To remove exif data, you have to use -strip option with mogrify as shown below: mogrify -strip To list exif data, you have to follow the given command syntax: identify -format '%' Using ImageMagick to get exif data of the image Once you are done with the installation, let's have a look at how you can list image details from ImageMagick.
#Perl exiftool install#
So let's jump to the installation of ImageMagick.įor Debian-derivatives: sudo apt-get install imagemagickįor RHEL-based distros: sudo dnf install imagemagickįor Arch-based distros: sudo pacman -S imagemagick Less option does not affect its functionality and does its job quite well and this is the perfect option for those who just want to remove exif data in the simplest manner possible. Unlike the exif tool which was created to remove metadata and exif data, ImageMagick is not meant only to extract image data, so you won't get as many options as I have shown above. Now, let me show you what you are left with when you only remove exif data: Remaining info after removing exif data Method 2: Using ImageMagick To remove exif data only, you have to use the -EXIF option as follows: exiftool -EXIF=
So if you are looking for a way by which you can only remove exif data, you only have to follow a slight change in command and that's it. exiftool -recurse -all= Removing metadata of each image present in the directory Removing Exif Data Only It makes a copy of the original file and removes metadata from the copied file and the original file will be renamed with "_original" appended at the end of it. To remove metadata from an entire directory, you have to use -recurse option, which will instruct ExifTool to traverse subdirectories. This command will come in handy if you want to remove the metadata of an entire directory containing images. exiftool -overwrite_original -all= Applying changes only to the original file Removing Metadata from Entire Directory What if you want to remove the metadata of an image without creating a new copy and want to modify the original image? Use -overwrite_original option. Getting exif data of a specific imageĪs you can see, I've managed to remove exif data from my image and there is no reduction in size as there's no compression involved. Let's use the exif command again to list the exif data of our new file. exiftool -all= A new image file with no metadata and an old file renamed for backup It will create a copy of the image with no metadata, and the original file will be renamed with “_original” appended to the end of the file. To remove metadata, you have to use -the all option. Removing metadata from an image will also remove exif data.
#Perl exiftool software#
Where exif data only includes details about the digital image such as size, location, software used to create/modification, etc. Metadata includes details such as the creator of the file, the purpose of the file, and comments, if any. There is a difference between metadata of image and exif data. To list all the details, you have to use the given command syntax: exiftool Exif data of an image Removing Metadata from Image If you are on other platforms, such as Gentoo, you can build ExifTool from scratch here.ĮxifTool can also be used to view metadata related to the image. So let's start with the installation of various distros:įor Debian derivatives: sudo apt install libimage-exiftool-perlįor RHEL-based distros: sudo dnf install perl-Image-ExifToolįor Arch-based distros: sudo pacman -S perl-image-exiftool So if you are looking for a way by which you can have various options to remove your Exif data that does not apply any image compression, then this should be your first preference.
#Perl exiftool how to#
While this can be useful in various scenarios, it also has privacy threats and through this guide, I'll show you how to remove Exif data from images using the Linux command line.
Increased Verbose level of "nothing changed" message added in 12.Most images contain Exif (Exchangeable image file format) data which includes some crucial data such as the date and time of capturing an image, device, place, and so on.
