Detect EXIF Orientation and Rotate Image using ImageMagick

Canon DSLRs appear to save photos in landscape orientation and uses exif::orientation to do the rotation.

Question: How can imagemagick be used to re-save the image into the intended orientation using the exif orientation data such that it no longer requires the exif data to display in the correct orientation?

Solution

  • 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
