you rotate the images 90°CCW, and left and upper sides if you rotate 180 degrees.
* “and/or” depends on whether the width only, height only, or both sides are not multiple of 16 or 8.
Why does the file size change? It was 1352 KB, and then it became 1297 KB! What’s happened? My photo is 1024x768, so it should be rotated losslessly.
JPEG file size change does not mean the same quality change. When you rotate your photo, JPEG-blocks have a new position and file size may be changed (decreased or increased).
