Based on Daniel’s code I wrote a function that simply rotates an image if necessary, without resampling. GD function image_fix_orientation(&$image, $filename) { $exif = exif_read_data($filename); if (!empty($exif[‘Orientation’])) { switch ($exif[‘Orientation’]) { case 3: $image = imagerotate($image, 180, 0); break; case 6: $image = imagerotate($image, 90, 0); break; case 8: $image = imagerotate($image, -90, 0); break; … Read more
Use the auto-orient option of ImageMagick’s convert to do this. convert your-image.jpg -auto-orient output.jpg Or use mogrifyto do it in place mogrify -auto-orient your-image.jpg

If you only want the orientation tag and nothing else and don’t like to include another huge javascript library I wrote a little code that extracts the orientation tag as fast as possible (It uses DataView and readAsArrayBuffer which are available in IE10+, but you can write your own data reader for older browsers): function … Read more
You can use the _getexif() protected method of a PIL Image. import PIL.Image img = PIL.Image.open(‘img.jpg’) exif_data = img._getexif() This should give you a dictionary indexed by EXIF numeric tags. If you want the dictionary indexed by the actual EXIF tag name strings, try something like: import PIL.ExifTags exif = { PIL.ExifTags.TAGS[k]: v for k, … Read more
exiftool does the job for me, it’s written in perl so should work for you on any o/s https://exiftool.org/ usage : exiftool -all= image.jpg UPDATED – as PeterCo explains below this will remove ALL of the tags. if you just want to remove the EXIF tags then you should use exiftool -EXIF= image.jpg
The github project JavaScript-Load-Image provides a complete solution to the EXIF orientation problem, correctly rotating/mirroring images for all 8 exif orientations. See the online demo of javascript exif orientation The image is drawn onto an HTML5 canvas. Its correct rendering is implemented in js/load-image-orientation.js through canvas operations. Hope this saves somebody else some time, and … Read more
